• What is the cause and solution for SAP error message RSRV144 - The hierarchy leaf &1 from type RESTLEAF is not unique ?

  The SAP error message RSRV144 indicates that there is a problem with the uniqueness of a hierarchy leaf in a reporting structure, specifically for a type called RESTLEAF. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with hierarchies in InfoObjects.
  Cause:
  The error occurs when the system detects that there are multiple entries (leaves) in a hierarchy that share the same key or identifier. In a hierarchy, each leaf node should be unique to ensure that the structure is valid and can be processed correctly. Non-unique leaves can lead to confusion in reporting and data analysis.
  Solution:
  To resolve the RSRV144 error, you can follow these steps:
  
  
  Identify Non-Unique Leaves:
  
  Use transaction code RSRV to access the Data Integrity Check tool.
  Enter the relevant InfoObject or hierarchy and execute the check to identify the specific leaves that are causing the issue.
  
  
  
  Review Hierarchy Structure:
  
  Go to the hierarchy maintenance transaction (e.g., RSH1 for Hierarchy Maintenance).
  Check the leaves of the hierarchy for duplicates. You may need to look at the properties of each leaf to determine why they are not unique.
  
  
  
  Correct Duplicates:
  
  If you find duplicate leaves, you can either:
  
  Remove the duplicates if they are not needed.
  Rename or modify the leaves to ensure that each one has a unique identifier.
  If necessary, adjust the hierarchy structure to reflect the correct relationships.
  
  
  
  
  
  Rebuild the Hierarchy:
  
  In some cases, it may be easier to delete the existing hierarchy and recreate it from scratch, ensuring that all leaves are unique.
  
  
  
  Recheck for Errors:
  
  After making the necessary changes, run the integrity check again in transaction RSRV to ensure that the error has been resolved.

  Documentation: Refer to SAP Help documentation for more details on managing hierarchies and InfoObjects in SAP BW/BI.
  
  
  Best Practices:
  
  Regularly check the integrity of your hierarchies to prevent issues from arising.
  Maintain clear naming conventions for hierarchy leaves to avoid confusion and potential duplicates.
  
  
  
  By following these steps, you should be able to resolve the RSRV144 error and ensure that your hierarchy structure is valid and functional.
