• What is the cause and solution for SAP error message /SCWM/PS_BASICS220 - Recursion with subord. pack. specs results in a loop; saving canceled ?

  The SAP error message /SCWM/PS_BASICS220 indicates that there is a recursion issue with subordinate packaging specifications, which is causing a loop during the processing of packaging in the Extended Warehouse Management (EWM) module. This typically occurs when the system encounters a situation where packaging specifications reference each other in a circular manner, leading to an infinite loop.
  Cause:
  
  Circular References: The most common cause of this error is that the packaging specifications are set up in such a way that they reference each other, creating a loop. For example, Packaging Spec A references Packaging Spec B, and Packaging Spec B references Packaging Spec A.
  Incorrect Configuration: There may be incorrect or incomplete configuration in the packaging specifications that leads to this recursion.
  Data Integrity Issues: There could be issues with the data integrity in the packaging specifications, such as missing or incorrect entries.
  
  Solution:
  
  Review Packaging Specifications: Check the packaging specifications involved in the process. Look for any circular references and correct them. Ensure that each packaging specification is correctly defined and does not reference another specification in a way that creates a loop.
  Modify Specifications: If you find circular references, modify the specifications to eliminate the recursion. This may involve changing the hierarchy or the way packaging specifications are linked.
  Test Changes: After making changes, test the packaging process again to ensure that the error does not occur. Monitor the system for any further issues.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on setting up packaging specifications correctly.
  Seek Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance. They may have tools or insights to help diagnose and resolve the issue.
