Payment Amount Restriction

Hi,

we are using ACH payment. in the ACH payment we have a business scenario to restrict payment amount <250000 $

For Ex:

Vendor A having 3 invoices.

invoice 1 with 100,000 $

invoice 2 with 100,000 $

invoice 3 with   50,000$

Vendor B having 3 invoices

invoice 4 with 100,000 $

invoice 5 with   50,000$

While running payment process, PPR need to process only vendor B invoices. it should restrict payment for Vendor A.

please any one give me the  solution for his payment restriction.

Thanks,

Jay
