Today, when a user manually adds a component to an existing Production Order Line, the `Location Code` is left blank.

This leads to a lot of confusion, especially given that the `Location Code` is hidden, and users (correctly) assumes that all if well and fine.

When running a requisition worksheet, the added components end up in a blank location, and might not even be included if the user filters for a location when running the requisition worksheet.

Likewise, if the Component is flushed, an error occurs due to no inventory.

My suggestion is, that when validating the `Item No.`, that the `Location Code` is set to the `Location Code`, if the `Prod Order Component` has a blank Location Code.
