Creating SC Purchase Requisitions and SC Orders 
Procedure
To create a purchase requisition or a purchase order in subcontracting, take the following steps:
- Flag the purchase requisition item or purchase order item as the subcontracting item by choosing the item category
L.
Enter the material and the quantity, choose 
, and enter the SKU data.
Since the type and quantity of the components to be provided are dependent on the SKUs of the finished product, you cannot enter subcontracting items at material level, but only at SKU level.
The listing of the components to be provided takes place either manually or via BOM explosion:
- If you have not defined a bill of material for the finished product, you go to the collective entry of the components to be provided after you have entered the SKU data. The field Grid value will display the grid value for which you enter components to be provided. After entering the materials for an SKU to be provided, navigate with Back to the component entry for the next SKU and in this manner, enter the components to be provided for each SKU sequentially.
- If you enter standard materials as components to be provided, enter the materials and requirements quantities of the components. If you enter AFS materials as components to be provided, you must also specify the SKUs of the material to be provided in the fields Grd val and Reqmt. category. The system calculates the requirements date of the components to be provided (delivery date of the subcontracting item minus the planned delivery time).
- If you have entered a purchase order item as the subcontracting item, you must specify components to be provided. You cannot leave the components processing until you have entered at least one component to be provided for each SKU.
- If you have defined exactly one
bill of material for the finished product, it will automatically be exploded after you have entered the SKUs for the finished product. The system calculates the required quantities and the requirements date of the individual components. BOM items can be subsequently added to or changed.
If you have defined several alternative bills of material for the finished product, it is not possible to select the desired bill of material interactively. You can control the selection only by using the following mechanisms:
- Selection according to quantity: A lot size interval for which the BOM is valid can be entered in the BOM header. You can only use this selection procedure if the indicator Selection method has not been set in the MRP 4 view of the material master.
- Selection according to date: You specify the validity of the various BOM alternatives in Customizing via Production ®
Basic Data ®
Bill of Material ®
Alternative Determination ®
Define alternative determination for multiple BOMs. You can only use this selection procedure if the value 1 has been entered in the field Selection method in the MRP 4 view of the material master.
- Selection according to production version: This selection procedure allows you to define different BOMs for the same material, dependent on the vendor. To do this, enter different production versions via the pushbutton ProdVersions in the MRP 4 view of the material master . You uniquely assign a BOM alternative to each of these production versions in the detail view. Then enter the production order valid for each in the info record.
If you create alternative BOMs without setting a selection mechanism, the system will explode in purchasing documents the first BOM it finds.
- Save your SC purchase requisition or SC order. Based on the entered quantities, the system creates dependent requirements and reservations for the corresponding components.
- To see the list of the components to be provided either from the SC purchase requisition or the SC order, select an SKU in the SKU overview and choose

Conversion of an SC Purchase Requisition to an SC Order
If you convert an SC purchase requisition to an SC order and by doing so decrease the purchase order quantity in the purchase order, the SC purchase requisition will still be flagged as completed. If you want to be able to create additional SC purchase orders up to the point the purchase requisition quantity is reached, set the indicator SC PR rem. open in Customizing (AFS ®
Materials Management ®
Global materials management settings).
