How to validate record when user click go button on shipping transaction form.

Hi All,

I want to validate some records on shipping transaction form. Before launch pick release, user have to fill tracking number , seal_number and attribute1 on detail form. User only input those fields on 1 record although on the shipping transaction form there are more then one record. because I will update the record with pl/sql.

The issue is when user launch pick release and then click go button , if the record that user has input is backordered. I can not update the field because backordered item doesn't have move order number. So to overcome this issue I want add validation using form personalization , user can not closed the transaction form before he/she input required information to other item that not backordered.
