• What is the cause and solution for SAP error message /SCWM/LM_EPD000 - Performance document &1 is already being processed by user &2 ?

  The SAP error message /SCWM/LM_EPD000 Performance document &1 is already being processed by user &2 typically occurs in the context of the Extended Warehouse Management (EWM) module when a performance document (such as a handling unit, transfer order, or other warehouse-related documents) is being accessed or modified by multiple users simultaneously. This can lead to conflicts and inconsistencies in data processing.
  Cause:
  
  Concurrent Access: The primary cause of this error is that the performance document identified by &1 is already being processed by another user identified by &2. This can happen if two users attempt to edit or process the same document at the same time.
  Session Locking: SAP uses locking mechanisms to prevent data inconsistencies. If a user has opened a document and has not yet completed their transaction, the document is locked for other users.
  Long Processing Times: If a user takes a long time to process a document, it can lead to other users being unable to access it until the first user completes their task.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish processing the document. Once the document is released, you can try to access it again.
  Check Active Sessions: If you have access to transaction codes like SM12 (to check for locks) or SM21 (to check system logs), you can identify if the document is indeed locked and by which user. If necessary, you can contact the user to coordinate access.
  Communicate with Users: If multiple users are working on the same documents frequently, it may be beneficial to establish a communication protocol to avoid conflicts.
  Review Process Design: If this issue occurs frequently, consider reviewing the process design to minimize concurrent access to the same documents. This might involve changing how tasks are assigned or processed in the warehouse.
  System Configuration: In some cases, it may be necessary to review the system configuration or settings related to document processing and locking mechanisms. Consult with your SAP Basis or EWM consultant for further assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 for lock entries, SM21 for system logs, and SLG1 for application logs to troubleshoot further.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions to common problems.
  User Training: Ensure that users are trained on how to properly handle performance documents to minimize the chances of concurrent processing issues.
  
  If the problem persists after trying the above solutions, it may be necessary to escalate the issue to your SAP support team for further investigation.
