Specifically, it states that there are no valid lanes or schedules available for the specified route from location &1 to location &2. This can occur for several reasons, and here are some potential causes, solutions, and related information:

  Missing Transportation Lanes: There may not be any defined transportation lanes between the two locations in the system.
  Inactive Transportation Lanes: The transportation lanes that exist may be inactive or not valid for the specified time frame.
  Scheduling Issues: There may be no valid schedules defined for the transportation lanes, meaning that even if a lane exists, there are no available transport options.
  Master Data Issues: There could be issues with the master data, such as incorrect or incomplete location data, which prevents the system from finding a valid path.
  Configuration Issues: The configuration settings in TMS may not be set up correctly, leading to the inability to find valid paths.
  
  Solutions:
  
  
  Check Transportation Lanes:
  
  Go to the TMS configuration and check if there are transportation lanes defined between the two locations.
