Smart SAP Assistant

• What is the cause and solution for SAP error message /SCWM/LM_EWRKL150 - You cannot perform a mass change for EWLs with decreased actual duration ?

  The SAP error message /SCWM/LM_EWRKL150 indicates that you are attempting to perform a mass change on Handling Units (HUs) or Warehouse Tasks (WTs) in Extended Warehouse Management (EWM) where the actual duration of the EWLs (Execution Work Lists) has decreased. This situation typically arises when the system detects that the changes you are trying to apply would result in a conflict with the existing data, particularly regarding the actual duration of the tasks.
  Cause:
  
  Decreased Actual Duration: The error is triggered when the system identifies that the mass change operation would lead to a situation where the actual duration of the EWLs is reduced. This could happen if you are trying to change the status or attributes of tasks that have already been processed or partially processed.
  Data Integrity: SAP EWM has built-in checks to maintain data integrity and ensure that changes do not lead to inconsistencies in the warehouse operations.
  
  Solution:
  
  Review Changes: Before performing a mass change, review the changes you are attempting to make. Ensure that they do not involve reducing the actual duration of any EWLs.
  Adjust Duration: If you need to change the actual duration, consider adjusting it manually for each EWL instead of performing a mass change.
  Check Task Status: Ensure that the tasks you are trying to change are in a status that allows for mass changes. If they are already completed or partially processed, you may need to revert them to a status that allows changes.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on mass changes in EWM and the implications of changing actual durations.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide guidance based on your specific configuration and requirements.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on mass changes in EWM.
  Transaction Codes: Familiarize yourself with transaction codes related to EWM and mass changes, such as /SCWM/MASS_CHANGE or others that may be relevant to your operations.
  Training and Documentation: Ensure that users performing mass changes are adequately trained on the implications of such changes and the specific requirements of the EWM system.
  
  By following these steps, you should be able to address the error and perform the necessary changes in your SAP EWM system.
