Purpose

To describe how to use Dynamic Safety Stock in PP/DS.

Overview

Dynamic safety stock is read from interactive Supply Nework Planning (SNP), and it also can be taken into account in Production Planning and Detailed Scheduling (PP/DS). This page explains how to consider dynamic safety stock in PP/DS. It includes corresponding customizing and an example. 

 This page will describe the steps that need to be taken in order to make PP/DS consider the Dynamic Safety Stock maintained in SNP application.

Table of Content

Relevant customizing

  • /SAPAPO/MVM - take Safety Stock into Account.
  • /SAPAPO/RRPCUST1 - set SNP planning area
  • Make SNP Key Figures Available in customizing
  • /SAPAPO/MAT1 - set safety stock method

Example Creation

  • SNP Planning Book: 9ASNP_SSP
  • Dataview: SAFETY
  • Planning Area: 9ASNP05
  • Safety Stock Key Figure: 9ASAFETY - SafetyStock(Planned)
  • Location: PL0001@Q63002
  • Product:  MTS-FERT@Q63002

Step 1: Check the customizing

In this example, in transaction /SAPAPO/MVM, set "2" - Consider Virtual Safety Stock Elements

In transaction /SAPAPO/MAT1, set safety stock method, e.g. MB

In transaction /SAPAPO/RRPCUST1, set planning area 9ASNP05

In the following customizing, make SNP key figures available

Input planning area 9ASNP05, planning object 9AMALO, and Key figure 9ASAFETY and 9ASVTTY (9ASVTTY is used in other safety stock method e.g. MZ)

Step 2: Maintain safety stock in SNP planning book

In transaction /SAPAPO/SDP94, open planning book 9ASNP_SSP dataview SAFETY, load location product,  input safety stock  value e.g. 100, 130, 120, 100

Check Safety Stock in Product View

The virtual requirements can be calculated

  • 0 -100 = -100
  • 100 - 130 = -30
  • 130 - 120 = 10
  • 120 - 100 = 20
  • 100 - 0 = 100

Check the safety stock in APO product view

    1. Hi Guest.

      PP Planning Procedure has no relation to Dynamic Safety Stock.
      Planning Procedure will determine what actions the system will take for a given event (e.g. whether the Product Heuristic has to start immediately when a new dependent demand is created for a given component).
