Hi Prabha,

While implementing the method handle_toolbar for the first screen say u can add ur own custom buttons and for the screen screen implement another method say handle_toolbar_2.

See the below code for reference.

**Handle Toolbar

METHOD handle_toolbar.
DATA: ls_toolbar TYPE stb_button.
CLEAR ls_toolbar.

**add user button to the ALV toolbar

MOVE 'SAVE' TO ls_toolbar-function.
MOVE '@2L@' TO ls_toolbar-icon.
CLEAR ls_toolbar-disabled.
APPEND ls_toolbar TO e_object->mt_toolbar.

ENDMETHOD . "handle_toolbar

METHOD handle_user_command.
PERFORM validation USING gv_mgpln.
ENDMETHOD.

*reward if this helps.

Rgds,

Sandeep

HI Prabha

if you want to offer multiple functions on a single ALV row then these functions should not be assigned to specific columns of the ALV list because the user would need to memorize which column "allows" which function. Furthermore, this would not be according to SAP style guidelines.

The solution to your problem are context menus. The following sample report shows you how to add two functions to the context menu of the ALV list and how to execute these functions.

In addition, if you double-click on a row (= customer) the sales area details will be displayed in the second ALV list.
