Error AA478

Hi Gurus,

Please help me with this issue if you can,

The user set up a new asset with the correct asset class as previously the asset was created with wrong asset class but the depreciation was calculated on the old asset number.

And now the user is trying to reverse the depreciation posted with the Trans ABAA and transaction type 611

They are getting the error message

Posting transaction is not possible (value date not allowed)

Message no. AA478


A retirement was already posted on the asset 000003000988 0000 on 20090428. Based on the value date 20090423 of the transaction, this transaction should have been included in the calculation of values for the retirement.

System Response

The transaction is rejected.


Check the value date of the transaction.
