ALV through OOPS

former_member193947 — Wed, 26 Aug 2015 18:42:20 GMT

Hi Guru's,

I have an working ALV report that calls REUSE_ALV_GRID_DISPLAY to display the internal table content.

Since our standard's don't accept FORM / ENDFORM usage after it became obsolete, I need to change the complete report to OOPS based approach.

I need to replace the below forms especially into oops approach.

FORM pf_status USING p_extab TYPE slis_t_extab.

ENDFORM.

FORM user_command USING r_ucomm LIKE sy-ucomm rs_selfield TYPE slis_selfield.

ENDFORM.

Can someone please post example code on how to achieve this?

Thanks.

Check SLIS package in SAP.

Particulary, check programs BCALV_GRID_*

Hello Sap Seeker,

You might try using the Class cl_salv instead of the function module. This class is extremely easy to use.

And you can treat the user commnds with event handling. Your report will be entirely OO.

I just copied this fro ma code I wrote some days ago.

FORM f_print_alv .

"Build the output table in alv

TRY.

cl_salv_table=>factory( IMPORTING r_salv_table = o_table

CHANGING t_table = t_wtm019 ).

CATCH cx_salv_msg.

MESSAGE e846 WITH text-e02. "Error

ENDTRY.

* Define the column attributes

o_columns = o_table->get_columns( ).

TRY.

o_column ?= o_columns->get_column( 'MANDT' ).

o_column->set_visible( space ).

o_column ?= o_columns->get_column( 'VBELN' ).

o_column->set_cell_type( if_salv_c_cell_type=>hotspot ).

CATCH cx_salv_not_found.

MESSAGE e846 WITH text-e02. "Error

ENDTRY.

"Set all ALV functions

o_functions = o_table->get_functions( ).

o_functions->set_all( abap_true ).

"Set ALV Zebra

o_display = o_table->get_display_settings( ).

o_display->set_striped_pattern( cl_salv_display_settings=>true ).

"Set Events

o_events = o_table->get_event( ).

CREATE OBJECT o_event.

SET HANDLER o_event->on_single_click FOR o_events.

"Print ALV

o_table->display( ).

ENDFORM. " F_PRINT_ALV

For handling the events such as single_click, this is the code:

*---------------------------------------------------------------------*

* CLASS lcl_handle_events DEFINITION

*---------------------------------------------------------------------*

CLASS lcl_handle_events DEFINITION.

PUBLIC SECTION.

METHODS:

on_single_click FOR EVENT link_click OF cl_salv_events_table

IMPORTING row column.

ENDCLASS. "lcl_handle_events DEFINITION

*---------------------------------------------------------------------*

* CLASS lcl_handle_events IMPLEMENTATION

*---------------------------------------------------------------------*

CLASS lcl_handle_events IMPLEMENTATION.

METHOD on_single_click.

PERFORM f_call_va03 USING row column.

ENDMETHOD. "on_single_click

ENDCLASS. "lcl_handle_events IMPLEMENTATION

If you want to handle the user command, you change to this:

*---------------------------------------------------------------------*

* CLASS lcl_handle_events DEFINITION

*---------------------------------------------------------------------*

* Define uma classe local para handle events

*---------------------------------------------------------------------*

CLASS lcl_handle_events DEFINITION FINAL.

PUBLIC SECTION.

METHODS:

on_user_command FOR EVENT added_function OF cl_salv_events

IMPORTING e_salv_function.

ENDCLASS. "lcl_handle_events DEFINITION

*---------------------------------------------------------------------*

* CLASS lcl_handle_events IMPLEMENTATION

*---------------------------------------------------------------------*

* Implementação da Classe Local de Handle Events

*---------------------------------------------------------------------*

CLASS lcl_handle_events IMPLEMENTATION.

METHOD on_user_command.

CASE e_salv_function.

WHEN 'XD01'.

"Create Customer

PERFORM f_create_customer.

WHEN OTHERS.

ENDCASE.

ENDMETHOD. "on_user_command

ENDCLASS. "lcl_handle_events IMPLEMENTATION

Hope this helped,
