As of SAP IBP 2408, if you create a new planning area based on the SAP7F sample planning area, you should use the Application Mappings app to assign master data types and attributes to their respective OBP business meanings and map key figures and sales order catalog fields (SFC fields). Most of our customers can still configure the mappings for their planning areas in the Business Meanings for Order-Based Planning and the Settings for Order-Based Planning app in 2408. Still, they will also be migrated to the new app with the upgrade to the following release.
Since the Application Mappings app is functionally suitable for replacing the Business Meanings for Order-Based Planning app, the latter will be deprecated over time. However, the Settings for Order-Based Planning app will continue showing the active key figure and SFC field mappings in the planning area: these will remain available in display mode to help you set the period types for your key figures and apply additional settings.
Purpose and Features of Application Mapping
The Application Mappings app offers a mapping functionality that ensures correspondence between the OBP application and your planning area entities. It enables you to customize and apply sample mappings or build mappings from scratch, depending on your business requirements.
Using the Mapping Delivered with SAP7F Planning Area
To use a planning area, you must have an active mapping between application mappings and planning area entities. 
Mapping Validity
The validity of a mapping indicates whether the included model entities and application mappings assignments comply with application-specific requirements.
A mapping becomes invalid in the following cases:
- The configuration of modeling entities is modified, but the changes do not comply with OBP requirements.
- The planning area is activated with dependencies and limited scope.
For more information, please refer to SAP Help documentation.
Activation of Application Mapping
If you have completed your application mapping assignments, you must activate your mapping so that OBP can use it. 
Key Figure Mapping
If using the 2408 SAP7F planning area, the Key Figure Mapping by Planning Area version is not in Settings for Order-Based Planning.
Most of the fields in Settings for Order-Based Planning would be read-only using the 2408 SAP7F Planning Area.
