Hi,
I have the business case that is:
1. Plant A purchse from plant B: delivery date is 21.08.2023 and committed date is 28.08.2023 after ATP

2. And Plant B create the PO to buy it from external vendor, because there is no stock, howerver the confrimation date is 14.09.2023

CO09:

My question is that:
The stock in plant B will be available at 18.09.2023 (14.09.2023+2 days GR), why the committed date in STO (plant A buy from plant B) is 28.08.2023, not 18.09.2023 (ShpgNt)
