• What is the cause and solution for SAP error message /SCWM/IT_PRC_MD126 - Route &1 already exists ?

  The SAP error message /SCWM/IT_PRC_MD126 Route &1 already exists typically occurs in the context of SAP Extended Warehouse Management (EWM) when you are trying to create or modify a route that already exists in the system. This error indicates that the route you are attempting to create or update is already defined in the system, which prevents the operation from being completed.
  Cause:
  
  Duplicate Route Entry: The most common cause of this error is that the route you are trying to create or modify already exists in the system with the same identifier.
  Data Consistency Issues: There may be inconsistencies in the data, such as multiple entries for the same route due to previous imports or manual entries.
  Configuration Errors: Incorrect configuration settings in the EWM system can lead to attempts to create duplicate routes.
  
  Solution:
  
  
  Check Existing Routes: 
  
  Navigate to the route management area in SAP EWM and check if the route with the specified identifier already exists.
  Use transaction codes like /SCWM/ROUTE to view existing routes.
  
  
  
  Modify Existing Route: 
  
  If the route already exists and you need to make changes, consider modifying the existing route instead of creating a new one.
  Ensure that the changes you want to make are valid and do not conflict with existing configurations.
  
  
  
  Delete Duplicate Route: 
  
  If you find that there are duplicate entries that are not needed, you can delete the unnecessary route(s) to resolve the conflict.
