Making Settings in the Master Data 
Use
As long as you determine your vendors in the AFS procurement process using the source allocation, you should make additional settings in the master data. These settings will be analyzed as evaluation criteria in the source allocation and will help you assign the optimal vendor to your open purchase requisitions.
Making Settings in the Material Master
In the material master, store a purchasing organization, which should be assigned to the automatically generated purchase requisitions, and activate a quota category.
Choose Logistics ® Materials Management ® Material Master ® Material ® Create ® ... / Change ® ... and then choose the Purchasing view.

Purchase requisitions that are not assigned a purchasing organization will be ignored in the source allocation.
Making Settings in the Vendor Master
Specify the factory status in the vendor master and decide whether different purchase requisitions are permitted to be grouped together for one vendor.
Choose Logistics ® Materials Management ® Purchasing ® Master Data ® Vendor ® Purchasing ® Create / Change, and then select Purchasing Data and choose Environment ®
AFS Additional Data.
During a source allocation, the system should first consider the vendors, with whom you have a very good relationship, such as partners. If your partner or preferred vendor cannot fulfill the purchase requisitions, a check is carried out and the purchase requisitions are assigned to other vendors if necessary.
Making Settings in the Purchasing Info Record
In the purchasing info record you specify the complexity factor and the capacity offset lead time.
