Smart SAP Assistant

• What is the cause and solution for SAP error message /SCWM/HU_WM094 - PSHU &1 is being processed by another user; no creation possible ?

  The SAP error message /SCWM/HU_WM094 indicates that a Handling Unit (HU) is currently being processed by another user, which prevents any new operations or modifications from being performed on that HU. This is a common issue in systems where multiple users may be accessing and processing the same data simultaneously.
  Cause:
  
  Concurrent Access: The most common cause of this error is that another user is currently working on the same Handling Unit. This could be due to various operations such as picking, packing, or inventory management.
  Session Locking: SAP uses locking mechanisms to prevent data inconsistencies. If a user has opened a transaction that locks the HU, other users will be unable to perform actions on it until the lock is released.
  Long-running Transactions: If a user has a long-running transaction that involves the HU, it can lead to this error for other users trying to access the same HU.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to complete their transaction. Once the lock is released, you can try to process the HU again.
  Identify the Lock: If you have access to transaction codes like SM12 (to view locks) or SM21 (to check system logs), you can identify which user is holding the lock on the HU. This can help in understanding the situation better.
  Contact the User: If you identify the user who is holding the lock, you can reach out to them to see if they can complete their transaction or release the lock.
  Transaction Termination: If necessary and if you have the appropriate authorizations, you can terminate the session of the user holding the lock using transaction SM04 or SM12. However, this should be done with caution as it may lead to data inconsistencies.
  System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and user processes to minimize concurrent access issues.
  
  Related Information:
  
  Handling Units (HUs): In SAP Extended Warehouse Management (EWM), HUs are used to manage and track physical items in the warehouse. Understanding how HUs work can help in troubleshooting related issues.
  Lock Management: Familiarize yourself with SAP's locking mechanisms and how they work to better understand why certain errors occur.
  User Training: Ensure that users are trained on how to properly manage HUs and understand the implications of concurrent processing.
  
  If the problem persists despite following these steps, it may be necessary to consult with your SAP Basis team or technical support for further investigation.
