Process documentationProduct Substitution in the Forecast and Requirements Calculation

 

You can use this process in order to take account of the switchover information that has been either imported for product substitution or generated in SAP F&R as part of the forecast and requirements calculation in SAP F&R.

Using the master data assignments and switchover information transferred from SAP ECC to SAP F&R, SAP F&R automatically plans the follow-up product or the original product in the case of a replacement product.

Note Note

You can use this process both in connection with SAP ECC and also exclusively with SAP F&R and your own systems from which you import the required data.

Prerequisites

  • You have activated the consideration of substitute products at client level in SAP F&R. For more information, see the SAP Implementation Guide (IMG) under Start of the navigation path Forecasting and Replenishment Next navigation step Master Data Next navigation step Define Settings at Client Level End of the navigation path.

  • You have defined a substitution merge profile in SAP F&R Customizing. For more information, see the IMG under Forecasting and Replenishment under Start of the navigation path  Substitution Products Next navigation step Substitution Merge Profiles End of the navigation path.

  • You have imported the following data to SAP F&R:

  • If you have defined the use of a Business Add-In in the substitution merge profile, you must implement this BAdI (/FRE/FU_FRP_BADI008). For more information, see the SAP Implementation Guide (IMG) under Start of the navigation path Forecasting and Replenishment Next navigation step Substitution Products Next navigation step Enhancements Using Business Add-Ins Next navigation step BAdI: FRP – Merge Stock and Consumption End of the navigation path.

Process

  1. You generate switchover information and enrich the switchover information. For more information, see Creation and Enrichment of Switchover Information.

  2. If there is a switchover to the follow-up product, then SAP F&R controls planning of original and follow-up products using lock behavior in the location product.

  3. According to the settings defined in the substitution merge profile, the system merges (before the start of the forecast and requirements calculation) the stocks, consumptions and order proposals of the original product with those of the substitution product.

    For more information, see Merging of Transaction Data.

  4. The forecast and requirements calculation generates order proposals whereby the system takes the product substitution (including the merged transaction data and the generated DIF occurrences) into account:

    • In a switchover to the follow-up product, the system plans the follow-up product and generates order proposals with the follow-up product.

    • In a switchover to the replacement product, the system plans the original product (if planning of the original product is scheduled in SAP F&R) and generates order proposals with the original product.

      If SAP F&R is already planning the replacement product, it also generates order proposals with the replacement product.

    Note Note

    Following a product substitution with switchover to the replacement product, SAP F&R continues to plan the same products as prior to a switchover. If the system, for example, was not planning the replacement product before a product substitution, then the situation does not change after the product substitution.
