The WIP Allocations by Cost Object documents with the Allocation of Fixed Asset Depreciation Costs transaction type are used for allocating the depreciation costs calculated at the month end and posted to the WIP GL accounts.
For allocating the depreciation costs, on the Sources tab, you can select the source document, Depreciation, and set the criteria for source of costs: specific departments, non-current asset classes, and particular fixed assets. On the Allocation Base tab, you can set the allocation coefficients for Cost Objects involved. Then on the Allocation tab, you can review the costs matching the specified criteria and click the Fill and Allocate button to distribute the depreciation costs between Cost Objects.
