ALV issue - capturing user changes in editable fields using custom button?

Former Member — Thu, 05 Feb 2009 18:11:09 GMT

Hi,

I created a custom button in ALV tool bar. And also in my ALV grid I have couple of fields Editable option. User can change values for these 2 fields.

My question is -

After changing values for these editable fields(more than 1 record) , user will click on custom button and then I have to update all the user changed values in to my internal table(lt_tab) and then I have to process logic.

Problem is when user click on Custom button in ALV tool bar it is not having the changed values in lt_tab table.

Only when user clicks some thing on ALV grid records or fields then it is getting all the changed values in to lt_tab.

Can any one tell me how I can get changed values when user clicks on custom button?

1. Can we place custom button in ALV Grid? instead of ALV tool bar?

How I can capture user changes when they click on custom button?

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

TABLES

T_OUTTAB = lt_tab

Please check this logic-

CASE r_ucomm.

WHEN '&IC1'.

- It_tab having all changed field values

WHEN 'custom button'.

lt_tab - not having any changed values - showing all initial lt_tab values.

I highly appreciate your answers on this.

Thanks.

Rajesh.

You would need to refresh the ALV list first using the refresh_table_display method, for instance.

Please check that you are not overriding any standard funcionallity. BTW are you using class or functinos? Also did you debug? That is the most easiest to understand.

This will reflect all the changes in the internal table. Now you can include your logic as per your requirement.

Hope this solves your problem.

Hi all,

Thanks for the answers, I found the logic from documentation and its working fine.

Thank Tarun , I put almost same logic, its working now.

But I am having one more issue hear.

Using ALV tool bar Filter option if we do any filter ALV records and after user command I am still seeing the complete records, not the filtered records.

It is not refreshing my internal table with new filtered records.

I need to get filtered records (what ever is showing in current ALV grid after user does his changes like modifying records or filtering with his own conditions?

Any suggestions. Thanks for your time.

Thanks.
