PK044 - Details

• The SAP error message PK044, which states "Data blocked by another user," typically occurs in the context of the Production Planning (PP) module when a user attempts to access or modify data that is currently locked by another user. This can happen in various scenarios, such as when trying to change a production order, a planned order, or any other object that requires exclusive access.
  
  Cause:
  
  Concurrent Access: Another user is currently editing or processing the same data object (e.g., production order, planned order).
