An Overview of Lot Sizes 
An Overview of Lot Sizes
Use
The maintenance of the lot-sizing procedures in AFS is based on the procedure you already know from the SAP standard as well as on procedures developed especially for AFS. You can use periodic and statistical lot-sizing procedures in AFS. Combined with other functions of the AFS MRP, lot-sizing procedures can have different effects (see
Lot Sizes in MRP).Features
In AFS the lot sizes are calculated using default quantities from the respective material master record or by combining requirement quantities of one or several periods to one lot size. This is valid for both the SAP lot-sizing procedures you use in AFS as well as for the lot-sizing procedures that are especially developed for AFS. You can maintain lot sizes both at material level and at SKU level. Note that this can lead to inconsistencies.
The following lot-sizing procedures are supported by AFS.
