The SAP error message GK747 indicates that certain documents cannot be reversed in prior periods. This typically occurs in the context of financial accounting and controlling, where there are restrictions on reversing transactions that have already been posted in closed periods.
Cause: Period Closure: The most common cause of this error is that the financial period in which the documents were posted has been closed. SAP restricts changes to closed periods to maintain the integrity of financial reporting. Document Type Restrictions: Certain document types may have specific settings that prevent reversal in prior periods. Configuration Settings: The system may be configured to disallow reversals for specific accounts or transaction types in prior periods.
Solution: Open the Period: If you have the necessary authorizations, you can open the closed period in the financial settings. This allows for the reversal of the documents. However, this should be done with caution and typically requires approval from management or finance. Navigate
