• What is the cause and solution for SAP error message /SCWM/CCHECK526 - Act. &4 of TU &3 is closed but act. &2 of door &1 is still open ?

  The SAP error message /SCWM/CCHECK526 indicates that there is a discrepancy in the status of transportation units (TUs) in the Extended Warehouse Management (EWM) module. Specifically, the error states that an activity (Act. &4) of a transportation unit (TU &3) is closed, but another activity (Act. &2) of the same door (Door &1) is still open. This situation typically arises during the process of handling transportation units, such as during loading or unloading operations.
  Cause:
  
  Inconsistent Status: The primary cause of this error is that the system has detected an inconsistency between the status of the transportation unit and the activities associated with it. For example, if a loading activity is marked as completed, but the unloading activity is still open, the system will raise this error.
  Manual Interventions: Manual changes or interventions in the system that do not properly update the status of the transportation unit can lead to this error.
  System Configuration Issues: Incorrect configuration in the EWM settings related to transportation units and their activities can also lead to this error.
  
  Solution:
  
  Check Activity Status: Review the status of the transportation unit and the associated activities. Ensure that all activities related to the transportation unit are correctly updated and closed as necessary.
  Close Open Activities: If there are any open activities that should be closed, complete those activities in the system. This may involve confirming the unloading or loading process.
  Reprocess the Transportation Unit: If the status is still inconsistent, you may need to reprocess the transportation unit. This could involve canceling and recreating the transportation unit or redoing the relevant activities.
  Consult Logs: Check the system logs for any additional error messages or warnings that may provide more context about the issue.
  System Configuration Review: If the issue persists, review the system configuration related to transportation units and activities to ensure that everything is set up correctly.
