Unable to update Ztable data through program

Former Member — Tue, 02 Aug 2016 06:23:29 GMT

Hello Guys,

I am creating a new ALV Report which need to display some dropdown columns in it. I have done this through OOPS concept without using function modules REUSE_ALV_GRID_DISPLAY_LVC or REUSE_ALV_GRID_DISPLAY or REUSE_ALV_LIST_DISPLAY. The report is working fine but when I select values from dropdown columns and try to refresh the internal table data through GET_GLOBALS_FROM_SLVC_FULLSCR but is coming Initial.

Please help me as I have to finish this ASAP.

Thank You in Advance.

Hi,

If you are using ALV OOPs then why are you using this function module to refresh internal table data.?

In class CL_GUI_ALV_GRID , there is a standard method to check and get the changed data .

Call this method - CHECK_CHANGED_DATA.

Regards

Ashish

Thanks for instant reply, but how to use that method when object is null. I tried and it gives dump error " Access via 'NULL' object reference not possible.".

You have created an object for clas cl_gui_alv_grid, call it by that .

Where are you calling it.? Is there any button which you are pressing for refreshing the internal table.?

IF ref_grid IS INITIAL.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IF NOT ref_grid IS INITIAL.

CALL METHOD ref_grid->check_changed_data.

ENDIF.

MODIFY zqals FROM TABLE it_qals. "insert if no record found else update

IF sy-subrc = 0.

Tell me one thing, why are you declaring a new data type ref_grid TYPE REF TO cl_gui_alv_grid.

And you are not even creating any object. What is the main object you created for displaying the table , in you PBO module.?

Call this method by that object. It will work.
