Option Description
Update

Calculates the minimum quantity of a stock item required and updates the Minimum quantity field against the warehouse if lead time is defined against the stock item (Stock Codes).

Update and Report Calculates the minimum quantity of a stock item required and updates the Minimum quantity field against the warehouse. It also produces a report indicating those items where the minimum quantity exceeds the maximum quantity for the warehouse.
Report only Calculates the minimum quantity of a stock item required and updates the Minimum quantity field against the warehouse providing this will not make the minimum quantity more than the maximum quantity (i.e. if the minimum quantity is not greater than the maximum quantity, then the update takes place).

A report is produced which lists those items where the minimum quantity would exceed the maximum quantity for the warehouse.

After processing completed

These options are displayed within programs that can be automated. They enable you to indicate the action you want to perform once processing is complete (see Automation Design).

Report

This pane displays the results of the processing function you selected once processing is complete (unless you selected the option to close the application from the After processing completed section).

Calculation details

The calculation establishes the average quantity of a stock item sold over the last 12 months. It then multiplies this figure by the number of months required for an order of the stock item to be supplied.

The minimum quantity calculation is performed as follows:

((annual usage value / unit cost) / number of months' history) x (lead time / 30)

  • The annual usage value is divided by the unit cost to obtain the annual usage quantity (i.e. usage quantity = annual usage value / unit cost).
  • The annual usage quantity is divided by the number of months' history to establish an average monthly usage (i.e. average monthly usage = usage quantity / number of months' history).

    [Note]

    The number of months' history is stored against the warehouse in which the item is stocked. From the time of capturing the item, this number is incremented by 1 after each inventory month end, until it reaches a value of 12. This enables the calculation to cater for items that have been stocked for less than 12 months.

  • The lead time held against the stock item is divided by 30 and multiplied by the average monthly usage (i.e. inventory minimum quantity = (lead time / 30) x average monthly usage).

Notes and warnings

Restrictions and limits

  • The calculation is only applicable to stock codes with a usage history of two or more months.
  • The calculation is not performed for stock items where the current inventory cost is zero.
  • The results produced by this program will be inaccurate if there have been fluctuations in the costing of your stock items over the year.
