Function documentationPlanning with Shelf Life Data in PP/DS

 

This process describes how you plan procurement proposals for products in Production Planning and Detailed Scheduling (PP/DS), taking account of shelf life conditions.

Prerequisites

  • You use an SAP ERP system and Production Planning and Detailed Scheduling (PP/DS) from SAP APO.

  • To be able to transfer the shelf life data of products, stocks, and sales orders from SAP ERP to SAP APO, you must have defined CDP as the class system in Customizing for SAP Advanced Planning and Optimization (SAP APO) under Start of the navigation path  Basis Settings Next navigation step Define Class System (CDP or Classical Characteristics) End of the navigation path. You can find the technical details for the transfer in the SAP notes 339576 (valid to SAP R/3 4.5), 394378 (valid as of SAP R/3 4.6), and 483576. For more information, see Integration of Master and Transaction Data.

  • You have maintained the shelf life data for each relevant product in the SAP APO product master and set the Plng w/ shelf life indicator.

  • The Global ATP component does not support planning with shelf life conditions. For that reason, you cannot use this process within a scenario with a Capable-to-Promise (CTP) process or with multilevel ATP (MATP).

Process Flow

The following graphic provides an overview of the process:

  1. You transfer products, stocks, and requirements from the SAP ERP system to the SAP APO system. The SAP APO system uses the transferred shelf life data (stocks and requirements) or the shelf life data from the product master.

  2. You perform planning using various PP/DS applications. First you create procurement proposals using a heuristic for planning standard lots, taking the shelf life conditions into account. You have the following options:

    • If you execute the heuristic using an infinite detailed scheduling strategy, the procurement proposals do not violate any shelf life conditions, but may create resource overloads. You then use the PP/DS optimization, for example, to optimize the resource schedule while taking shelf life conditions into account.

    • If you execute the heuristic using a finite detailed scheduling strategy, the procurement proposals may violate shelf life conditions. To remove the planning problems, plan interactively using push production or the detailed scheduling planning board (DS planning board).

  3. You transfer the procurement proposals to the SAP ERP system

    Note Note

    A pegging relationship created in SAP APO between a requirements element and a receipt element, taking account of the shelf life conditions, is unknown in SAP ERP.

    End of the note.
