Hi,

We have below approval requirement, please guide on how this can be achieved.

Purchase orders with purchasing category "BioTech" will go to an approval group consisting of 3 people ( A, B, C), simultaneously.

Now out of A, B, C, whoever approves the PO first, the PO needs to be approved by their supervisor.

ie Say if A approves the PO, then the next approver will be A's Supervisor

If B approves the PO, then the next approver will be B's Supervisor

If C approvers the PO, then the next approver will be C's supervisor.
