• What is the cause and solution for SAP error message 5P393 - E: Return nodes are not allowed to have children or siblings ?

  The SAP error message 5P393 E: Return nodes are not allowed to have children or siblings typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when dealing with message mappings or graphical mappings. This error indicates that a return node in your mapping is incorrectly structured, as return nodes are not permitted to have child nodes or sibling nodes.
  Cause:
  
  Incorrect Mapping Structure: The return node is designed to be a terminal node in the mapping structure. If you have added child nodes or sibling nodes to a return node, it violates the rules of the mapping structure.
  Misconfiguration in the Mapping: The mapping may have been configured incorrectly, leading to an invalid hierarchy where a return node is not properly isolated.
  
  Solution:
  
  Review the Mapping: Open the graphical mapping or message mapping where the error occurs. Check the structure of the return node.
  Remove Child/Sibling Nodes: Ensure that the return node does not have any child nodes or sibling nodes. If there are any, remove them to comply with the mapping rules.
  Validate the Mapping: After making the necessary adjustments, validate the mapping to ensure that it is correctly configured and does not produce any errors.
  Test the Mapping: Execute a test run of the mapping to confirm that the error has been resolved and that the mapping works as intended.
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or the specific documentation for SAP PI/PO for more details on message mappings and the structure of return nodes.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  Debugging Tools: Utilize SAP's debugging tools to trace the mapping execution and identify where the structure may be going wrong.
  
  By following these steps, you should be able to resolve the error and ensure that your mappings are correctly configured.
