This is the default account to which the value of work in progress is posted when a job is created, if a work in progress account has not been assigned to the stock item for which the job is being created. The ledger code defined in the Capex in Progress field is used for all jobs created for and linked to a capex requisition line.

This is the account to which postings are made during the Backflushing function of the Inventory Movements program if there is a variance between the entered cost of the manufactured item and the cost of the item's material and labor allocations calculated by the system.

If you're using standard costing, then this is the default account to which WIP variances (falling below your specified value) are posted automatically when receiving a finished part into stock from a completed job. The account is only used if the Automatically cleared variance account is not defined against the warehouse.

If WIP inspection is required, then this is the default account to which the WIP value of goods received into inspection is posted. The account is used if a WIP inspection account is not held against the warehouse into which the goods are being received. You can't receive items from inspection into stock using the WIP Inspection Maintenance program if you haven't defined a WIP inspection account here or against the warehouse and you didn't enable the Request ledger code at transactions option.
