gATP process for Sales Order BOM
In gATP process, how is the ATP check carried for the follwoing scenario:
A material exists with a BOM. However parent material is NOT forecasted & planned but
ONLY components are forecatsed in DP and planned in SNP.
Now when a SO is entered against the parent material, how is the ATP check carried out? Does the ATP check for the supply situation of all the BOM components and any phantom BOM's for any of these BOM components?
