• What is the cause and solution for SAP error message UJA_EXCEPTION220 - Base member '&1' cannot be the parent of '&2' in PARENTH&3 ?

  The SAP error message UJA_EXCEPTION220 indicates a problem with the hierarchy structure in a planning or consolidation application, specifically in the context of SAP BPC (Business Planning and Consolidation) or SAP BW (Business Warehouse). The error message states that a base member (the first member) cannot be the parent of another member (the second member) in the specified hierarchy (the third member).
  Cause:
  
  
  Hierarchy Structure Violation: The error typically arises when there is an attempt to create or modify a hierarchy where the parent-child relationship is not valid. This could be due to:
  
  The base member being defined incorrectly.
  The base member already having a different parent.
  Circular references in the hierarchy.
  Incorrectly defined properties or attributes of the members involved.
  
  
  
  Data Integrity Issues: If the data model has been altered (e.g., members added or removed) without proper updates to the hierarchy, it can lead to inconsistencies.
  
  
  Solution:
  
  
  Check Hierarchy Definitions: Review the hierarchy definitions in the application. Ensure that the base member is correctly defined and that it is appropriate for it to be a parent of the specified child member.
  
  
  Validate Member Properties: Ensure that the properties of both the base member and the child member are correctly set. This includes checking for any attributes that might restrict the relationship.
  
  
  Review Data Model Changes: If there have been recent changes to the data model, ensure that all hierarchies have been updated accordingly. This may involve reassigning members or redefining relationships.
  
  
  Use Transaction Codes: If you are using SAP BW, you can use transaction codes like RSRT to check the hierarchy or RSD1 to manage InfoObjects and their hierarchies.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing hierarchies in your version of SAP BPC or BW.
  
  
  Testing: After making changes, test the hierarchy to ensure that the error does not reoccur. This may involve running reports or simulations that utilize the hierarchy.
