When MES is connected to XA environment and the Change Status button is in use, XA System Link is required to get full functionality.  


For Example: Changing status of an operation that is at status 20 in MOROUT to any other status requires System Link to be running and MES to be configured to utilize System Link.  The reason for this is that there is no XA PMC transaction to change the status only of an operation.  


MES can use System Link (if installed and running) to make Status changes to Operations.  


  • System Link Must Be running at the time the change status function is performed in MES WIP
  • MES must be configured to use system link.  By default, it is not.
    • MES Versions Prior to 5.4
      • WEB.Config file - 
        • <add key="UseMoroutForChangeStatus" value="false" />
        • by default the above setting is true and MES does NOT use system link
    • MES 5.4 and later
      • appsettings.config file - 
        • <add key="UseMoroutForChangeStatus" value="false" />
        • by default the above setting is true and MES does NOT use system link
