How To Fix PK178 - Kanban container &1 has been processed by another user

SAP Error Message - Details

• Message type: E = Error

• Message class: PK - Production - KANBAN

• Message number: 178

• Message text: Kanban container &1 has been processed by another user

What causes this issue?

The transaction to ensure that the KANBAN data are not blocked for a
long period of time, is as follows:
The data are read and can be processed by the user, but are not yet
blocked. Only when the changed data is to be saved are the data then
blocked. The actual status in the data base is then compared with the
data that was read in at the beginning.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

If the status of both of these sets of data are identical, your entries
will then be saved.
If, however, there are differences, it is probably due to another user
having changed the data in the meantime.

• What is the cause and solution for SAP error message PK178 - Kanban container &1 has been processed by another user ?

  The SAP error message PK178, which states "Kanban container &1 has been processed by another user," typically occurs in the context of the Kanban process within SAP's Production Planning (PP) module. This error indicates that the Kanban container you are trying to process is currently being accessed or has been modified by another user, leading to a conflict.
  Cause:
  
  Concurrent Access: Another user is currently processing the same Kanban container, which prevents you from making changes or processing it.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If one user is working on a Kanban container, it gets locked for others until the first user completes their action.
  Session Timeout: If a user has an open session that has not been properly closed, it may still hold a lock on the Kanban container.
  
  Solution:
  
  Wait and Retry: If another user is processing the Kanban container, wait for them to complete their task and then try again.
  Check User Sessions: Use transaction code SM12 to check for any active locks on the Kanban container. You can see which user is holding the lock and, if necessary, contact them to resolve the issue.
  Release Locks: If you have the necessary authorizations, you can manually release the lock from transaction SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still working on it.
  Review User Activity: Ensure that users are properly logging out of their sessions to avoid unnecessary locks.
  System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and user roles to ensure that they are set up correctly to minimize conflicts.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PK01 (Create Kanban), PK02 (Change Kanban), and PK03 (Display Kanban) for managing Kanban containers.
  User Training: Ensure that users are trained on the proper procedures for processing Kanban containers to minimize the chances of concurrent access issues.
  SAP Notes: Check for any relevant SAP Notes or updates that may address known issues related to Kanban processing and locking mechanisms.
