If you want to track specific stock item information for your business, you can create up to two code-type User-Defined Fields (UDFs) on the User-Defined Fields tab of the Module Preferences window. For example, you might want to track the row you store an item in the warehouse. You can type Row in one of the two Code fields (User-Defined Fields 1 and 2).

You can select Options > <Code Name> from the menu bar to access this UDF and define specific Codes to enter or select in those fields, such as ROW3A, ROW4C, etc.

You will then be able to attach the specific codes to individual stock items on the User-Defined tab of the IN Stock window.
