Hoping someone can give me some conceptual insight. I am trying to add the available quantity by location to the lines of a custom transaction. I don’t see any way to do this natively. Need these values updated when the transaction is viewed. (Basically just how a Sales Order works) My first thought was to create a search in a beforeLoad UE against the transaction, but struggling with how to map the results to the appropriate lines. Any thoughts? Thanks.

I think you can use UE before load on view and load record on view and edit field value and save the record. Consequently you can see results on view but bit slow.
