The Data Element (DE) uuu_spa_per_comp (Percentage Complete to Date) is mandatory on the detail form of a Summary Payment Applications type Payment Application business process.
You can enter values in the detail form (grid) (for uuu_spa_per_comp (Percentage Complete to Date)) that is above 100 percent.
In the Summary Payment Application SOV structure, you can add a column with Datasource = Commits Remaining Balance.
If the Commits Remaining Balance column has not been added to the SOV structure, you will have the ability to overpay (assign a payment amount that exceeds the remaining balance and the uuu_spa_per_comp value exceeds 100%).
If the Commits Remaining Balance column has been added to the SOV structure, you will not have the ability to overpay (you will not be allowed to assign a payment amount that exceeds the remaining balance or to make the uuu_spa_per_comp greater than 100), and Unifier displays a detailed message notifying you that the payment amount exceeds the remaining reference commit balance.
