Hi,

If msg is thrown , Selected row in alv disappers , so i can say Lead selection of a node is set to zero .

So my question is how to set the lead selection?

Before throwing the error i used the stmt:

<node>->set_lead_selection_index( index = < value> .

But stil it is not working.

Regards,

Rani.

Hi,

You can store the lead select index of the row in view attribute or some global variable and in WDDOMODIFYVIEW you can set the lead selection index again.

CALL METHOD LO_NODE->SET_LEAD_SELECTION_INDEX
        EXPORTING
          INDEX = wd_this->index.

Here I've stored the lead selection index of row as view attribute 'Index'.

Hope this helps.

Hi,

Up on the error, are you deleting the record.

As you said that that row (lead selection) is getting dissappeared.

Are you binding the table (deleting any records) up on error.

And regarding hte lead selection setting, I think after setting the lead selection you are binding the table again. That could be the problem. After biding the table then set the lead selection index.
