php - NetSuite - add custom lines to purchase order -

i want add custom lines, po lines, po object. parent of these custom lines should po. want display them po lines (in separate block).

you can create custom record called po lines. first field need "parent po" (choose own name) of type transaction , field should checked parent. add other fields desire custom lines

you need build subtab , use record.

you haven't mentioned how these lines create so: if user creation make sure intended audience has necessary privileges create & edit of new record if script creation, set parent po whatever po want on based on business logic
