Material availability check in production order

[Former Member]

Hi

When we check material availability during production order creation system checks and if the requirement is not fullfilled by the existing receipts then it gives missing part list. Here when I cheked the missing parts overview I get two fields one is confirmed qty and another is ATP qty. ATP qty I understand is nothing but the overall receipt qty and stock on the material reqmt day. Correct me if I am wrong.

I am using standatd 02-PP scope of check.

But what is Confirmed qty and on what basis system is calculation this figure? Everytime I change my reqmt and checks avaialibilty it gives a new confirmed qty.

Can anyone explain about this?

Thanks
