  The SAP error message /SCWM/LM_CORE_APPL063 indicates that an external process step is already assigned to a labor activity. This typically occurs in the context of warehouse management, particularly when using the SAP Extended Warehouse Management (EWM) module.
  Cause:
  The error is triggered when:
  
  An attempt is made to assign an external process step (like a task or activity) to a labor activity that is already in use or assigned to another task.
  There may be a conflict in the system where the same process step is being processed simultaneously by different labor activities.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Current Assignments:
  
  Review the labor activities currently assigned to the external process step. You can do this by navigating to the relevant transaction or using the appropriate reports in SAP EWM to see the status of labor activities.
  
  
  
  Release or Reassign:

  Review Process Logic:
  
  Ensure that your process logic does not inadvertently try to assign the same step to multiple activities. This may involve reviewing the configuration or the custom logic in your warehouse processes.
  
  
  
  Check for System Errors:
  
  Sometimes, system errors or inconsistencies can lead to this issue. Check for any system logs or error messages that might provide additional context.
