Best Practices: Adding totals to Item Tables

Can anyone suggest best practices for adding UOM and Currency totals to item tables?

I would like to add item totals to all customer facing documents in print format.

Why don’t use standard fields? There are already UOM and total field in the Item table. If you are using standard print format, you just need to remove those fields from “Print Hide”. In case of custom print format, you can use those fields in the code.
