The purpose of this WIKI is to explain  the Master data in the SNP-APO.


This wiki will make an overview of the Master data settings in SNP-APO, showing the tabs and explaining important fields to configure.


The planners can access the capacity leveling by the following transactions:

  • Change mode: /sapapo/mat1 
  • Display mode: /sapapo/rrp3


Master data is the core data that is essential to operations in a specific business or business unit.

Master data is the essential data (about products, locations, resources, production process models (PPMs), and so on) that is necessary to build a supply chain model and execute planning. 

Using the Master data, the planners can transform the model business information in to tangible data to the system process.


This tab is responsible for the horizons of the business.

•SNP Production Horizon: SNP does not create any planned orders in the Production (planned) key figure, but moves production to the first day after this horizon.


•SNP Stock Tranfer Horizon: Enter the number of days, weeks, or months during which the system is not to plan stock transfers The system does not generate any planned distribution receipts within this horizon; instead, it moves them to the first day after the SNP stock transfer horizon.

Obs: The horizon starts on the system date or date defined in the Planning Start Date field of the planning book.

Lot Size

In this tab the planners can adjust the minimum lot size and de maximum lot size according to the process constraints.


  • Minimum Lot Size: This value specifies the minimum quantity for each order.


  • ŸŸMaximum Lot Size: This value specifies the maximum quantity for each order.


ŸAnother important point in this tab  is the Period Factor. This factor used by the system to calculate the availability date/time of a receipt element within a time period (bucket).

 You can enter a factor between 0 and 1, where 0 is the start of the period, 0.5 the middle, and 1 the end of the period.

 To use this fator you must to set the flag “Use period factor”



In the procurement tab tha planner can choose the Procurement Type, that's it, defines how the product is procured.
The following procurement types are available:
  • F - external procurement: run the plan to a external location
  • E - in-house planning: run the plan into the locarion

  • X - external or in-house production: run the plan both in a in-house location and external location


Obs:If you do not enter anything in the field, the system assumes X.


Here, the planner can adjust the good receipt and good issue processing times according to the  process constraints.


  • ŸGood Issue Processing Time: The time between issuing the product from storage and transporting it.


  • ŸGood Receipt Processing Time: The time between the delivery or the production of a product and its availability as stock.
