I need someone who can explain a field in customizing for the ATP check
There is following possibilities
blank = Do not check
X = Include all reservations
A = Only include withdrawable reservations
Can anyone in simple words explain what is withdrawable reservations??
As I perceive:
If you create a production order you generate a reservation as well. This reservation is for the components you will consume when you book against your PrdOrd.
You can check these components: (menu) Goto > Overviews > Components (or there's an icon or you can push 'F6').
On the list you can find a column called 'Item no.' (struct: RESBD, field: RSPOS, it's not the first column!!!) - to each component belongs a reservation number.
SAP HELP says that you can withdraw (=backflushing) the reserved materials from WH if you released the operation to which they belong.
So there are withdrawable & not withdrawable reservations. Maybe in SCM-PP forum they can give you a better explanation.
