Hi Raja,
I am not closing Page B, it's closing automatically when I select the value in table View the following code will trigger in OninputProcessing event to collect the selected value and pass back to Page A through navigation variable 'nv_Value'.
    tv_table ?= cl_htmlb_manager=>get_data( request = request
                                         name    = 'tableView'
                                         id      = 'tv_tabid' ).
    IF tv_table IS NOT INITIAL.
      tv_data = tv_table->data.
      navigation->set_parameter( name = 'nv_Value' value = tv_data->SELECTEDROWKEY ).
      navigation->goto_page( 'A.bsp' ).
    ENDIF.
Problem is with Page 'A', the values which I enetered in other fields are refreshing when I goback to page 'A' from Page 'B'.
Please help.
Thanks,
Giri
