--- 提交处理事务处理接口请求

l_request_id := FND_REQUEST.SUBMIT_REQUEST(

APPLICATION => 'INV',

PROGRAM => 'INCTCM'

);

IF ( l_request_id = 0 ) THEN

RAISE E_SUBMIT_FAILED;

RETURN;

ELSE

COMMIT;

L_REQUEST_FLAG := FND_CONCURRENT.WAIT_FOR_REQUEST(

REQUEST_ID => L_REQUEST_ID,

INTERVAL => 5,

MAX_WAIT => 0,

PHASE => L_PHASE,

STATUS => L_STATUS,

DEV_PHASE => L_DEV_PHASE,

DEV_STATUS => L_DEV_STATUS,

MESSAGE => L_MESSAGE

);

END IF;

COMMIT;

EXCEPTION

WHEN E_SUBMIT_FAILED THEN

ERRCODE := '1';

ERRMSG := '提交处理事务处理接口请求失败!'||SUBSTR(SQLERRM,1,100);

FND_FILE.PUT_LINE(FND_FILE.LOG,ERRMSG);

ROLLBACK;

RETURN;

END;

今天关注到这个问题,将找到的资料收集在这里:

1、关于fnd_request.submit_request的用法

fnd_request.submit_request的用法:

FND_REQUEST.SUBMIT_REQUEST 函數是用來提交一個請求的,它返回一個NUMBER值.具體調用如下

:result := fnd_request.submit_request(application CHAR, --AP模快

program CHAR, --應用程式

description CHAR, --請求說明(可選)

start_time CHAR, --RUN 時間(可選)

sub_request BOOLEAN, --立刻提交請求

argument1 CHAR, --參數1

argument2 CHAR, --參數2

argument3 CHAR, --參數3

argument4 CHAR, --參數4

argument5 CHAR, --參數5.......

argument100 CHAR);

英文說明(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

fnd_request.submit_request('AR',

'SVAINEX_P',

'',

'',

FALSE,

:parameter.invoice_store,

chr(0),

'','','',

'','','','','','','','','','','','','','','','','','','','',

'','','','','','','','','','','','','','','','','','','','',

'','','','','','','','','','','','','','','','','','','','',

'','','','','','','','','','','','','','','','','','','','',

'','','','','','','','','','','','','','','');

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,

5,

0,

l_phase,

l_status,

l_dev_phase,

l_dev_status,

l_message);

IF l_request_status THEN

IF l_dev_status = 'NORMAL' THEN

NULL;

ELSE

Fnd_Message.Debug('请求运行不成功:'||l_dev_status);

RETURN;

END IF;

ELSE

Fnd_Message.Debug('请求未完成,无法查看报表内容!');

RETURN;

END IF;

Editor_Pkg.Report(l_request_id,'Y');

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form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。
