This describes the various menu options you can access from within the Families and Groupings program.
| Field | Description |
|---|---|
| Add | This adds a new collection, a sub-collection to an existing collection, or stock codes to a collection. |
| Change | This maintains the details of the collection currently highlighted in the Collection Structure tree view. |
| Delete | This deletes the collection (and its contents) currently highlighted in the Collection Structure tree view, or deletes the stock code currently highlighted in the tree view. |
| Delete All | This deletes all stock codes for the currently selected
collection. This option is only enabled when a SKU or consolidated warehouse items are highlighted in the tree view. If all items attached to a collection are deleted then the aggregated figures are automatically cleared. |
| Copy | This copies sub-collections and/or stock keeping units (SKUs) from one collection to another. |
| Previous Selections | This displays saved stock item selections previously
added in batch mode to a collection. This option is only enabled once you have saved at least one selection and then exited and reloaded the program. |
| Aggregate Sales History | This aggregates the sales history for the collection
from the SKUs contained therein. If the collection contains sub-collections (rather than SKUs or consolidated warehouse items) then the sales for these child collections are aggregated. Sales for the warehouses are aggregated for consolidated warehouse items. This aggregation must be performed before demand history maintenance or forecasting can be done. |
If you have a 'root' collection that contains a number of sub-collections, then you can only add stock items to the last sub-collection (i.e. to the last node in the tree).
| Field | Description |
|---|---|
| Warehouse | Enter the warehouse in which the stock code you want
to include in the collection is linked. This field is only enabled if no warehouse consolidation is selected against the collection. |
| Previous | Select this to navigate to the previous warehouse. |
| Next | Select this to navigate to the next warehouse. |
| Stock code | Enter the code of the stock item you want to add to the collection. |
| Rev/Rel | For ECC-controlled items, you use these fields to enter the revision/release of the stock item you want to add to the collection. |
| Batch Selection | Select this to add multiple stock items simultaneously to the collection. |
This screen is displayed when you select the Batch Selection option from the Add Stock Code to Collection window. The options enable you to simultaneously add a number of stock items to a collection.

