转:Oracle R12 多组织访问的控制 - MOAC(Multi-Org Access Control)

什么是MOAC

MOAC(Multi-Org Access Control)为多组织访问控制，是Oracle EBS R12的重要新功能，它可以实现在一个Responsibility下对多个Operation Unit(OU)进行操作。MOAC允许用户在不切换responsibility的情况下，在一个responsibility下处理多个OU组织的事务。

User --> Responsibilities --> Single Operation Unit Mode  /  Multiple Operation Unit Mode

一个应用场景:

某集团公司下边主要分为三个区域（北美，欧洲，亚太），亚太区你是一采购部经理，负责所有七个Operation Unit。 这种情况下，系统管理员可以创建一个security profile，这个security profile设置成可以访问这七个亚太组织，并把这个security profile赋予到你的responsibility下，这样你就能在同一个职责下访问这七个OU了，就不用不停地切换职责来访问不同OU了。

另外如果你要经常处理中国OU下的事务，那么你可以设置Profile:MO: Default Operating Unit到中国，那么业务默认的OU就是中国了。

MOAC相关的Profile

有三个主要的Profile

MO: Security Profile :provides access to multiple operating units from a single responsibility.If the MO: Security Profile is set, then the MO: Operating Unit profile will be ignored.

MO: Default Operating Unit :If you set the MO: Security Profile profile option, you can also set an operating unit as the default operating unit using the MO: Default Operating Unit profile option. This is useful when you transact in multiple operating unit but frequently transact in one operating unit.

MO:  Operating Unit :MO: Operating Unit profile option only provides access to one operating unit.

MOAC profiles rules

1) If the profile  option “MO: Security Profile” is not set, then “MO:  Operating Unit”  value is used  as the default Operating Unit even if “MO:  Default Operating Unit” profile is set to a different value.

2) If the profile option “MO: Security Profile” is set and gives access to only one Operating Unit, the default Operating Unit will return this  value even if “MO: Default Operating Unit” is set to a different  value.

3) If the profile option “MO: Security  Profile” is set and gives access to  multiple Operating Units :

-  If the profile value “MO: Default Operating Unit”  is set,  it  is validated  against the list of Operating Units in “MO: Security Profile”.

+ If  the Operating Unit is included in the security profile then it is  returned as the default value.

+ Else there is no defaulted Operating Unit .

-  If the Profile Option “MO: Default Operating Unit”  is not  set,  then there is zero (no)  default Operating Unit.

单组织的案例

单组织即一个Responsibility只访问一个OU，设置情况大体如下，对于职责：Manufacturing and Distribution Manager，

MO: Operating Unit=Vision Operations

MO: Security Profile=空

这样我们在使用职责：Manufacturing and Distribution Manager的时候，就只能访问到Vision Operations的数据，比如创建的PO，这个PO只能处于OU:Vision Operations下，另外所选取的供货商也只能是Vision Operations下的。

多组织的案例

首先定义一个Security Profile，路径：HRMS Super User Responsibility > Security > Define Security Profile，Business Group:Vision Corporation,'Security Type'选择'Secure organizations by organization hierarchy and/or organization list'，并且我们把在Organization Name列表中添加三个OU:Vision Operations，Vision Corporation ，Vision Services.

保存定义的Security Profile,然后在HR职责下，运行“Security List Maintenance” program，“Generate lists for”= One Named Security Profile ，Security Profile是刚刚定义的'PTIAN_SECURITY_PROFILE'。

Security List Maintenance的作用是让你定义的Security Profile生效，能够设置到Profile "MO: Security Profile"（The Security List Maintenance concurrent program must be run each time you add or change Security Profiles.）

System Admin职责下，Profile > System，设置MO: Security Profile为刚刚定义的'PTIAN_SECURITY_PROFILE'

再切回Manufacturing and Distribution Manager职责，打开PO，这个时候，你就可以不切换职责的情况，定义三个OU下的采购订单了。

MOAC的实现原理-VPD技术

MOAC的实现是通过Oracle数据库的VPD(Virtual Private Database)技术来实现的。VPD技术提供了数据库对象（表，同义词，视图）行级别访问的控制。使用VPD技术可以有效地限制用户获取数据的范围。

Secooler 的一篇文章 使用Oracle VPD（Virtual Private Database）限制用户获取数据的范围  讲VPD，里边的例子非常容易理解.

1. --1.Create Data
2. create table t (x number);
3. insert into t values (1);
4. insert into t values (2);
5. insert into t values (10001);
6. insert into t values (10002);
7. commit;
8. select * from t;
9. output:
10. 1
11. 2
12. 10001
13. 10002
14. --2.Create VPD FUNCTION
15. CREATE OR REPLACE FUNCTION f_limited_query_t (s_schema IN VARCHAR2,
16. s_object IN VARCHAR2)
17. RETURN VARCHAR2
18. AS
19. BEGIN
20. RETURN 'X <= 10000';
21. END;
22. --3.Register VPD Policy.
23. BEGIN
24. DBMS_RLS.add_policy (object_schema   => 'APPS',
25. object_name     => 'T',
26. policy_name     => 'POLICY_LIMITED_QUERY_T',
27. function_schema => 'APPS',
28. policy_function => 'F_LIMITED_QUERY_T');
29. END;
30. select * from t;
31. output:
32. 1
33. 2

对于上边例子，我们对表T使用了VPD技术，引入了表限制Function f_limited_query_t，这样我们通过function限制了对表的查询，查询结果只返回小于10000的数字。

