ALV grid control, Adding the push Button in the Toolbar

[Former Member]

Hello All,

I am facing a problem when trying to do calculation based on the button added at the toolbar of interactive ALV list.

When I click on the toolbar button Compute, the ALV should calculate the

multiplication of the Qty (manually entered by a user) & price per unit already available in the ALV & show it the Column Total value.

Presently when I try to do this using

Method handle_user_command.

modifying the inetrnal table GT_FINAL_OUTPUT

with the Total price value .

& updating the column Total price (Qty * price) in the Internal table

After doing this I am agin calling the below function

CALL METHOD g_grid->set_table_for_first_display

EXPORTING

i_structure_name = 'GT_FINAL_OUTPUT'

is_layout = gs_layout

CHANGING

it_fieldcatalog = gt_fieldcat

it_outtab = GT_FINAL_OUTPUT[].

At above function it gives short dump or sometimes it does not update the ALV screen with the new updated value of Total price .

The short dump comes states the error of unassigned field symbol.

Kindly suggest a program where we can do manipulation at the editable ALV.

Or solution to above issue .

You might want to take a look at the ALV code examples here:

Hi,

Please check the fieldcatalog fields should exist in the output table, other wise system will give short dump of field symbol not been assigned.

You should only be calling the SET_TABLE_FOR_FIRST_DISPLAY one time in the PBO of your screen, otherwise you should be using the REFRESH_TABLE_DISPLAY method. IN your PBO, check that the instance of the alv_container is alive, if so, do not call the SET method, rather call the REFRESH method.

if alv_container is initial.

    create object......
    create object g_grid.....
    call method g_grid->set_table_for_first_display......

else.

 call method   g_grid->refresh_table_display( ).

endif.

Hello Colleagues ,

Thanks for your help .

I was using the wrong definition of the fieldcatlog .

when I change the fieldcatlog building with correct mention of table name & fieldname then it solves the problem of shortdump .
