Summary:

Users would create requisitions, purchase orders with receipts, invoices, and work orders and forget to populate POET fields which then result for Projects to be understated.

Content (required):

The idea would be to require users to populate POET fields once, say, a certain account (CWIP 10700 in the business' case) is involved in the charge account combination. This would mean that they cannot submit source transactions for approval/creation when POET fields are unfilled while account 10700 is used in the charge account.
