That is Dynamic subroutine.

Every form or routine has perform. There is no perform without its definition in form.

Just double click on perform and it will take you to the form. If it does not, then there is not form for it. Try to activate and you should get error

Thanks,

Normally these forms are initiated or used in ALV standard func. module reuse_alv_grid_display or list_display, so you won't find any perform statements for these function modules. Look into above function modules.

See the following example....

user_command will be a separate form in ALV report.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

I_INTERFACE_CHECK = ' '
I_BYPASSING_BUFFER = ' '
I_BUFFER_ACTIVE = ' '

Yes, You can have it.

For example you can call a form using dynamic calls as follows:

lv_form_name = 'TEST'.

perform (lv_form_name) in program ztest.

In program ztest write this:

form test.

write:/ 'test'.

endform.

Take the folowing example .

REPORT demo_mod_tech_perform_dyn .

DATA: progname(24) TYPE c VALUE 'DEMO_MOD_TECH_FORMPOOL_1',

subrname(8) TYPE c.

subrname = 'SUB1'.

PERFORM (subrname) IN PROGRAM (progname) IF FOUND.

subrname = 'SUB2'.

PERFORM (subrname) IN PROGRAM (progname) IF FOUND.

I hope this will help you.
