• What is the cause and solution for SAP error message /SCWM/WAVE151 - No changes possible; delivery item &1 is assigned to more than one wave ?

  The SAP error message /SCWM/WAVE151 indicates that a delivery item is assigned to more than one wave, which prevents any changes from being made to that item. This situation typically arises in the context of warehouse management and wave management in SAP Extended Warehouse Management (EWM).
  Cause:
  
  Multiple Wave Assignments: The delivery item in question has been assigned to multiple waves. In SAP EWM, a delivery item can only be assigned to one wave at a time for processing. If it is assigned to more than one wave, the system will not allow changes to that item.
  Incorrect Wave Planning: There may be an issue with how waves are being planned or created, leading to overlapping assignments.
  Data Integrity Issues: There could be data integrity issues in the system, such as incorrect configurations or bugs that lead to multiple assignments.
  
  Solution:
  
  Check Wave Assignments: Review the wave assignments for the delivery item. You can do this by navigating to the wave management transaction in SAP EWM and checking which waves the delivery item is assigned to.
  Reassign Delivery Item: If the delivery item is indeed assigned to multiple waves, you will need to reassign it to a single wave. This may involve removing it from one of the waves.
  Adjust Wave Planning: Ensure that your wave planning process is set up correctly to prevent multiple assignments in the future. This may involve reviewing the criteria used for wave creation and ensuring they do not overlap.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on managing waves and delivery items in your version of SAP EWM.
  Contact Support: If the issue persists or if you suspect a bug, consider reaching out to SAP support for assistance.
  
  Related Information:

  By addressing the root cause of the error and following the suggested solutions, you should be able to resolve the issue and prevent it from occurring in the future.
