• What is the cause and solution for SAP error message /SCWM/DLV_API014 - Method SAVE was already called in this LUW ?

  The SAP error message /SCWM/DLV_API014 Method SAVE was already called in this LUW typically occurs in the context of the SAP Extended Warehouse Management (EWM) module. This error indicates that the SAVE method of a particular function module or class has been invoked more than once within the same Logical Unit of Work (LUW). In SAP, an LUW is a sequence of operations that are treated as a single unit, and it is not permissible to call the SAVE method multiple times within the same LUW.
  Causes:
  
  
  Multiple SAVE Calls: The most common cause is that the SAVE method is being called multiple times in the same transaction or process. This can happen due to:
  
  Incorrect coding in custom ABAP programs or enhancements.
  Triggers or events that inadvertently call the SAVE method multiple times.
  
  
  
  Error Handling Logic: If there is an error handling mechanism that attempts to save data again after an initial save attempt, it can lead to this error.
  
  
  Concurrency Issues: In some cases, if multiple processes are trying to save data simultaneously, it may lead to this error.
  
  
  Solutions:
  
  
  Review Code: Check the custom code or enhancements where the SAVE method is being called. Ensure that it is only called once per LUW. You can use breakpoints or debugging to trace the flow of execution.
  
  
  Error Handling: If you have error handling logic that attempts to save again, modify it to avoid calling the SAVE method if it has already been executed.
  
  
  Use of Commit Work: Ensure that you are using COMMIT WORK appropriately. If you need to save data multiple times, consider breaking the operations into separate LUWs.
  
  
  Check for Triggers: If there are any event triggers or background processes that might be calling the SAVE method, review and adjust them accordingly.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific function module or class you are working with for any known issues or recommendations.
  
  
  Related Information:
  
  Transaction Codes: You may want to check transaction codes related to EWM, such as /SCWM/PRDI for inbound deliveries or /SCWM/ORD for outbound deliveries, depending on where the error occurs.
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that might address this specific error or provide patches or updates.
  Debugging: Use the ABAP debugger to step through the code and identify where the SAVE method is being called multiple times.
  
  If the issue persists after checking the above points, consider reaching out to SAP support or consulting with an experienced SAP EWM consultant for further assistance.
