Credit Check - Open Order Amount

JDE E1 9.2

According to documentation, Open Order amount (P42050) exclude future-committed orders until the scheduled pick date (PDDJ) falls within the commitment days of the branch-plant (7 days in our env). PDDJ exists in order header and order lines. If order lines have different PDDJ, the PDDJ of the first line will be updated in the header's PDDJ. So, when JDE updates open order amount for credit check, does it depend on PDDJ on each line? or PDDJ on the order header?

Thanks.
