When you are posting a route card journal manually or through a production start process you could get an error when you have missed matched setup. For example if you have setup your route to not use setup time but the route group is setup to expect setup. Them you will get an error something to the effect of cost category for time not specified. It’s worth reviewing the setup and if there is a specific operation you don’t setup you might consider creating a specific route group for that.
Here is a quick overview.
