How To Fix GU636 - Postings to &1 during the run may lead to incorrect results

SAP Error Message - Details

• Message type: E = Error

• Message class: GU - FI-SL utilities

• Message number: 636

• Message text: Postings to &1 during the run may lead to incorrect results

What causes this issue?

You want to perform a balance carryforward for ledger &V2&.
The system has determined that for the company code to be carried
forward &V3& at least, there are still open posting periods in the old
fiscal year &V1&. (Note that alongside company code &V3&, there may be
open posting periods for other company codes that are to be carried
forward. Please check whether this is the case.)
If postings are made to the old fiscal year when the balance is actively
carried forward, the results of the balance carryforward may be
incorrect.
Due to conceptional reasons and for performance reasons, the system is
unable to ensure that postings are not made to the old fiscal year when
the balance is actively carried forward.

System Response

A corresponding information message is issued (for the first affected
company code with open posting periods in the old year).

How to fix this error?

Make sure from an organizational perspective that when the balance is
actively carried forward, postings are not made to the old fiscal year
&V1& (for example, by temporarily closing the posting periods in the old
year or starting the balance carryforward in a posting-free period).
If postings are made to the old year, however, and the results of the
balance carryforward are incorrect, you can repeat the balance
carryforward at any time when postings are no longer made to the old
fiscal year. The results will then be correct.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message GU636 - Postings to &1 during the run may lead to incorrect results ?

  The SAP error message GU636 indicates that there are postings to a specific account (denoted by &1) during a run that may lead to incorrect results. This typically occurs in the context of financial postings, such as during the execution of a financial report, closing activities, or during the execution of a batch job.
  Cause:
  
  Concurrent Postings: The error often arises when there are concurrent postings to the same account while a financial run (like a closing run or report generation) is being processed. This can lead to inconsistencies in the data being reported or processed.
  Timing Issues: If the financial run is initiated while other transactions are being processed, it can result in a situation where the data being read is not consistent with the data being posted.
  Configuration Issues: There may be configuration settings in the system that allow postings to occur during critical financial processes, which can lead to this error.
  
  Solution:
  
  Check for Concurrent Postings: Before running the financial report or process, ensure that no other transactions are being posted to the same account. This may involve coordinating with other users or processes to avoid overlaps.
  Schedule Jobs Appropriately: If you are running batch jobs or financial reports, schedule them during off-peak hours when no other postings are expected.
  Locking Mechanisms: Implement locking mechanisms or use transaction codes that prevent postings during critical runs. This can help ensure data integrity.
  Review Configuration: Check the configuration settings in the SAP system to ensure that they are set up to prevent postings during critical financial processes.
  Consult Documentation: Refer to SAP documentation or notes related to this error message for any specific recommendations or patches that may address the issue.
