QA check API not working fine

I am using below API for QA check. However it is always returning Success, eventhough QA check has error if done from front end.

okc_qa_check_pub.execute_qa_check_list
(p_api_version => ln_api_version
,p_init_msg_list => OKC_API.G_TRUE
,x_return_status => lv_return_status
,x_msg_count => LN_MESSAGE_COUNT
,X_MSG_DATA => LV_MESSAGE_DATA
,p_qcl_id => 11001
,p_chr_id => 41062
,P_OVERRIDE_FLAG => 'N'
,x_msg_tbl => lT_msg_tbl
);

Any Advice on this...

is anything wrong with this, or something wrong at my end or i should use any other API.
