The processing of data at SKU level in purchase requisitions essentially corresponds to the procedure in all purchasing documents.

• Via you come to the SKU Overview screen from the item overview. Here you can specify purchase order quantities, the stock category, and the delivery date for each SKU. The system also displays the schedule line number and ordered quantities.
• Here you can round SKU values and specify quantities using a previously defined distribution profile ( presizing) just as you can in other purchasing documents. As long as you already determine a vendor in the purchase requisition, the rounding factor can be transferred from the purchasing info record or from the grid control data.

The source allocation supports you when you assign the optimal vendors to open purchase requisitions. By using Sort and Vendor Ranking Criteria you define the preferences that resulted from your business strategies and you specify which purchase requisitions will be assigned to a vendor first and which criteria should be considered during the assignment. After the assignment, the system writes the optimal vendors as fixed vendors in the purchase requisitions.

For the sake of quality, you can specify an AFS change reason code if you manually change a vendor in a purchase requisition.

• In purchase orders that are created with reference to a purchase requisition you can no longer manually change the SKU values specified in the purchase requisition. Here you can only modify quantities and category values.
• The R/3 standard functions Source list and Quota arrangement are not supported at SKU level.
