Function documentationDIF Occurrences on Product Substitution

 

Following a switchover to the replacement product, the system creates DIF occurrences according to the settings in the substitution merge profile.

Integration

  • The system uses DIF occurrences in order to explain notable fluctuations in the consumption data of a location product. For more information, see Demand Influencing Factors.

  • After starting the program to create and enrich switchover information, the system automatically creates DIF occurrences according to the substitution merge profile.

    Example Example

    The system automatically creates DIF occurrences for the source location:

    You set, for example, in the substitution merge profile a DIF ID for the original and the replacement product in the source location (the DC) and also merging for the store. You assign this profile to a substitution assignment with location type store. Once the product substitution has been run, the system merges the transaction data for the store. In addition, the system creates DIF occurrences of type Ignore Historical Values for the combination of original product and DC and also the combination of replacement product and DC. Therefore, SAP F&R ignores the irregular goods issues of the DC in the forecast calculation for the DC. If the DC delivers to 1000 stores, and a substitution assignment exists for each store with the same substitution merge profile, then, for each store, SAP F&R creates DIF occurrences for the DC in case of product substitution. This can be up to 1000 DIF occurrences for the combination of original product and DC and also up to 1000 DIF occurrences for the combination of replacement product and DC.

    End of the example.

  • The system also takes into account DIF occurrences that have been created manually in the DIF Workbench.

Note Note

  • If SAP F&R merges transaction data for a DC following a product substitution at this DC, ensure if possible, that the system does not create a DIF occurrence for the DC following a product substitution at a store.

  • If a DIF occurrence of type Ignore Historical Values exists, SAP F&R ignores irregular goods issues of the DC in the forecast calculation for the DC. Note that SAP F&R forms a mean value in the DIF period from the consumption values taken before and after the period. In cases where it is not possible to derive a mean value, SAP F&R uses the forecast procedure for newly listed products.

End of the note.

Prerequisites

  • You have fulfilled the prerequisites for product substitution in the forecast and requirements calculation.

  • You have created DIF IDs of type Ignore Historical Values , which you wish to use in the substitution merge profile. For more information, see the Implementation Guide (IMG) of Forecasting and Replenishment under Start of the navigation path Demand Influencing Factors Next navigation step DIF Occurrences End of the navigation path.

  • You can only create DIF occurrences that use DIF type Ignore Historical Values.

Features

  • By specifying DIF IDs in the substitution merge profile, you can determine which DIF occurrences (with reference to source and target location) you wish to create.

  • To create the DIF occurrences, you can run the program for Creating and Enriching Switchover Information.
