Definition of Validity Periods in Rules

Use

You use this function to define the period in which substitutions are valid.

The validity period in the rules is used, for example, for sales campaigns for products that are only to be offered for sale for a limited period of time.

Prerequisites

You have specified the validity period for substitutions in the product substitution procedure, location determination procedure or location product substitution procedure (procedures from rules-based ATP or from master data for interchangeability).

Activities

Global ATP evaluates the validity period of the product substitution procedure, location determination procedure, or location product substitution procedure. For the confirmation, the system only uses the stock and receipt elements that lie before the end of the validity period.

Note

If you want the system to also use stock and receipt elements that occur before the start of the validity period, define this in Customizing for the check instructions, in the Validity Mode field. For more information, see the Implementation Guide (IMG) for SAP Supply Chain Management (SAP SCM) under Advanced Planning and Optimization → Global Available-to-Promise (Global ATP) → General Settings → Maintain Check Instructions.

Example

A product substitution is only valid in the third quarter of 2002 (from 01.07.2002 until 30.09.2002). In Customizing for the Check Instructions, in the Validity Mode field, you have defined that the system can only use stock and receipt elements in the validity period. A requirement that is now created in the first quarter (02.02.2002) and whose requested delivery date is in the third quarter (08.08.2002), can only be confirmed if there are enough receipt elements available (that is, receipt elements that have not been reserved by other requirements) in the third quarter.

Warehouse stock, of which a sufficient quantity would be available on 02/02/2002, is not used for the confirmation. Since the warehouse stock is always checked using today’s date, it is not taken into account in this case, since the substitution is not valid at the time when the requirements element is being checked.

This applies not only to the stock but also to the planned receipt elements whose receipt dates lie before the start of the validity period.
