Payment Batch Approval Flow

Hello Team

We would like to request assistance in configuring an approval workflow for Payment Batches in our Oracle environment, following the rules outlined below:

First Approval Step:

The initial approval must always be performed by a fixed approver, e.g., Approver A.

This user will be solely responsible for the first validation of the batch.

Second Approval Step:

After the initial approval, the batch should be routed to a group of approvers.

The batch approval should be considered complete once any member of the group approves it (i.e., first-response approval logic).

How can we set up this approval flow in BPM?
