Subsequent / re-activation of Cost of Sales Accounting
We are currently engaged at a new SAP customer (ECC6) that does not currently require COS Accounting to be activated /functional area functionality, but might require it at a later stage / subsequent to the initial go-live.
Based on the contents of SAP Note 740519, it appears that when COS Accounting is subsequently activated, the functional area cannot be repopulated for historic data when using ECC6.
Should the customer decide to subsequently activate COS Accounting at the start of a new fiscal year (i.e. post go-live), all the P&L data will be populated with the functional area from the start of the new fiscal year. However, what about the carry forward balances for the Balance Sheet accounts? Is there a way to repopulate the "carried forward" balances in the Balance Sheet with a functional area, else the balance sheet will always contain incomplete functional area data for the carried forward balances.
Also, please advise if there is a program available to repopulate functional areas subsequently in the event of a subsequent activation of COS Accounting. If not, if the customer activate COS Accounting even though they don't require it at present, because it appears that you cannot change the functional area assignments once updated with transactional data?
As such, what is the recommended course of action:
1. Only activate COS Accounting when required, but resulting issues with updating historic data with functional area.... OR
2. Activate and configure pre go-live, but then cannot change functional area assignments once populated with transactional data.
I look forward to hearing from you.
