How to refresh OOP ALV table after first display

[Former Member]

Hi Gurus,

I have created a OOP ALV using custom control. I have a pushbutton in my screen also.

When I click the push button (Refresh Delivery Dues) for the first timeu2026u2026u2026it will refresh the ALV values with new values, but if u click 2nd / 3rd u2026time, it will not refresh ALV,

But in Debug mode, I see that values are updated and the internal tables are also modified with new valuesu2026.but it will not displayed in ALV. I also call set_table_first_display after refresh but it also not working.

i use below code when clicking the Push Button.

In PAI

Case sy-ucomm.

WHEN 'REF_ORDERS1'.

PERFORM get_sales_orders.

LOOP AT gt_zbs001_sod INTO gs_zbs001_sad.

PERFORM icon_led USING gs_zbs001_sod-werks

CHANGING gs_zbs001_sod-icon

gs_zbs001_sod-count.

gs_zbs001_sod-date = time_bdelv.

MODIFY gt_zbs001_sod FROM gs_zbs001_sod INDEX sy-tabix TRANSPORTING date.

ENDLOOP.

LOOP AT gt_zbs001_sad INTO gs_zbs001_sad.

PERFORM icon_led USING gs_zbs001_sad-werks

CHANGING gs_zbs001_sad-icon

gs_zbs001_sad-date = time_bdelv.

MODIFY gt_zbs001_sad FROM gs_zbs001_sad INDEX sy-tabix TRANSPORTING date. "p_es_row_no-row_id.

ENDLOOP.

Hello,

The method u2018refresh_table_displayu2019 is enough to call the ALV grid with the updata data But please call the same in the PBO.

For instance, if the container is initial, then call the method u2013 u2018set_table_first_displayu2019 else call the method u2018refresh_table_displayu2019.

If you want to limit the number of calls on u2018refresh_table_displayu2019, then put a logic like when the related internal table changes, call this method.

My point is, just confirm that you are calling the method u2018refresh_table_displayu2019 in the PBO.

Hello,

I understood that the ALV is getting refreshed when you click the push button. But my doubt is this u201Cwhy do you click many times after refreshu201D. I can see another scenario here. If you are modifying many rows of the ALV and trying to refresh, it may be not be working even though it is working in debug mode. Here it may work for a single row without any issue. So my suggestion is to use u201CWAITu201D.

WAIT UP TO 5 SECONDS. (No of seconds you can change according to you program)
