I have a custom record that has a parent / child relationship with a transaction. I noticed when I created the sublist in addition to the New button there was also an Attach button. What does this button actually do? I see I can find an entry from my the custom record that was created previously (in a different sales order and if I press the button that record belongs now to this sales order and its link to the other sales order is gone. Is there a way to have it link to both sales orders? Note that my record is parent field is one with the transaction number list.
