• What is the cause and solution for SAP error message /SCWM/WAVE_PLAN021 - Wave picking start time is greater than the pick completion time ?

  The SAP error message /SCWM/WAVE_PLAN021 indicates that there is a discrepancy in the timing of wave picking operations. Specifically, it means that the start time for wave picking is set to be later than the completion time for picking, which is logically inconsistent. This can occur in the context of warehouse management and wave planning in SAP Extended Warehouse Management (EWM).
  Cause:
  
  Incorrect Time Settings: The start time for the wave picking might have been incorrectly configured or calculated, leading to it being set after the completion time.
  Data Entry Errors: Manual entry errors during the creation or modification of wave picking plans can lead to incorrect timestamps.
  System Configuration Issues: There may be issues with the configuration of the wave picking process or the underlying system settings that govern time calculations.
  Time Zone Differences: If the system is set up to handle multiple time zones, discrepancies in time zone settings can lead to incorrect time calculations.
  
  Solution:
  
  Review Wave Picking Configuration: Check the configuration settings for wave picking in the SAP EWM system. Ensure that the start and completion times are set correctly.
  Adjust Time Settings: If the start time is indeed set incorrectly, adjust it to ensure it is earlier than the completion time.
  Check for Data Entry Errors: Review the entries made for the wave picking plan to ensure that there are no manual errors in the timestamps.
  Consult System Logs: Look into system logs or error logs to identify any underlying issues that may have caused the incorrect time settings.
  Test with Sample Data: Create a test wave picking scenario with controlled data to see if the issue persists. This can help isolate whether the problem is with specific data or a broader configuration issue.
  Contact SAP Support: If the issue cannot be resolved through the above steps, consider reaching out to SAP support for further assistance.
