Supersession Settings in SPP

To be able to use the full scope of Supersession in Service Parts Planning (SPP) , you must make the following settings.

Customizing of Master Data for Product and Location Interchangeability

You define the IMG Activity Maintain Attribute Properties for Supersession Chains. in Customizing for Advanced Planning and Optimization by choosing Start of the navigation path Master Data Next navigation step Product and Location Interchangeability Application Settings End of the navigation path .If you want to use supersessions in Service Parts Planning, you can copy the settings delivered in the standard system.You only have to make changes for the following fields that are described in the table:

Description	Relevance	Required	Display	Location Dependency	Active
Planning Date Successor Product	Planning and ATP	No	Yes	Location Specific	Yes
Demand Percentage for Demand Quantity	Planning and ATP	No	No	Cross Location	Yes
Data Realignment End Date	Planning and ATP	No	Yes	Location Specific	Yes
Successor Product Receipt Date	Planning and ATP	No	Yes	Location Specific	Yes
Demand Percentage for Demand Quantity	Planning	No	No	Cross Location	Yes
Stock Exhaustion Date	Planning and ATP	No	Yes	Location Specific	Yes
Stock Exhaustion Warning Date	Planning and ATP	No	Yes	Location Specific	Yes
Data Realignment End Date	Planning	No	Yes	Location Specific	Yes
Use-Up Date	Planning and ATP	No	No	Both	Yes
Use-Up Strategy	Planning and ATP	No	No	Both	Yes
Valid-From Date	Planning and ATP	Yes	No	Both	Yes
Planning Date Successor Product	Planning	No	Yes	Location Specific	Yes

To be able to model all replacement strategies supported by SPP, you assign the following replacement types in Customizing for Advanced Planning and Optimization by choosing Start of the navigation path Master Data Next navigation step Product and Location Interchangeability Application Settings Maintain Interchangeability Group Types and Assign Supersession Types End of the navigation path under the interchangeability type Supersession Chain .

Replacement Type	Description
S_1P0P	1:0 Substitution
S_1P1P	Product-Product
S_1P1PPT	1:1 Substitution (Partial)
S_1P1PRE	1:1 Substitution of Remanufactured Product
S_1PNP	1:Many Substitution (AND)
S_1PNPOR	1:Many Substitution (OR)
S_NP1P	Many:1 Substitution (AND)
S_NP1POR	Many:1 Substitution (OR)

To be able to use replacement strategies in Service Parts Planning, deactivate the following standard validations in Customizing for Advanced Planning and Optimization under Master Data Product and Location Interchangeability Consistency Checks Maintain Validation :
- S_V3
- S_V8
- S_V18
- S_V20
To be able to use the replacement strategies in Service Parts Planning , set the PPDS DeActivate indicator in Customizing for Advanced Planning and Optimization under Master Data Product and Location Interchangeability Application Settings General Settings .

Service Parts Planning Customizing

You carry out the IMG activity Assign Replacement Types to Replacement Strategies in Customizing for Advanced Planning and Optimization under Supply Chain Planning Service Parts Planning (SPP) Supersession .For more information, see the Implementation Guide (IMG).
You define buffers and time periods in the IMG activity Make Settings for Calculating Supersession Times in Customizing for Advanced Planning and Optimization under Supply Chain Planning Service Parts Planning (SPP) Supersession .
You define the maximum horizon for determining the stock exhaustion warning date and, optionally, a DRP profile in Customizing for Advanced Planning and Optimization under Supply Chain Planning Service Parts Planning (SPP) Supersession in the IMG activity Define Service Profile for Supersession .If the system cannot calculate a stock exhaustion date within this horizon, it does not set a planning date for the successor product.

Planning Service Manager

You schedule the planning service “SPP: Supersession Service” (SPP_SUPERSESSION) in the Planning Service manager (PSM). For more information, see Use of the Planning Service Manager for Service Parts Planning .

Master Data

You create supersession chains on the SAP Easy Access screen by choosing Start of the navigation path Advanced Planning and Optimization Next navigation step Master Data Application-Specific Master Data Product and Location Interchangeability End of the navigation path .Note that the replacement chain is assigned to the active model.For more information, see Master Data for Product and Location Interchangeability .
