hi,

Get the content of Table into a intenal table. Ex : Use this method GET_STATIC_ATTRIBUTES_TABLE of if_wd_context_node.

Get the index of row seleted which is to be deleted. Ex. Use this mehod GET_LEAD_SELECTION_INDEX of if_wd_context_node.

Delet the row from internal table. <Delete statement>

Bind the internal table again with the node. < Use method bind_table of if_wd_context_node.>

Refer this Sample Code :

data i1 type I.

lo_nd_po->get_static_attributes_table( itab ).

i1 = lo_nd_po->get_lead_selection_index( ).

delete itab index i1.

lo_nd_po->bind_table( itab ).

Hi Raji,

You can use REMOVE_ELMENT of the if_wd_context_node to delete an entry from the UI.

For the underlying DB table you can use the above approaches.

Hi Raji,

to delete the record for the table.

the user will first select the record to be deleted and then clicks the button to delete record.

So on the action of that button you can read the selected record using get_static_atributes.

like...

lo_el_prf_exp_cer_detail->get_static_attributes(

IMPORTING

static_attributes = ls_prf_exp_cer_detail ).

so ls_prf_exp_cer_detail holds the record to be deleted.

so the record can be deleted from DB or temp accordingly to your requirement.
