The criteria requirements category and target period are only used for period splitting That means for carrying out presizing for periods based on categories and versions.

You can select materials or product groups to be transferred or you can select according to the AFS requirements category. Category selection only applies to the presizing period splitting function and not the transfer to AFS demand management.

You must first transfer data into AFS Demand Management before you can carry out period splitting. Period splitting has the same effect as manually carrying out presizing to split periods in planned independent requirement maintenance, except that you can select the materials for this function based on the same criteria as for the transfer.
