Hi experts!

I have some doubts

Where we define USER COMMAND in ALV?

How we find Business objects?

How we find a bapi for particular screen?

Is there any other way of finding an error in Call transaction except checking in BDCMSGCOLL?

Thanks in advance

It depends, if you are using the Function module REUSE_ALV_GRID_DISPLAY, then the user command is implemented in a FORM routine. So when passing the name of the form routine to the function call, you must also have the FORM routine defined.

YOu need to pass the name of a subrotine to the parameter:

I_CALLBACK_USER_COMMAND and you should write the code iin that subroutine:

call function 'REUSE_ALV_GRID_DISPLAY'

exporting

I_CALLBACK_USER_COMMAND = 'USER_COMMAND'

form user_command using ucomm like sy-ucomm

selfield type slis_selfield. "#EC CALLED

Write your code to handle the user commands.

endform.

Hi Jawad,

You should register the event USER COMMAND for the particular grid instance you have created. After this you can create a class which would handle this event, an event handler.

You can go through the sample programs provided by SAP.

Goto SE38 and type BCALV and hit F4. You'll find a variety of programs related to ALV, event-handling etc.

Hope this helps you.

here sending u the sample code....where nd how to use USER COMMAND

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'

EXPORTING

i_callback_program = sy-repid

i_grid_title = l_title

i_callback_user_command = 'USER_COMMAND'

Look for all changed records.

If you have futher query plz reply.....

the use is also similar for

1. REUSE_ALV_GRID_DISPLAY

Thank-You.
