• What is the cause and solution for SAP error message /SCWM/WAVE031 - &1 is not a valid working day; wave completion date set to &2 ?

  The SAP error message /SCWM/WAVE031 &1 is not a valid working day; wave completion date set to &2 typically occurs in the SAP Extended Warehouse Management (EWM) module. This error indicates that the system is trying to process a wave (a group of tasks or orders) that has a completion date set to a day that is not recognized as a valid working day in the system's calendar.
  Cause:
  
  Non-Working Day: The date specified for wave completion falls on a non-working day (e.g., weekends, holidays) as defined in the factory calendar.
  Calendar Configuration: The factory calendar may not be properly configured, or the working days may not be set correctly.
  Wave Processing Logic: The logic used to determine the completion date of the wave may not account for non-working days.
  
  Solution:
  
  
  Check Factory Calendar:
  
  Go to the transaction code SCAL (Maintain Calendar) in SAP.
  Verify the factory calendar settings to ensure that the working days are correctly defined.
  Ensure that the date in question is marked as a working day.
  
  
  
  Adjust Wave Completion Date:
  
  If the wave completion date is set incorrectly, you may need to adjust it to a valid working day.
  This can often be done in the wave management screen or through the relevant transaction for wave processing.
  
  
  
  Review Wave Configuration:
  
  Check the configuration settings for wave processing in EWM to ensure that they are set up to handle non-working days appropriately.
  This may involve reviewing the settings in the Customizing (SPRO) for EWM.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to wave processing and factory calendar settings for any additional guidance or updates.

  SAP Notes: Check for any SAP Notes that may address known issues or provide patches related to wave processing and calendar settings.
  User Exits and BAdIs: If there are custom developments in your EWM system, review any user exits or BAdIs that may affect wave processing logic.
  
  By following these steps, you should be able to resolve the error and ensure that wave processing aligns with the defined working days in your SAP EWM system.