This displays all saved selections for the collection (more than one selection can be saved for a single collection).
These selections are created when you add stock items to a collection in batch mode and select the Save Selections option.
You typically save selections so that you can re-generate them for the collection. For example, you may have saved a selection of stock items for a specific warehouse only. Since these were last added to the collection, additional stock items may have been added to the warehouse and you now want to include these new items in the collection. You can select the appropriate selection and process the selection to add these items to the collection. This saves you from having to delete the existing stock items and re-defining the selection.
The following information is displayed for each saved selection:
| Column | Description |
|---|---|
| Column 1 | A tick in this column indicates that the selection is currently selected. |
| Date | This indicates the date on which the selection was saved. |
| Time | This indicates the time at which the selection was saved. |
| Description | This indicates the description allocated to the selection when it was saved. |
| Field | Description |
|---|---|
| Select All | Select this to set all saved selections to selected. |
| Deselect All | Select this to set all saved selections to deselected. |
| Delete | Select this to delete the selected selections. |
| Review | Select this to view the stock codes to be added to
the collection according to the options you indicated. The
list view is displayed when you select to process the
selections. This enables you to deselect the items you do not want to add to the collection. |
| Delete existing items | Select this to delete the SKUs currently held against the collection before the selections are processed. |
| Retain manual additions | Select this to retain any existing stock items which were added manually, but to delete all existing SKUs added using the batch method. |
| Process selections | Select this to add the stock items for the selected selections to the collection. If you selected the Review option, then the stock items are displayed in a list view. This enables you to select/deselect items as required. |
| Cancel | Select this to return to the previous screen. |
| Selection information | This indicates the options selected when the selection was originally made. It is displayed for information purposes only and cannot be changed. |
| Field | Description |
|---|---|
| Date that aggregation was last performed | This indicates the date on which the sales aggregation was last performed for the selected collection. |
| End date of last period of history | This indicates the end date of the previous
forecasting period, as defined in the calendar for the
collection. The sales aggregation needs to be run if the sales history for the selected collection has not been aggregated after this date. |
| Update sales history for all SKUs in selected structure | Select this to update the sales history against each
stock item in the selected collection with the sales
transactions that occurred since the last
aggregation. The sales history and sales returns history values are held in year-to-date format in the IOPSLS (IopSales) and IOPSLR (IopSalesReturns) tables/files. While this format aids performance when retrieving history for any given period (certainly on C-ISAM), it can be tedious to update. For example, if a sale needs to be introduced to the IOPSLS file/table for the 1st May 2008 and there are 50 records for the stock code/rev/rel/warehouse in 2008 that are subsequent to this date, each of these records require updating. To avoid the effect that these potentially slow updates would have on invoicing, the IOPTRN (IopTransactions) intermediate file/table is used. However, any transactions that have been output to this file/table must be included in the sales and sales returns history before we can begin forecasting in Families and Groupings. By selecting this option, Sales Aggregation transfers sales figures from IOPTRN (IopTransactions) to IOPSLS(IopSales) and IOPSLR (IopSalesReturns). |
| Aggregate Sales | Select this to aggregate the sales for the selected
collection. For whichever collection you select, the entire hierarchy below that collection is processed. The sales history for each member of the collection for each period in the interval for which the members have a valid history is totalled. For each SKU found, the sales figures are aggregated up through any intermediate collections to the collection the process was started on. The Aggregation date and time is updated against each collection included in the aggregation. This information is displayed in the Collection Information pane. |
| Field | Description | ||||
|---|---|---|---|---|---|
| Quantities | This displays quantities in the stocking unit of
measure in the list view columns and on the graph.
|
||||
| Cost Values | This displays the cost values in the list view columns
and on the graph. Forecast cost values are calculated using the current inventory cost in the selected warehouse. |
||||
| Sales Values | This displays the sales values in the list view columns
and on the graph. Forecast sales values are calculated using the list price for the item. You can only select this if you have been denied access to the option: Show costs in Inventory/WIP queries (Operators). |
||||
| GP Values | This displays the gross profit values in the list view
columns and on the graph. Forecast gross profit values are calculated as: sales value less cost value. |
||||
| GP Percentages | This displays the gross profit percentages in the list
view columns and on the graph. Forecast gross profit percentages are calculated as: gross profit value divided by cost value, shown as a percentage. |
||||
These reports are only available at collection level (i.e. when you highlight a collection in the Collection Structure tree view). The reports are generated only for the selected collection. The collection is equivalent to the Forecasting set in Inventory Forecasting.
| Field | Description | ||||
|---|---|---|---|---|---|
| Forecast Comparison Report | This uses the Forecast Comparison program to compare current
forecasts with draft forecasts for the currently selected
collection. This enables you to check the reasonableness of
newly-generated draft forecasts.
|
||||
| List of Forecasts | This uses the List of Forecasts program to print, by forecasting
period, a list of draft and current forecasts per stock
code/warehouse/rev/rel for the collection currently
highlighted. The results are displayed by forecasting period as defined by the calendar. If the Forecast Comparison program highlights unexpected variances between draft and current forecasts, then this report can be used to investigate the items causing the variance.

| Analysis options | |||||
| Base | Indicate the basis on which the analysis must be
performed. This includes:
|
||||
| Months | Indicate the number of months to use for the
analysis. If the analysis is being performed on sales, then this determines the number of months into the past to be used in the analysis. If the analysis is being performed on either current or draft forecasts, then this determines the number of months into the future to be used for the analysis. |
||||
| Include sales adjustments | Select this to include sales adjustments in the sales figures for the analysis. This only applies if the analysis is being performed on sales. | ||||
| Replenishment items only | Select this to indicate that only items marked as a replenishment item (Options Maintenance) must be included in the analysis. | ||||
| Percentage breaks | Indicate the cumulative percentage break points between the different classes of items. | ||||
| Include | This option enables you to indicate the items to exclude from the results list view based on their calculated Pareto classification. | ||||
| Analyze | This performs Pareto Analysis on the collection
currently highlighted in the tree view of the
Collection Structure pane. If a stock item is currently highlighted in the tree view, then the analysis is performed on its parent collection. The analysis is always performed on the SKUs contained in the collection, regardless of the level at which the SKU exists in the collection (e.g. if the All Collections level is selected, then the analysis is performed on all SKUs throughout the hierarchies. The results are displayed in the Details panes.

