Requirement:
The financial manager will prepare what to pay next month. The user assigned for payment will be restricted to pay only up to the prepared amount. After this amount, the user will get error message and cannot proceed.

Is there exist anything like the above in E1 8.12. It is a kind of budgeting, but I guess, it is better to create a small application to import the prepared excel sheet to JDE custom table ( it will have supplier number, amount, period etc.) . In the payment application (P0413M), when the user create payment, I will check against the custom table.
