  The SAP error message WL138, which states "Import elements cannot be processed as a calling container is not defined," typically occurs in the context of Web Services or when working with Business Application Programming Interfaces (BAPIs) in SAP. This error indicates that the system is unable to process the import parameters of a function module or method because it lacks the necessary context or calling container.
  Causes:
  
  Missing Context: The calling container (like a Web Service or a specific context in which the function is being called) is not defined or is not available.
  Incorrect Configuration: The configuration of the Web Service or the BAPI might be incorrect, leading to the inability to identify the calling container.

  Check the Calling Context: Ensure that the calling context is properly defined. If you are calling a Web Service, verify that the service is correctly configured and that the necessary parameters are being passed.
  Review Function Module: Check the function module or method definition to ensure that all required import parameters are being provided and that they are correctly defined in the calling program.
  Debugging: Use the ABAP debugger to step through the code and identify where the context is lost or where the parameters are not being passed correctly.
  Configuration Review: If applicable, review the configuration settings for the Web Service or BAPI in transaction SOAMANAGER or the relevant configuration transaction.
  Check Transport Logs: If the issue arose after a transport, check the transport logs for any errors or inconsistencies that might have occurred during the transport process.