| Field | Description |
|---|---|
| Maintain Sales Adjustments | This processes adjustments to the history to ensure
that it is representative of typical sales. If sales for the selected collection have not been aggregated since the end of the previous period (as defined by the calendar), then you are prompted to aggregate the sales. |
| Adjust for Outliers | This generates adjustment entries for periods where
sales differ from the mean by more than the value defined
against the Number of standard deviations
outliers option (Inventory Optimization - General Setup). If the selected item is found to be seasonal (i.e. its sales history falls within the seasonal profile correlation cut-off (Inventory Optimization - Forecast Algorithms Setup) then you are prompted to adjust the outliers to diminish the effect of seasonality. When you run outlier adjustments at SKU level in Families and Groupings, the changes are visible in Inventory Forecasting (and vice versa). However, If you run outlier adjustments at a collection level, they are not visible in Inventory Forecasting. |
Demand history maintenance can be performed at any level in the tree view. The adjustment entries made are held at the level at which the maintenance is performed. Therefore, adjustments made at an SKU level are held at the SKU level the same as if the adjustments were performed using the Demand History Maintenance program.
Adjustments made to a collection's sales are held against the collection and adjustments made to a consolidated warehouse stock item's sales are held against the collection/consolidated stock item.
All adjustments against a collection are accumulated up through the collection structure to the top level when creating, aggregating and disaggregating forecasts.
Sales adjustments may only be maintained if you selected Quantities, Cost Values or Sales Values from the View menu.

When you select to adjust history for outliers, the system performs the following for each stock code/rev/rel/warehouse:
- Calculates the forecasting periods' start/end dates according to the calendar associated with the item.
- Checks for and deletes any existing outlier adjustment entries for the item.
-
Reads the sales history transactions (sales, sales returns and sales adjustments) into the forecasting periods.
An item is ignored if it uses a proxy or is being used as a proxy.
-
Checks for a seasonal demand pattern if at least two years of history is available,
If the item is found to be seasonal and the Adjust for Outliers option is run from batch forecasting, it is ignored.
If the item is found to be seasonal and the Adjust for Outliers option is run from Demand History Maintenance, a warning is displayed that the item has seasonal demand. You are given the opportunity to either cancel or continue with the process.
- Calculates the average sales for all the periods since the first period with a non-zero sales quantity.
- Calculates the standard deviation for all the periods since the first period with a non-zero sales quantity.
-
Calculates the minimum sales quantity allowable as the average minus the Number of standard deviations to define outliers defined against the stock code/rev/rel/warehouse or the Inventory Optimization - General Setup (if it has not been defined at the item level)
min sales = avg sales - (std dev * no std dev’s to define outliers).
-
Calculates the maximum sales quantity allowable as the average plus the number of standard deviations to define outliers as defined against the stock code/rev/rel/warehouse or the Inventory Optimization - General Setup (if it has not been defined at the item level)
max sales = avg sales + (std dev * no std dev’s to define outliers).
-
Checks each period's sales since the first period with non-zero sales.
If a period has a sales figure less than the minimum allowable, generates an outlier adjustment entry to bring the sales figure up to the minimum.
If a period has a sales figure more than the maximum allowable, generates an outlier adjustment entry to bring the sales figure down to the maximum.
Forecasting can be performed at any level in the tree view. Suggested forecasts are generated and draft forecasts can be created regardless of the level being processed.

