Hello! I searched in the documentation but I couldn't find anything final. The link between transaction and its advanced template using custom form is pretty straightforward for sales orders, invoices, cash sales and so on. The situation is far more complicated with item fulfillments and packing slips. Could anyone explain me how it works? Both in UI and inside scripts (for example in suitescript 1.0 I got different results using

html_file = nlapiPrintRecord("packingslip",73557,"PDF", null);

or

html_file = nlapiPrintRecord("transaction",73557,"PDF", null);

) Thanks in advance.

look on the linked forms subtab of the sales order form

Thanks 🙂
