With regards to this issue, AU133 allways indicates missing
configuration in AO90.
1. Error AU133:
a) You have not defined a contra account for acquisition value
postings in the Asset Accounting Customizing settings (Transaction
AO90).However, this is required as of Release 4.6C because, as is
the case for all other integration postings in Asset Accounting,
invoice receipt postings have to be displayed in Asset Accounting
via the new posting kernel to ensure an identical document
structure.
b) You have defined the account in Asset Accounting, however, it is
not created in the affected company code.Check whether the account
is correct and create it for the company code, if necessary.
2. You have entered an asset reconciliation account for the "Contra
account: Acquisition value posting" (for example, the same account as
for the "Acquisition:Acquis. and production costs" account).This is
not permitted.Check whether your account determination is correct
(Transaction AO90) in Asset Accounting Customizing. The same applies
for the 'Contra account: Down payment posting'.
3. As "Contra account: Acquisition value posting" you entered an asset
G/L account. If necessary change the automatic posting indicator in
the G/L account master record.
4.Check if you need revaluation accounts in depreciation areas involved
(AO90):
-Revaluation acquis. and production costs
-Offsetting account: Revaluation APC
In addition, you can refer to the KBA 1572315 - Error AU 133 in RAPERB2000 / ASKB or RAPOST2000 / AFABN for detailed check.
