Refresh data in ALV OM

[Former Member]

I am using CL_SALV_TABLE to generate ALV report with a refresh button.

When I click on Refresh button, the data should be updated

In the on_user_command event I have

perform select_data
my_alv->refresh( ).

But this does not seem to accomplish the task. What am I missing? Thank you.

But I am already doing that. I am extracting the data again before calling refresh().

Try to call display again

perform select_data
my_alv->refresh( ).
my_alv->display( ). " <<--

Actually just calling my_alv->display() does not do it. But if I perform display_list which contains all the display components, the report does get updated.

But why do I have to call display() again. When I look at demo program SALV_DEMO_TABLE_REFRESH, they do not call display() again. So even though this solution works, I am trying to understand why I have to implement display() again.

Previously i have this issue while working with docking container, if i add a node in the left pan corresponding data will not refresh automatically in the right pan with ONLY using ->crefresh. Then i tried with ->refresh & ->display it works.

But i don't know the reason.

I was able to get it working. Thanks for that. I am not sure either why display() needs to be invoked again but as long as it works.

I have a bigger issue though and I have posted a separate ques for it, here it is. Would you be able to assist me on this one?

I am trying to print an ALV report that has far too many columns and so they get chopped off and dont print. Have you faced a similar issue?