如何查看我们是否对某张表使用了VPD技术

SELECT * FROM DBA_POLICIES WHERE object_name = 'T';

查询结果中，其中Pakcage + Function就是我们对于表所加的限制。

那么Oracle EBS是如何使用VPD技术来实现多组织的

R12里,以PO表为例，PO_HEADERS_ALL是基础表(PO/APPS Scehma)，PO_HEADERS是PO_HEADERS_ALL对应的Synonym对象(Apps Schema),我们对PO_HEADERS应用VPD技术.MO_GLOBAL-Dive into R12 Multi Org Design 有较为详细的说明，

In pre Release 12, you would have had following methodology for PO_HEADERS_ALL

a. A table is created in PO Schema, named PO_HEADERS_ALL

b. A synonym named PO_HEADERS_ALL is created in APPS schema, referring to PO.PO_HEADERS_ALL

c. Create a view PO_HEADERS in APPS schema, as "select * from po_headers_all where org_id=client_info"

But now in R12, following will happen

a. A table is created in PO Schema, named PO_HEADERS_ALL

b. A synonym named PO_HEADERS_ALL is created in APPS schema, referring to PO.PO_HEADERS_ALL

c. Another synonym named PO_HEADERS is created in APPS, referring to PO_HEADERS_ALL

d. A Row Level security is applied to PO_HEADERS, using package function MO_GLOBAL.ORG_SECURITY.This can be double-checked by running SQL select * from all_policies where object_name='PO_HEADERS'e. The effect of this policy is that,whenever you access PO_HEADERS, Oracle RLS will dynamically append WHERE CLAUSE similar to below

SELECT * FROM PO_HEADERS WHERE EXISTS (SELECT 1 FROM mo_glob_org_access_tmp oa WHERE oa.organization_id = org_id)

看下下边Query的输出

SELECT * FROM DBA_POLICIES WHERE object_name = 'PO_HEADERS';

可以看到，我们对表PO_HEADERS加了MO_GLOBAL.ORG_SECURITY限制，MO_GLOBAL.ORG_SECURITY的作用实际上就是根据你关于MOAC Profiles的设置，然后转换为相应Where条件(组织过滤)，再进行查询。

对于VPD表的查询

对于VPD表，简单的查询一般是不返回记录的，如果想查到记录，需要设置一下上下文先

--普通查询VPD表

select * from PO_HEADERS;--No Output

--Single OU Mode

BEGIN

execute mo_global.set_policy_context('S',204); --204为ORG_ID,S表示Single Org Context

END;

select * from PO_HEADERS;--会输出OU：204下边的所有PO

--Multiple OU Mode(simulate login to a specific responsibility)

a. Call fnd_global.apps_initialize(userid,resp_id,resp_appl_id);

b. call MO_GLOBAL.INIT(p_appl_short_name);

This will read the MO profile option values for your responsibility/user, and will initialize the Multi Org Access.

c.select * from po_headers

MOAC API

What is the purpose of MO_GLOBAL.ORG_SECURITY?

The purpose of Row-Level-Security is to hide certain data[based on some conditions]. RLS does so by appending a where clause to the secured object.1. MO_GLOBAL.ORG_SECURITY is a function that returns a predicate for the WHERE CLAUSE2. The where clause will be appended to Table/Synonym/View for which Multi Org Row Level security is enabled

What is the purpose of MO_GLOBAL.SET_POLICY_CONTEXT ?

This procedure has two parameters    p_access_mode          Pass a value "S" in case you want your current session to work against Single ORG_ID          Pass a value of "M" in case you want your current session to work against multiple ORG_ID's    p_org_id          Only applicable if p_access_mode is passed value of "S"

支持MOAC功能的Form开发步骤

这部分摘自:http://bbs.erp100.com/thread-103395-1-1.html

在R12版本中，OU的控制采取了MOAC的方式，使用户的操作得到了改善。 而如果客户化的Form能够支持MOAC的功能，需要在界面上提供当前用户可以选择的OU字段供用户选择。
功能展示如下图：

这样在Form的开发过程中需要如下的开发步骤：

1,PRE-FORM 触发器初始化MOAC配置环境

添加如下代码：

MO_GLOBAL.init(‘ONT’);

— global.mo_ou_count

— global.mo_default_org_id

— global.mo_default_ou_name

IF l_default_org_id IS NOT NULL THEN — default org id not null

MO_GLOBAL.SET_POLICY_CONTEXT(‘S’,l_default_org_id);

ELSE

MO_GLOBAL.SET_POLICY_CONTEXT(‘M’,null);

END IF;

— default org id not null

这段代码的作用是根据预制文件的设置，初始化OU的信息，将用户可以访问的OU信息插入到mo_glob_org_access_tmp表中，

同时将默认的OU ID、OU Name和OU Count分别写到global.mo_default_org_id, global.mo_default_org_id, global.mo_default_ou_name   具体细节可以查看数据库包：mo_global
2,WHEN-CREATE-RECORD触发器中拷贝OU默认值

在此触发器中将默认的OU ID和OU Name拷贝给Form界面上对应的字段，实现创建记录的时候默认带出默认OU信息。

copy(name_in(‘global.mo_default_org_id’),’’);   copy(name_in(‘global.mo_default_ou_name’),’’);
3,创建OU的LOV

Form界面上的OU 名称字段创建一个LOV，LOV对应记录组的SQL语句如下：

SELECT hr.organization_id organization_id, hr.NAME organization_name

FROM hr_operating_units hr

WHERE mo_global.check_access(hr.organization_id) = ‘Y’

ORDER BY organization_name
其它没有特殊的步骤。
