When working with item and entity records, NetSuite automatically switches the record to the preferred form, even if you initially create it using another form.
However, if you need the record to retain a specific non-preferred form, you can use the “Store Form with Record” checkbox available on the form. When this box is checked and the record is created using that form, NetSuite will save the record with that form and will not switch it back to the preferred form.
