Hi,

Refer the Wd component WDR_TEST_INPUT_OUTPUT. View CURR's WDDOINIT method this method has been called.

• declare callback for single node

l_node_info = l_root_info->get_child_node( 'SINGLE_PRICE' ).

l_node_info->set_attribute_ref_callback(

name = 'PRICE'

callback_object = me

callback_method = 'GET_REFERENCE_ELEMENT'

reference_field_type = if_wd_context_node_info=>reffieldtype_curr

).

Hope this helps.

Best regards,

Suresh
