Setup parallel approval for Purchasing

Hi Team,

I need assistance with configuring the PO approval process as follows:

1. Parallel Approval: Either Person A, Person B, or Person C can approve – Once one of them approves, it should move to the next step.
2. Parallel Approval: Either Person A or Person B can approve – Once one of them approves, it should move to the next step.
3. Serial Approval: Person A must approve. Once Person A approves, it should move to the next step.
4. Parallel Approval: Either Person A or Person B can approve – Once one of them approves, it should move to the next step.
5. Serial Approval
