For the Sort-Dump i got finlay a solution.

The Reason for the sort-dump is, because when you Sort your ALV-Table the lead selection get lost.

and if you implement, for example an imput fead with a binding of your alv table-field you get a dump.

but i got a solution for this.

1. Go in you view or component controller (where you implementet you alv table binding)

in the proportys area and be shoure to embed the interfacecontroller of your alv table.

2. create a method (i called it ALV_AFTER_FUNCTION) with the Event ON_STD_FUNCTION_AFTE

From the Interfacecontroller.

3. put in this Coding

DATA  l_context_node TYPE REF TO if_wd_context_node.
   l_context_node = wd_context->get_child_node( name = wd_this->wdctx_zberufuverf ).
   l_context_node->set_lead_selection_index( index = 1 ).

zberufuverf is my context node

no wenn you so sort you table the method above starts and set the lead selection ...:D

Hi Kiran,

You have to use the below code in the WDDOINIT method,

CALL METHOD lv_value->if_salv_wd_std_functions~set_sort_complex_allowed
   EXPORTING
     value  = ABAP_TRUE.

After executing the application you will get the filter and settings options in ALV toolbar.

Click on settings->Go to Sort tab->Select your column name which you want to sort->Click on Add->Apply->Ok.

Hi V A,

Thanks for your reply.

Actually i am getting the sort and filter options and those working fine.But my issue is once if you apply sort and filter option for columns,this also works fine,later if you selects one of the row from alv table and click the details button,it will opens in the other view perfetcly ,here if you do any events like enter or radio butto check....throws the dump.

If you do not apply any sort on ALV table and did same like select row and click details,it goes another view and perform any events ...working fine.....

Regards,

Kiran
