create multiple STO outbound deliveries via allocation based on multiple inbound deliveries

Hello all,

We have a 2-step procurement scenario:

PO1 is from vendor to plant 1

PO2 is an STO from plant 1 to plant 2

We're using inbound deliveries. When we post GR on the inbound deliveries for PO1 we are then running VL10B in background to create outbound deliveries for PO2.

Our requirement is that we need to maintain a 1:1 relationship between inbound and outbound deliveries. So if PO1 item 10 is split across 2 inbound deliveries, we want to GR both deliveries, and then create 2 outbound deliveries based on allocation logic and the inventory created via the GR.

Thank you in advance for your help!
