How To Fix GL509 - Any changes made to the summarization can lead to consistency problems

SAP Error Message - Details

• Message type: E = Error

• Message class: GL - FI-SL Rollup

• Message number: 509

• Message text: Any changes made to the summarization can lead to consistency problems

What causes this issue?

Summarization &v1& has just been updated to &v2&.
If you change a summarization that has already been executed, this can
lead to data inconsistencies.
If you change the indicator 'Summarize the sender cost center by
level', new records might be written to the databank without updating
the old records and therefore unnecessarily increasing the amount of
data stored.

System Response

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

How to fix this error?

When you make such a change to a summarization, you should always check
whether or not the data marked with the option 'Delete all' should be
updated before the new execution of the summarization is to take place.
If you need to make several changes to the summarization definition,
you should consider if it would be wiser to create a new summariztion.
&NOTE&
You can receive information about previously processed summarizations
using the function 'History'.

  Solution:
  
  
  Review Changes: Before making any changes to summarization settings, review the current configuration and understand the implications of the changes. Ensure that no transactions have been posted that would be affected by the change.
  
  
  Revert Changes: If the error occurs after changes have been made, consider reverting to the previous summarization settings to restore consistency.
