ALV GRID REFRESH ISSUE!!!

Former Member — Wed, 24 Nov 2004 12:55:24 GMT

Hello all,

I added a refresh button on my ALV display List.

It should bring the latest sales data.

This is how it was handled.

List Header for Top-Of-Page

PERFORM comment_build.

Fill the Field Catlog details

PERFORM fieldcat_init USING 'IT_ALV_HBOM'.

Modify the Field Catalog

PERFORM modify_fieldcat.

Fill the necessary events

PERFORM eventtab_build USING gt_events.

Sort Fields

PERFORM sort.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_buffer_active = 'X'

i_callback_program = g_repid

i_callback_pf_status_set = gc_status

i_callback_user_command = gt_user_command

is_layout = gs_layout

it_fieldcat = v_fieldcat[]

i_save = g_save

is_variant = gs_variant

it_events = gt_events[]

it_sort = it_sort

IMPORTING
e_exit_caused_by_caller = g_exit_caused_by_caller
es_exit_caused_by_user = gs_exit_caused_by_user

TABLES

t_outtab = p_table

EXCEPTIONS

program_error = 1

OTHERS = 2.

FORM user_command USING r_ucomm LIKE sy-ucomm

rs_selfield TYPE slis_selfield .

case sy-ucomm.

when refresh.

select latest data from database.

and all call the ALv display again.

es_exit_caused_by_user = gs_exit_caused_by_user

TABLES

t_outtab = p_table

EXCEPTIONS

program_error = 1

OTHERS = 2.

endcase.

endform.

PROBLEM I AM FACING IS ..

I get a display of ALV, but when i say BACK or CANCEL it goes to the previous list of ALV.

How do i over come this issue?

Hi Manohar,

You should not call FM 'REUSE_ALV_GRID_DISPLAY' for the second time. In the callback routine USER_COMMAND you should just set the field REFRESH of structure rs_selfield.

John.

There is no need to call reuse again within your callback routine.

Just change the field refresh of structure Structure RS_SELFIELD as described in the online help.

Christian

RS_SELFIELD contains the following information:

tabname : Name of the internal output table

tabindex : Index of the internal output table

fieldname: Field name

endsum : Cursor is located on the totals line

sumindex : If >0, the cursor is located on a subtotals line

value : Value of the field on the list

refresh : (Exporting) List should be set up again
