Configuring the Back-End 

Use

You have to create a structure in the ABAP Dictionary, in parallel to the one for the application you created in the front-end.

Procedure

...

       1.      Create a package with the following properties:

○     Package: PAOC_FACE_ESS_SERVICES

○     Package interface: PAOC_FACE_ESS_SER_RFW_IF

○     Error severity: None

       2.      Create and implement your own ABAP class.

The class contains the business logic of the application. It has to implement the interface IF_HRXSS_SER_RFW. The interface contains the following components:

○     C_ACTION_INIT

○     C_ACTION_EXIT

○     C_WD_TRUE

○     C_WD_FALSE

○     C_FORM_TYPE_PDF

○     C_FORM_TYPE_HTML

The interface also contains the method process_action. This method is called for each action (such as INIT or EXIT) that is triggered by the GRT or the front-end application.

       3.      Create the communication structure in the ABAP Dictionary.

In doing so, you define the structure for communication with the front-end. The structure must correspond entirely to the structure in the front-end that you created in Configuring the Front-End. The object names must be written with the same capitalization, otherwise data cannot be exchanged between the front-end and the back-end.

The GRT also includes the standard structure HRXSS_SER_RFW_IF_VCNAV0. This structure is linked with the VcRfwNav0 structure of the visual application component (Vc).

       4.      Assign the front-end application to the ABAP class. The back-end table T7XSS_SER_RFW is used for the assignment between the application ID and the class that implements the interface.

                            a.      Call up the maintenance view of the T7XSS_SER_RFW table.

                            b.      Create a new entry for your application. Enter the application ID and the name of the ABAP class.
