Hi Murali,
Add billow code in CRM_KNOWART_S/KASearchView --> EH_ONSEARCH( ),
before calling get_query_result( ). "(Copy original method Add this line in 110 line)
CALL METHOD lr_query_service->add_selection_param
EXPORTING
iv_attr_name = ''STATUS_TXT'
iv_sign = 'I'
iv_option = 'NE'
iv_low = 'ZXXXXXX'. "=========>Code for Canceled status
I guess this will solve your problem.
Regards
Vijay
