Concept Introduction

The Enrollment application is based on the following concepts:

Business Object Layer (BOL)

The business object layer (BOL) model is a programming concept that allows for uniform application development, decoupled from interface changes in the underlying business object-specific application programming interfaces (APIs). The Enrollment application uses the following BOL models, which you can access by using transaction GENIL_MODEL_BROWSER:

Model for ESS Benefits (HRBENF)
Each plan category is represented as a dependent object and related to root object (PERNR_BEN) with cardinality 0…N. Plan categories are related to dependents such as, beneficiaries, investments, and dependents.
HRPAD
For more information, see Business Object Layer (BOL).

Note Note

Each plan category is identified using the assigned key structure and attributes structure. The following table lists the key structures and attribute structures for all the plan categories in the application:

End of the note.

Plan Category/Dependent Object Name in the BOL Model	Key Structure	Attribute Structure
Health Plan / HEALTH_PLANS	HRESS_S_BEN_HEALTH_KEY	RPBEN_OA
Insurance Plan / INSURANCE_PLANS	HRESS_S_BEN_INSURANCE_KEY	RPBEN_OB
Savings Plan / SAVINGS_PLANS	HRESS_S_BEN_OTHERPLANS_KEY	RPBEN_OC
FSA Plan / FSA_PLANS	HRESS_S_BEN_OTHERPLANS_KEY	RPBEN_OD
Miscellaneous Plan / MISCELLANEOUS_PLANS	HRESS_S_BEN_MISCEL_KEY	RPBEN_OE
Stock Plan / STOCK_PURCHASE_PLANS	HRESS_S_BEN_OTHERPLANS_KEY	RPBEN_OF
Credit Plan / CREDIT_PLANS	HRESS_S_BEN_OTHERPLANS_KEY	RPBEN_O1

The dependencies between plan categories and other dependent objects are identified using the assigned key structure and attributes structure. The following table lists the key structures and attribute structures for all the dependent objects of plan categories in the application:

Dependent Object	Key Structure	Attribute Structure
Dependents	HRESS_S_BEN_DEPENDENTS_KEY	HRESS_S_BEN_DEPENDENTS
Beneficiaries	HRESS_S_BEN_BENEFICIARIES_KEY	HRESS_S_BEN_BENEFICIARIES
Investments	HRESS_S_BEN_INVESTMENTS_KEY	HRESS_S_BEN_INVESTMENTS

The following table lists the dependent objects for each plan category:

Plan Category/Dependent Object Name in the BOL Model	Dependents	Beneficiaries	Investments
Health Plan / HEALTH_PLANS	Yes	No	No
Insurance Plan / INSURANCE_PLANS	No	Yes	No
Savings Plan / SAVINGS_PLANS	No	Yes	Yes
FSA Plan / FSA_PLANS	No	No	No
Miscellaneous Plan / MISCELLANEOUS_PLANS	Yes	Yes	Yes
Stock Plan / STOCK_PURCHASE_PLANS	No	Yes	No
Credit Plan / CREDIT_PLANS	No	No	No

Generic Interaction Layer (genIL)
The generic interaction layer (genIL) connects the Model for ESS Benefits (HRBENF) BOL model to the HCM backend, business logic, or database.

The Enrollment application uses the genIL class, GenIL Implementation for GenIL Object Model HRBENF (CL_HRESS_BEN_HRBENF_IL), which implements the BOL model. This class uses the handler class, Handler Class for Dependent Objects of GenIL Model HRBENF (CL_HRESS_BEN_GENIL_HANDLER) to perform all create, read, update, and delete activities on all of the enrollment objects in the database.

You can modify the standard Enrollment application to suit your business needs, by doing the following:
- Familiarize yourself with the Web Dynpro ABAP UI technology. For more information, see Web Dynpro for ABAP.
- Expand your knowledge of the SAP Floorplan Manager. For more information, see Floorplan Manager for Web Dynpro ABAP.
- Expand your knowledge of the main elements in the Enrollment application in Employee Self-Service (ESS) Web Dynpro ABAP. For more information, see Application Composition.
- Execute the necessary configuration steps for the application. For more information, see Configure Enrollment.
