Below is the scenario we need clarification

1. Invoice Created with 2 Lines having line Requester field for each line

Line1 with Requester- E1

Line2 with Requester- E2

Line1 has to go to approvals to E1A->E1B

Line2 has to go to approvals to E2A->E2B

simultaneously notification has to be sent E1A and E2A rather than waiting to complete approvals for Line1(E1A and E2A both approve).