period. This field is only enabled if you selected Quantities from the View menu. If any other option is selected from the View menu, then this field is calculated based on the entry at the Cost value or Sales value fields if the Calculate option is selected. For stock items, the quantity is calculated using the current cost or list price. For collections, the quantity is calculated using averages based on all the history being displayed. |
| Calculate | This option is not enabled if you selected
Quantities from the View menu. If any other option is selected from the View menu, then this option must be selected to calculate the quantity based on your entry at the Cost value or Sales value fields. |
| Cost value | Enter the draft forecast cost value for the
period. This field is only enabled if you selected Cost Values from the View menu. If any other option is selected from the View menu, then this field is calculated based on the entry at the Quantity or Sales value fields if the Calculate option is selected. For stock items, the cost value is calculated using the current cost and list price if Sales values is selected. For collections, the cost value is calculated using averages based on all the history being displayed. |
| Calculate | This option is not enabled if you selected
Cost Values from the View menu.
If any other option is selected from the View menu, then this option must be selected to calculate the cost value based on your entry at the Quantity or Sales value fields. |
| Sales value | Enter the draft forecast sales value for the
period. This field is only enabled if you selected Sales Values from the View menu. If any other option is selected from the View menu, then this field is calculated based on the entry at the Quantity or Cost value fields if the Calculate option is selected. For stock items, the sales value is calculated using the list price and current cost if Cost values is selected. For collections, the sales value is calculated using averages based on all the history being displayed. |

| Current forecasts | Select this to update the current and draft forecasts. | ||||
| Periods to update | You use this option to indicate the forecasting periods' start/end dates (according to the calendar associated with the item) to be updated. | ||||
| Output method | These options enable you to indicate how the current forecasts should be updated. | ||||

| Delete draft forecasts in updated periods | Select this to remove the draft forecasts after the current forecasts have been updated. | ||||
| Apply parent algorithm through all levels |
This determines which algorithm to use when calculating suggested forecasts at each level. Enable this to apply the algorithm defined against the parent item highlighted down through all levels when calculating suggested forecasts. When this is disabled, the algorithm defined against each entity is used to calculate suggested forecasts. This can give obscure results at lower levels when the algorithm is inappropriate for the entity. If no algorithm is defined against the entity, then the Default algorithm in Inventory Optimization - Forecast Algorithms Setup is used. The suggested forecasts calculated are used to calculate the ratio to apply when updating the current level's drafts. |
||||
| Start Processing | Select this to update the forecasts according to the
options you indicated. Processing differs depending on the level being forecast. When current forecasts are updated for a collection, forecast disaggregation is performed. The draft forecasts of the collection (or consolidated warehouses stock item) being forecast are disaggregated down through all levels until, finally, the MRP forecasts for the SKUs at the lowest level are updated. The calendar that applies to the selected entry applies throughout the levels when disaggregating and updating. Disaggregation occurs by starting with the collection instance being processed and processing each level going down through the hierarchy as follows:
At the SKU level the same processing occurs as in standard forecasting and the MRP forecasts are updated. The following process is performed (according to your selections):

-
When a SKU or consolidated warehouse item is deleted from a collection, the last aggregation date and time for the collection and its parent collection(s) up through all levels to the All Collections collection are reset to zero.
This forces you to re-aggregate the sales before demand history maintenance or forecasting can be performed.
-
Deleting SKUs and collections from the Collection Structure tree view does not delete the history for the SKUs from file. When you remove an SKU from a collection, the resultant suggested forecast for the collection changes.
-
When you delete a collection, only the instance of the collection is deleted: the collection descriptor (Browse on Collection Descriptors) is not deleted. When a collection instance is removed, anything contained in the collection (sub-collections or SKUs) are deleted. In addition, all previous selections, aggregated sales, sales adjustments, forecasts, collection warehouse lists, consolidate warehouse sales, consolidated sales adjustments and consolidated draft forecasts are removed from the families and groupings forecasting tables/files.
-
When you add stock items to a collection, the last aggregation date and time for the collection and its parent collection(s) up through all levels to the All Collections collection is reset to zero. This forces you to re-aggregate the sales before demand history maintenance or forecasting can be performed.
If you enabled the Aggregation in Families and Groupings setup option (Inventory Optimization - General Setup) then you are prompted to perform the sales aggregation whenever you add or delete an SKU, a consolidated warehouse item or a sub-collection in any collection or when you maintain sales adjustments or adjust for outliers.
Running the IO Purge and Update program will also perform the aggregation for you if an update is needed.
You can aggregate any collection, including the top level All Collections collection.
-
The Six Period Weighted Average and Twelve Period Weighted Average algorithms are not applied when insufficient history is available. In this case, the forecast calculation tries to use the default forecast algorithm if it differs, otherwise it reverts to using the Competition algorithm to calculate the forecasts.
