  Restricting the Number of Substitutions

Use

You can make settings to determine how many substitutions are allowed for the input location or the input location product until the requirement is covered.

Prerequisites

You have created a rule . This rule is inclusive.

Procedure

  1. On the SAP Easy Access screen, choose Start of the navigation path Advanced Planning and Optimization Next navigation step Master Data Next navigation step Rule Maintenance Next navigation step Integrated Rule Maintenance End of the navigation path .

  2. Choose ( maintain rule), select a rule and choose Enter .

    The individual data for the rule is displayed in the Details frame.

  3. Choose ( Change current rule ).

  4. Select the number of allowed substitutions for the input location product. There are only two possible entries:

    • No restrictions

      You can choose as many substitutions as required; that is, there are no restrictions. This is the standard setting.

    • Only one substitution

      Only one substitution can be chosen. The system selects the substitution that can deliver the full quantity first – if necessary, in a delivery proposal.

      If a substitution that can fill the complete quantity cannot be found, the system does not select a substitution. In this case, no quantity is confirmed.

      Using user exit EXIT_/SAPAPO/SAPLATPT_002 a substitution can be confirmed depending on the date. The user exit is called after the check. If the user exit is active, substitutions that were returned from the rules can be selected. Furthermore, the confirmation (date and quantity) can be changed. Several substitutions are possible. In the hierarchical display you can only select one substitution.

      For documentation on the user exit, see the Customizing of SAP APO under Start of the navigation path Global ATP Next navigation step Enhancements Next navigation step Choose Substitutions. End of the navigation path

      Note Note

      End of the note.

      If you allow one substitution only , at least one substitution procedure must be assigned to the rule. Otherwise the indicator is ignored.

      If you maintained the same locations with different location determination activities in a location determination procedure, the system can only interpret these as real substitute locations if the number of substitutions allowed is limited there.

  5. Select the entity for which the number of substitutions is valid. The following selection options exist for the entity:

    • Location product

      The number of substitutions is valid for the location product. This is the standard setting.

    • Location

      The number of substitutions is valid for the location.

    • Not defined

      The number of substitutions is valid for the entity that was defined in the previous rule. In the following cases, the value Not defined prevents the system from making any restrictions for the number and entity of substitutions:

      • The system has not found another rule by means of the rule strategy that is first evaluated.

      • The system has found another rule that is first evaluated. In this case, the entity is also set as Not defined .

Note

You can define the number and the unit of substitutions by means of a rule strategy definition. This definition overwrites the settings that you have made for the number and unit of substitutions in integrated rule maintenance.
