Validities Using Cross-Location Validity Data 

Use

This function determines the validity start date and the validity end date for a substitute product using the cross-location validity data from the product and location interchangeability master data (interchangeability master data). The system determines or calculates these validities by converting the following information from the interchangeability master data:

●     Valid-from date

●     Use-up strategy

●     Use-up date

The conversion of the information from the interchangeability master data is necessary for generating a list with substitute products. Information about the validity of the interchangeability relationship between a predecessor and a successor product is defined in the interchangeability master data. The rules-based ATP check, on the other hand, requires information about the validity of one substitute product.

Prerequisites

●     In the master data for interchangeability, you have chosen the Use Cross-Location Validity Data value for the validity in a product substitution procedure.

●     You have made all the settings in the interchangeability master data and in integrated rule maintenance. For more information, see Substitutions from Master Data (with Condition Technique).

Features

In the master data, the following values determine the validity period for substitutions:

●     Valid-from date

This value specifies the date from which the substitution is valid.

●     Use-up strategy

The use-up strategy specifies the procedure for dealing with the stock of the valid product. The following use-up strategies exist:

○     Yes (Use up stock)

○     No (Do not use up stock)

○     Restricted (Use up stock depending on use-up date)

●     Use-up date

This value specifies the date until which the old product can be used. The use-up date is independent of the valid-from date.

The system uses this information to determine or calculate the validity start date or validity end date for the substitution of a predecessor product by a successor product.

Activities

The system determines or calculates the validity start date and the validity end date for the substitution of a predecessor product P1 by a successor product P2, as follows:

●     Validity start date for P1

The system does not determine a validity start date for P1. P1 is always valid.

The system only determines a validity start date for P1 if you have defined a substitution with the replacement type zero-to-one substitution for P1 in Customizing for the interchangeability master data. For more information, see the Implementation Guide (IMG) for SAP SCM under Advanced Planning and Optimization → Master Data → Product and Location Interchangeability → Application Settings → Maintain Replacement Types.

●     Validity start date for P2

The validity start date for P2 corresponds to the valid-from date of the interchangeability relationship.

●     Validity end date for P1

The system reads or calculates the date for the validity end date of P1 depending on the use-up strategy.

○     Yes (Use up stock)

If you have specified this use-up strategy, P1 does not have a validity end date. P1 is always valid.

○     No (Do not use up stock)

P1 is valid until the validity start date of P2.

○     Restricted (Use up stock depending on use-up date)

The use-up date corresponds to the date for the validity end date of P1.

●     Validity end date for P2

The system determines or calculates the date for the validity end date of P2 depending on whether P2 can be substituted by another product.

○     P2 is substituted by another product

The system determines or calculates the validity end date for P2 like the validity end date for P1.

○     P2 is not substituted

If P2 is not substituted by another product, P2 does not have a validity end date.

The system only determines a validity end date for P2 if you have defined a substitution with the replacement type one-to-zero substitution for P2 in Customizing for the interchangeability master data. For more information, see the Implementation Guide (IMG) for SAP SCM under Advanced Planning and Optimization → Master Data → Product and Location Interchangeability → Application Settings → Maintain Replacement Types.

Example

The following settings are defined in the interchangeability master data:

Predecessor Product	Successor Product	Valid-From Date	Use-Up Strategy	Use-Up Date
P1	P2	05.11.2004	No	-
P2	P3	01.12.2004	Yes	-
P3	P4	15.12.2004	Restricted	01.01.2005

The system calculates the following validities for the rules-based ATP check:

Product	Validity Start Date	Validity End Date
P1	-	04.11.2004
P2	05.11.2004	-
P3	01.12.2004	01.01.2005
P4	15.12.2004	-

The system does not determine a validity start date for P1. P1 is always valid. Since the use-up strategy No is selected for the interchangeability relationship between P1 and P2, P1 is valid until the valid-from date of the interchangeability relationship; in other words, it is valid up to and including November 4, 2004.

The validity start date for P2 corresponds to the valid-from date of the interchangeability relationship of P1 and P2. Since P2 is substituted by P3, the system calculates the validity end date of P2 depending on the use-up strategy of the interchangeability relationship between P2 and P3. Since the use-up strategy Yes is selected, P2 does not have a validity end date.

The validity start date for P3 corresponds to the valid-from date of the interchangeability relationship of P2 and P3. Since P3 is substituted by P4, the system calculates the validity end date of P3 depending on the use-up strategy of the interchangeability relationship between P3 and P4. Since the use-up strategy Restricted is selected, the validity-end date of P3 corresponds to the use-up date of the interchangeability relationship.

The validity start date for P4 corresponds to the valid-from date of the interchangeability relationship of P3 and P4. Since P4 is not substituted by another product, P4 does not have a validity end date.
