Prerequisites for Aggregated Planning 

Use

To execute aggregated planning in Supply Network Planning (SNP), you have to fulfill the following prerequisites:

·        You have made the master data settings and any other settings necessary for executing the SNP heuristic or the SNP optimizer. For more information, see Running the Heuristic in the Background and Running the Optimizer in the Background.

You have also defined the master data appropriately for aggregated planning. For more information, see Master Data Setup for Aggregated Planning.

·        For aggregated planning and planning with aggregated resources, there is the standard planning book 9ASNPAGGR with data views SNPAGGR(1) and SNPAGGR(2) based on the standard planning area 9ASNP02. This planning area and planning book contain the key figures required for aggregated planning and the assignment of key figure attributes, such as the Aggregation indicator and the key figure functions 9001 to 9026. The Aggregationindicator specifies whether the aggregated value or the normal value is calculated and displayed at header location product level in a key figure. This indicator also controls whether the value is kept or deleted at sub product level after aggregation.

However, you can also use the standard planning area and planning book as a basis for creating your own planning area and planning book. For more information, see Planning Area Administration and Planning Book.

·        If you use the standard planning area 9ASNP02, standard hierarchy structures are already assigned to it. They form the basis for the hierarchies that you create yourself. However, you can also create your own hierarchy structures for location products, resources, and production process models (PPMs) or production data structures (PDS), and assign them to the planning area you are using (Aggregated Planning tab page). For more information, see Master Data Setup for Aggregated Planning and Hierarchy.

·        Standard planning book 9ASNPAGGR also contains auxiliary key figure NETDM that SNP disaggregation uses as a basis for determining product demand. The system uses macro Net Requirements (Disaggregation)to calculate the net requirements at sub product level that are stored in this key figure and takes into account the stock on hand. It ignores the demand from previous periods (shown in the Supply Shortage key figure) and only considers the demand starting with the period containing the value to be disaggregated.

If you wish to calculate product demand differently for SNP disaggregation, you can also create your own demand key figure for the planning book as an auxiliary key figure and use a macro to define your calculation formula. Assign key figure function 9010 (Aggr. Planning: Disaggregation Demand) to this key figure. For more information, see Planning Book Maintenance and Advanced Macro Structures.

·        You have specified Delete at sub location product levelin the Aggr.: Old Orders field in Customizing for SNP under Basic Settings → Maintain Global SNP Settings (this is only valid for the example process described in Aggregated Planning. See step 4).

If you want to use order groups, you must also have specified Use order group in the Agg: Order Group field. The system considers the order group during aggregation and disaggregation. You can also use the order group after disaggregating data from header to sub product level to determine the connectivity between the orders at header and sub product level, as well as between the individual orders at sub product level, for example.

·        You have released the forecast data from demand planning (DP) or from an OLTP system to the level of the sub products in SNP. The planning data must be available at sub product level for aggregated planning. For more information, see Release of Forecast Data.
