• What is the cause and solution for SAP error message RH235 - Hierarchy "&1" contains a recursion at node "&2/&3" ?

  The SAP error message RH235 indicates that there is a recursion in a hierarchy structure, specifically in the context of organizational management or similar hierarchical data structures. This error typically arises when a node in the hierarchy points back to itself, either directly or indirectly, creating a loop that the system cannot resolve.
  Cause:
  
  Direct Recursion: A node is directly linked to itself.
  Indirect Recursion: A node is linked to another node, which eventually links back to the original node, creating a cycle.
  Incorrect Hierarchy Configuration: The hierarchy may have been incorrectly set up, leading to circular references.
  Data Migration Issues: If data has been migrated from another system, it may have introduced inconsistencies or errors in the hierarchy.
  
  Solution:
  
  
  Identify the Recursion:
  
  Use transaction codes like PPOME (for organizational management) to visualize the hierarchy and identify the nodes involved in the recursion.
  Check the hierarchy structure for any circular references.
  
  
  
  Correct the Hierarchy:
  
  Modify the hierarchy to remove the circular reference. This may involve changing the relationships between nodes or restructuring the hierarchy.
  Ensure that each node points to a valid parent without creating loops.
  
  
  
  Data Validation:
  
  If the hierarchy was imported or migrated, validate the data to ensure that it adheres to the expected structure without circular references.
  Use tools or scripts to check for and eliminate any recursive relationships.
  
  
  
  Testing:
  
  After making changes, test the hierarchy to ensure that the error no longer occurs and that the hierarchy functions as expected.
  
  
  
  Documentation:
  
  Document the changes made to the hierarchy for future reference and to prevent similar issues from arising.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PPOME, PPOSE, or OOSB for managing organizational structures.
  SAP Notes: Check SAP Notes for any known issues or patches related to hierarchy management.
  Best Practices: Follow best practices for hierarchy design to avoid recursion, such as clearly defining parent-child relationships and regularly reviewing the hierarchy for inconsistencies.
  
  By addressing the root cause of the recursion and ensuring proper hierarchy management, you can resolve the RH235 error and maintain a stable organizational structure in SAP.
