In A7.3, can I edit the item master for non-stock item in sales order entry?

Hello Community,

In E1, I can set the attributes of the line type to edit the item master for a non-stock item number.  That way, the user cannot enter free-form text in the item number field in sales order entry.

However, in World A7.3, the line type program P40205 does not have an attribute for editing the item master.

So I tried the following:

I created a non-stock line type "NN" and I made it just like line type N, except that I changed the G/L class code, and I changed the inventory interface to "D".

I created a non-stock item in P4101 with line type NN. I did not create any branch plant record.
