Error AA662 in Asset accounting after upgrade to ECC 6
After upgrade to ECC6 from R3 Enterprise, when we try to browse an asset, using transaction code AW01N, and go to posted values/Comparisons tab we get the following error:
SYST: You cannot change the depreciation periods Message no. AA662 Asset affected: 000000003983-0000 Diagnosis Processing terminated because the number of depreciation periods in company code 1100 has been changed. However, you cannot change the number of periods in your live (productive) system. Procedure Change the depreciation periods back to the original value in company code 1100. The number of depreciation periods is determined by the fiscal year version and the use of half-periods. At least one of these parameters was changed. If you want to change your system so that you can now work with half-periods, you have to use depreciation keys with time-dependent period control in that company code. If you need to make general changes to the number of periods for calculating depreciation per fiscal year, you will have to consult your system administrator.
We were not getting this error in R3 enterprise. We have tried implementing sap note 1009699 but it does not resolve the issue. What we observed is, AA662 occurs if you change the number of period in the fiscal year version or the use of half-periods, after you have already posted to assets. The most common cause is a different value in field ANLB-PERFY which is the number of periods in the fiscal year. If the number entered here does not correspond to the number of posting periods of the fiscal year used, the system raises error AA662 (except for none posted areas for which ANLB-PERFY = 000 or areas with depreciation to the date for which ANLB-PERFY = 365). For us there are many assets with ANLB-PERFY=24.
Is there a way to fix this problem by some config change or data fix. If any of you have come across a similar issue or have any insights on the same, please respond back.
