数据库与EBS版本:
RDBMS : 11.1.0.7.0
Oracle Applications : 12.1.2
当在一个concurrent里用fnd_request.submit_request提交一个子请求时,有个叫sub_request的参数,通常我们都设为FALSE,这样子请求可以提起来,
不通过在request的form界面上Parent栏位不会显示父请求的request id。
如果我们直接将sub_request设为TRUE, 子请求就会卡住,报Inactive No Manager。
这时我们可以通过一个叫fnd_conc_global的包来解决:
提交请求前设置退出条件:
l_req_data := fnd_conc_global.request_data;
IF (l_req_data IS NOT NULL)
THEN
l_req_data_i := TO_NUMBER (l_req_data);
l_req_data_i := l_req_data_i + 1;
IF (l_req_data_i > l_tbl_get_language.COUNT)
THEN
EXIT loop_languages;
END IF;
ELSE
l_req_data_i := 1;
END IF;
提交子请求:
l_sub_request_id :=
fnd_request.submit_request (application => 'XXONT',
program => 'XXONT0701',
sub_request => TRUE,
argument1 => p_order_type_id,
argument2 => p_order_num_low,
argument3 => p_order_num_high
);
提交完子请求后,暂停父请求:
fnd_conc_global.set_req_globals
(conc_status => 'PAUSED',
request_data => TO_CHAR
(l_req_data_i)
);
这样提起的子请求是并行运行的。
