Account AFFF-15001100 not allowed to be defined as reconciliation account
Message no. AC309
Diagnosis
Account 15001100 is defined as a reconciliation account for fixed assets for chart of accounts AFFF and account determination 11000. This is not correct in the circumstances (Contra account: Acquisition value posting).
Keep in mind that the Customizing definition of the given depreciation area also influences the consistency check of the G/L accounts. This is particularly true for the posting settings in the depreciation area, if the accounts are value adjustment (depreciation) accounts.
Procedure
Change the account definition, or assign a different account.
