hi friends...
I am practising the WDA programs...
in that they hav used this code
data wd_table type ref to cl_wd_table.
wd_table ?= view->get_element( 'TABLE' ).
wd_this->table_control ?= wd_table->_method_handler.
wd_this->table_control->set_key_attribute_name( 'MATNR' ).
i don't know why they used this code...
here ( ?= ) what is the purpose of this ?= ?
what is the purpose of this class cl_wd_table ?
i am not clear with all statement, can you guide me..
i am waiting for ur reply
regards
