You need to get the current content of the node and assign to an internal table.

Then append the new row to this internal table and bind the new internal table.

In your submit button action you need to code to bind your new internal table with new row added

Hi Thandlam,

Read Context node of the ALV data internal table, add one empty record to that internal table then again bind same internal table to the same context node.

I hope this will works.

Can you post the code of how to insert a row to an ALV table upon the button click event ?

These are the steps:

1. Get the data in the node in Component Controller bound to DATA node of ALV in internal table.

     lo_node = wd_context->get_child_node( 'NODE' ).

     lo_node->get_static_attributes_table( IMPORTING table = lt_data ).

2. Now insert an empty row to this internal table.

     CLEAR: wa_data.

     APPEND wa_data TO lt_data.

3. Bind this table again to the node.

     lo_node->bind_table( lt_data ).

Oh... I thoug there was an event handler in ALV which does that job.

There is an another way.

You may want to read this article. It gives Standard button to insert a new row.

The point of focus should be IF_SALV_WD_STD_FUNCTIONS~SET_EDIT_INSERT_ROW_ALLOWED( ).

Hi,

Actually above mentioned alternate way is not applicable for my issue , because when i press submit button( for data base table update) then only new row need to add but above alternate way applicable only when we press the append or insert button ... these are standard alv button.
