Hello hello Dear Netsuite community. Very quick question. If you open a PO record, you can easily Go to Customize form and select the PRINT TEMPLATE. Why is this not available for a WO record-> print BOM. I cannot find which template is being used. Even if I create a new one, I wouldn't be able to select it for a WO.

you need to be editing the Transaction Form > Bill of Materials and set your Print Template there. Then on the Work Order customization, your linked form is the above "Bill of Materials" transaction form.
