ATP Substitution 

Use

It is occasionally necessary to allow substitution of one material for another within a sales order. This is due to inventory shortages resulting from higher than usual consumer demand, delays in the supply chain, phasing out of an old style or color, or other considerations. The ability to identify and substitute acceptable products in such situations helps to avoid lost sales and increases customer satisfaction with timely deliveries.

To define which materials may be substituted:

       1.      On the SAP Easy Access Screen, choose Logistics ® Sales and Distribution ® Master Data ® Products ® Material Determination.

       2.      Go to the Create Material Determination Initial Screen (transactions VB11/VB12 in the standard SAP system) and select a material determination type.

       3.      In the MatEntered column, enter the material number for which you want to allow substitutions (original SKU). Then in the Material column, enter the material number of the substitute (substitute SKU).

       4.      Save your entries.

During order pricing, the system recognizes whether a substitution has been made. The system checks the substitution control rule in Customizing to see whether the user must be given the price for the original material, the substitute material, or the lower of the two prices.

A contract call-off order can also trigger substitution. The substituted quantity is subtracted from the quantity of the originally ordered material item.
