Application Composition of Personal Profile Services 
This section informs you about the main elements which a Personal Profile service in Employee Self-Service (and based on Web Dynpro ABAP) consists of.

Figure 1: Component Encapsulation with GUIBBs
Figure 1 shows the encapsulation of several Web Dynpro components within one Web Dynpro Application Personal Profile service. The OVP component configuration that the Personal Profile application configuration uses is HRESS_CC_PER_OVP. It consists of the following configurations:
The initial screen contains the WD component HRESS_C_PERNR_SELECTION and its interface view PERNR_SELECTION_MAIN.
The main screen summarizes the employee’s information in the form of business cards (biz cards). The GUIBB for the biz cards is implemented using the feeder class CL_HRESS_PER_OVERVIEW.
Each of the main screens has a corresponding edit page. Edit pages are implemented using the feeder class CL_HRESS_PER_DETAIL.
