5P394 - Details

• The SAP error message 5P394 E: Return nodes are not allowed to have children typically occurs in the context of SAP Business Workflow or when dealing with certain data structures in SAP applications. This error indicates that a return node in a workflow or data structure is incorrectly configured to have child nodes, which is not permitted.
  
  Cause:

  Review Workflow Configuration:
  
  Open the workflow definition in the SAP Workflow Builder.
  Locate the return node that is causing the issue.
