• What is the cause and solution for SAP error message KQ018 - Hierarchy & already summarized. No changes allowed ?

  The SAP error message KQ018 ("Hierarchy & already summarized. No changes allowed") typically occurs in the context of SAP Controlling (CO) when you are trying to make changes to a summarized hierarchy or a summarized version of a report. This error indicates that the hierarchy you are attempting to modify has already been summarized, and therefore, no further changes can be made to it.
  Cause:
  
  Summarized Hierarchy: The hierarchy you are trying to edit has already been summarized, meaning that it has been processed in a way that aggregates data, and changes to the underlying structure are not permitted.
  Data Integrity: SAP enforces this restriction to maintain data integrity and ensure that summarized data remains consistent and reliable.
  
  Solution:
  
  Check Hierarchy Level: Ensure that you are working on the correct level of the hierarchy. If you need to make changes, you may need to do so at a more detailed level before summarization.
  Un-summarize Data: If possible, you may need to un-summarize the data or revert to a previous state where changes can be made. This may involve using specific SAP transactions or tools designed for this purpose.
  Create a New Hierarchy: If changes are necessary and cannot be made to the existing hierarchy, consider creating a new hierarchy that reflects the desired structure.
  Consult Documentation: Review SAP documentation or help resources for specific instructions related to the hierarchy you are working with, as the steps may vary based on the version of SAP you are using.
