GOP is suggesting a wrong warehouse where there is no hand in other warehouse

Summary:

Setups and on hand Sourcing rule

ATP rule will supply chain availability search, and ATP assignment is at item

Global sourcing rule for transfer from Org AB is Rank 1 and Org CD is Rank2

Assignment Set is at item level and used the Global Sourcing rule above

On hand at the very first has 5 qty each in both orgs this is not back to back enabled item

Create order without giving any warehouse to see if which is is GOP picking automatically Org CD is picked (Not sure why as Rank is 2 is picked). Scheduled and reserved

Created further orders to deplete the remaining 4 qty
