Availability Check

Availability Check

AC is determined by checking group and checking rule

Checking Group = A check+ Total Sales + Total Dlv Requirement + Block QtyRq + No Check + Accum
Av Check is defined in MRP3 in Material Master (Discussed below)
Total Sales = Single Records or Total Records per day or Total records per week
Total Dlv Rqs = Single Records or Total Records per day or Total records per week
Block QtyRq = This block is used if several users are able to process the material simultaneously in different transactions without blocking each other.
No Check = This indicator switches off the availability check according to ATP logic for the checking group concerned

Schedule Line and Requirement Type is determined by Item category and MRP Type

Following are the relevant fields required from Material Master to run Availability Check.

MRP1

MRP Type –PD

VB - We have to define, re-order point, safety stock etc. In manual reorder point, you must define the reorder point (and eventually the safety stock) according to your criteria. For automatic, these values are estimated by SAP as a function of the forecast (coming from historical data), so the base-quantities for the calculation of the reorder are not fixed but dynamic.

Lot Size – 10
