Issues in Price Break and subsequent steps missing

Situation

User  update unit price on BPA Lines/Price Breaks.

Once unit price updated on BPA Lines/Price Breaks, need to run retroactive price adjustment program to update unit price on releases based on need by date.

User needs to submit Create Adjusting Documents in Payables Program in Payables module to create Positive and Negative PO Price Adjustment invoices

Business Impact:

1. Supplier can be over or under Paid due to user directly update Unit price on BPA Lines/Price Breaks.
2. Other possible issues are that
   1. User directly update Unit price on BPA Lines and did not submit retroactive program.
   2. User directly update Unit price on BPA Lines and run retroactive price adjusting program.
