• What is the cause and solution for SAP error message /SCWM/WAVE177 - Picking completion time is before picking start time ?

  The SAP error message /SCWM/WAVE177 Picking completion time is before picking start time typically occurs in the SAP Extended Warehouse Management (EWM) module. This error indicates that there is a discrepancy in the timestamps associated with the picking process. Specifically, it means that the system has detected that the completion time for a picking task is recorded as being earlier than the start time, which is logically inconsistent.
  Causes:
  
  Incorrect Time Stamps: The most common cause is that the timestamps for the picking start and completion are not being recorded correctly, possibly due to system clock issues or manual entry errors.
  System Configuration Issues: There may be configuration settings in the EWM system that are not aligned properly, leading to incorrect time calculations.
  Data Entry Errors: Manual entries or updates to the picking tasks may have been made incorrectly, resulting in the completion time being set before the start time.
  Time Zone Differences: If the system is set up to handle multiple time zones, discrepancies may arise if the time zone settings are not consistent across the system.
  
  Solutions:
  
  Check Time Stamps: Review the picking task in question to verify the recorded start and completion times. Ensure that the completion time is indeed after the start time.
  Correct Data Entry: If the timestamps are incorrect, update the picking task with the correct times. This may involve re-entering the data or using a transaction to adjust the timestamps.
  System Configuration Review: Check the configuration settings in the EWM system to ensure that they are set up correctly. This may involve consulting with your SAP Basis or EWM configuration team.
  Time Zone Settings: Ensure that the time zone settings are consistent across the system and that they are correctly configured for all users and processes.
  Consult SAP Notes: Look for any relevant SAP Notes or documentation that may address this specific error. SAP frequently updates its knowledge base with solutions for common issues.
