Substitutions from Master Data (With Condition Technique) 

Purpose

The rules-based ATP check uses this process to determine product substitutions and substitute locations for an input location product from the substitution procedures for the master data for product and location interchangeability (master data for interchangeability) instead of from the substitution procedures from integrated rule maintenance.

Prerequisites

You have defined one or more of the following procedures in the interchangeability master data:

●      Product substitution procedure (PSP)

●      Location determination procedure (LDP)

●      Location product substitution procedure (LPSP)

You have made the following settings in integrated rule maintenance:

●      You have specified the PSP, the LDP, or the LPSP that you defined in the interchangeability master data.

●      You have set a filter for replacement types from the interchangeability master data in the rule control, as required.

●      You have made all remaining settings for rules in integrated rule maintenance. For more information, see Creating Rules.

●      For product substitution procedures, you have specified which of the following data you want the system to use to determine the validities:

○       Cross-location validity data

○       Validity data for planning

●      If you want to use a location determination activity for location determinations, you have created one.

Process

...

       1.      The system performs a rules-based ATP check and determines one or more rules for which you have specified the name of a PSP, LDP, or LPSP from the interchangeability master data.

       2.      The system determines the substitutions from the PSP, the LDP, or the LPSP in the interchangeability master data.

       3.      The system determines the validities for each substitution. For more information, see Example for Determining Validities.

       4.      The system calculates quantity factors for the product substitutions for which you have defined a factor for the predecessor or for the successor quantity in the interchangeability master data. For more information, see Calculation of Quantity Factors for Product Substitutions.

       5.      The system determines a list with substitute products and substitute locations using the access strategy from rule control.

       6.      The system uses rule control to determine substitute location products.

       7.      The system determines a validity period for the substitute location product.

       8.      The system checks the availability of the requirement quantity for the substitute location products.
