Subcontracted routing operations need to be completed. One can do this manually but much more convenient is to use the parameter in prod control or subcontract PO's. Upon receiving of such a PO, the subcon operation can be completed using a special route group. This set up is pretty subtle and the user can easily forget something .The system will never warn the user. The user is in a wide open situation without guidance THe idea is to add warning messages as follows -When the user switches the parameter for SUbcon PO's for routing card to "Route group dependent", perform the following checks for a production order that has a service item in its BOM with line type "vendor". During estimation check: -whether the route type = vendor -whether the route group for the subcon operation does indeed have the right checkboxes to flush the labor and complete the operation -whether the Service item in the PROd BOM is linked to the subcontract operation -whether the service item in the prod bom has a warehouse Four warnings can result from this in sequence of above: -:route type of subcon operation is not "vendor" -Route group of subcon operation does not have automatic consumption and completion checked -Subcontract service item not linked to subcontract routing operation -subcontract service item has no warehouse This would prevent a lot of grief.
