Hi Heera Ramanunny,
when ever you have created table view in that there is a method do_init_context double click on that method and change at last select_single into select_multiedit. then we can edit table filed..
snippet code:
typed_context->contextnode->set_selection_mode(lv_selection_mode = cl_bsp_wd_context_node_tv=>select_ multiedit).
and write the this code in your add button.. it might help full to edit all the fields
types : BEGIN OF TY_LINE,
ex type table-fieldname. " decalre your fileds like this
ex1 type table-fieldname1.
END OF TY_LINE.
data : lr_valuenode type ref to cl_bsp_wd_value_node,
wa_line type ref to ty_line.
CREATE DATA wa_line.
CREATE OBJECT LR_VALUENODE
EXPORTING
IV_DATA_REF = wa_line.
typed_context->contxtnode->collection_wrapper->add( lr_valuenode ).
Thanks & Regards
