Answer 1

Hi,
During configuration of STO's, an availability check is assigned (IMG > MM > Purchasing > Purchase order > Set up Stock transport order > Assign delivery type and checking rule).
Because of this, during the creation of a STO, the system will perform an availability check for the material in the source plant. The results of this ATP are the two fields that you have mentioned. Zero in committed quantity means that the ATP check found no material available, according to the ATP check you have assigned, on the date you have proposed. A quantity less the entire quantity of the STO indicates that only a portion of the STO requirements was found to be available on the proposed date in the supplying plant.
Any time the committed quantity is less than the entire quantity of the STO, it means there is no assurance that there will be product available when the day comes to actually create the delivery note and PGI the STO.
Any time a requirement is not committed during an ATP check, the possibility also then exists that other requirements in the supplying plant (such as new sales orders, or new production order dependent requirements) may take stock that you intended for use in your STO. It is always wise (but not mandatory) to manipulate your STOs so that committed qty = delivery qty.
