Payment Approval(PPR) on the basis of supplier total instead batch total

Summary:

Currently, payment approvals are triggered at the payment batch level, and a single approval notification email is sent to the approver for the entire payment batch.

However, the business requirement is to initiate payment approvals based on the total invoice amount grouped by supplier within the payment batch.

Example:
Supplier ABC

• INV1: Rs. 2,000
• INV2: Rs. 5,000
  Total: Rs. 7,000

Supplier XYZ

• INV3: Rs. 3,000
  Total: Rs. 3,000

In this scenario, the expectation is that a separate payment approval request/email should be generated for Supplier ABC based on the aggregated payment amount of Rs. 7,000 (INV1 + INV2). Similarly, approvals should be evaluated independently for other suppliers based on their respective total invoice amounts.
