英文说明(zt oracle) :
Parameters are as follows:

application - Short name of the application associated with the concurrent
request to be submitted.

program - Short name of the concurrent program (not the executable) for which
the request should be submitted.

description - Description of the request that is displayed in the Concurrent
Requests form (Optional.)

start_time - Time at which the request should start running,formatted as HH24:
MI or HH24:MI:SS (Optional.)

sub_request - Set to TRUE if the request is submitted from another request and
should be treated as a sub-request.

argument1...100 - Arguments for the concurrent request; up to 100
arguments are permitted. If submitted from Oracle Forms,you must specify all
100 arguments.

补充说明：
在用fnd_request.submit_request的时候，第五个参数用false，不要被参数名称误导；这个函数有105个参数，前面五个定义请求本身，后面100个是传递给请求的具体参数，都是Char类型，我们需要转换，默认值是chr(0)，代表这个参数不用传递给调用的请求；
在Package里面调用只需要传递需要的参数个数，因为它有默认值指示结束；
在form里面则不行，要写满105个，而且我们参数结束之后要用一个chr(0)来表示结束

例
fnd_request.submit_request('AR',
'SVAINEX_P',
'',
FALSE,
:parameter.invoice_store,
chr(0),'','');

例如：

1--submittherequest
2l_req_id_fee:=fnd_request.submit_request('PO',
3REQIMPORT4''56FALSE,245)">7POP_REQUEST8to_char(SYSDATE,YYYYMMDD),245)">9ALL1011N12);

2、Oracle Erp等待报表运行机制

主要是用到了Fnd_concurrent.wait_for_ruqest这个function.
Fnd_concurrent.wait_for_request返回Boolean值，主要参数如下：
function FND_CONCURRENT.WAIT_FOR_REQUEST
(request_id IN number default NULL,--请求ID
interval IN number default 60,--检查时间间隔
max_wait IN number default 0,--最大等待时间
phase OUT varchar2,
status OUT varchar2,
dev_phase OUT varchar2,--请求运行阶段
dev_status OUT varchar2,--各个阶段状态
message OUT varchar2 --运行完成后输出信息)
return boolean;

dev_phase有Pending,Running,Complete,Inactive等几种，每种对应不同的Dev-Status，比如Complete阶段后就有Normal,Error,Warning,Cancelled,Terminated等几种状态。

例如：

l_request_status:Fnd_Concurrent.Wait_For_Request(l_request_id,245)">25l_phase,245)">l_status,245)">l_dev_phase,245)">l_dev_status,245)">l_message);
IFl_request_statusTHENl_dev_statusNORMALNULLELSEFnd_Message.Debug(请求运行不成功：'||l_dev_status);
RETURNEND18请求未完成,无法查看报表内容!20Editor_Pkg.Report(l_request_id,245)">Y23

总结：FND_REQUEST.SUBMIT_REQUEST是一种通过后台方式提交请教的方法，可以在pkg和form中使用，在中使用要将参数写全。FND_CONCURRENT.WAIT_FOR_REQUEST是一个等待当前请求运行完毕的程序，可以利用这个等待当前的请求程序运行完毕再运行下面的程序。

3、有时候提交请求一直会返回0的情况：检查是否有初始化环境：

3.1、在PLsql中设定初始的方法

SELECT user_id
INTO l_num_user_id
FROM applsys.fnd_user
WHERE user_name ='user_name';

SELECT responsibility_id
INTO l_num_resp_id
FROM apps.fnd_responsibility_vl
WHERE responsibility_name ='responsibility_name';

SELECT application_id
INTO l_num_resp_appl_id
FROM applsys.fnd_application
WHERE application_short_name = 'app_short_name';



fnd_global.apps_initialize (user_id => l_num_user_id,
resp_id => l_num_resp_id,
resp_appl_id => l_num_resp_appl_id);

3.2、在Form设定初始的方法

-- 可直接引用全局变量
fnd_global.apps_initialize (user_id =>FND_GLOBAL.APPS_INITIALIZE(FND_GLOBAL.USER_ID,

resp_id =>FND_GLOBAL.RESP_ID,242)"> resp_appl_id =>FND_GLOBAL.RESP_APPL_ID);
