ABAP Object Oriented Reporting

ABAP reports are usually written in non-object oriented blocks of code. Project goal is to create a bridge between this non-OO and OO world. So with this bridge you can create an object oriented report. There are still some limitations.

So how to create an OO report:

Create an executable report in ABAP editor
Include ZBC_OO_REPORT_BRIDGE:

INCLUDE zcrm_oo_report_bridge.

Create a selection screen (if needed)

SELECTION-SCREEN BEGIN OF BLOCK b01 WITH FRAME TITLE text-b01.
 PARAMETERS:
   gv_param      AS CHECKBOX.
SELECTION-SCREEN END OF BLOCK b01.

Create your own report class definition (let's say lcl_report), inherit from the class lcl_report_base and implement abstract method "start".

CLASS lcl_report DEFINITION INHERITING FROM lcl_report_base FINAL.
  PUBLIC SECTION.
	 METHODS:
	   start REDEFINITION.
...

Add this single line, this will initialize the "bridge"

set_report_class lcl_report.

Implement your class:

CLASS lcl_report IMPLEMENTATION.
	METHOD start.
	ENDMETHOD.
...

You can copy the provided example class ZBC_OO_REPORT_BRIDGE_EXAMPLE.

To handle selection screen events just redefine the following methods from superclass:

on_load_of_program event is triggered by the ABAP runtime environment when one of the executable programs mentioned above is loaded into the internal session.
on_initialization method for initializing an executable program
on_sel_screen_output triggered by the dynpro event PBO of a selection screen
on_sel_screen_user_command first you have to register user command handling using the method SET_SEL_SCREEN_VALID_FOR_UCOMM in method ON_INITIALIZATION:

set_sel_screen_valid_for_ucomm( 'FC01' ).

on_sel_screen_exit_command called when exit command is called on selection screen
on_sel_screen_validation called before report execution (START-OF-SELECTION)
on_sel_screen_value_request you have to register fields using macros:

register_value_req_for_param <param_name>.
register_value_req_for_selopt <selopt_name>.

to get the current values on selection screen do not read directly the parameter/selopt, but call method get_sel_screen_value
