Unplanned depreciation posted to AA only and not FI

Dear all,

In our Prod system, we have some unplanned depreciation which have been posted to AA only - thereby causing a difference between FI and AA. How do I remove this difference now? I have gone through the OSS note 69225 - Reconciliation difference financial/asset accounting - however, this does not solve our problem since the net effect when doing this transaction is 0.

If we do a journal entry via the transaction F-02 - Enter G/L Account Posting - this will do not be good since the unplanned depreciation run has already affected the P&L accounts. Therefore, while the balance sheet G/L account will be corrected, the P&L account will have been affected twice.

Can anyone help please? Also, can you indicate why this occurred in the first place so as to avoid it happening again in the future.

Thanks,

Nas
