• What is the cause and solution for SAP error message PU190 - Post-import methods called without unique client ?

  The SAP error message PU190, which states "Post-import methods called without unique client," typically occurs during the import of transport requests in SAP systems. This error indicates that the system is trying to execute post-import methods that require a unique client context, but the current client context is not unique or is ambiguous.
  Cause:
  
  Multiple Clients: The error often arises when the transport request is being imported into a system that has multiple clients, and the post-import methods are not able to determine which client to apply the changes to.
  Transport Request Configuration: The transport request may have been configured in a way that does not specify a unique client for the post-import methods.
  Custom Code: If there are custom post-import methods defined in the transport request, they may not be handling client-specific logic correctly.
  
  Solution:
  
  Check Client Context: Ensure that you are importing the transport request into a specific client. If you are using a transport directory, make sure that the client is specified correctly.
  Review Post-Import Methods: If you have custom post-import methods, review the code to ensure that it correctly handles client-specific logic. You may need to modify the methods to ensure they can operate in a multi-client environment.
  Use Transaction STMS: Use the Transport Management System (STMS) to import the transport request. This tool is designed to handle client-specific imports and may help avoid this error.
  Import in a Single Client: If possible, try importing the transport request in a single client environment to see if the error persists. This can help isolate the issue.
  Check Transport Logs: Review the transport logs for any additional error messages or warnings that may provide more context about the issue.
