A.首先最重要的是要在pre-form中初始化多OU
BEGIN
APP_STANDARD.EVENT(‘PRE-FORM’);
//必须在APP_STANDARD.EVENT()后执行
MO_GLOBAL.init ('INV');--参数可以使’S’—单OU，’M’-多OU，或者已经注册过的应用简称
END;
B.初始化后获取OU的信息，在Pre-form中获取OU信息，或在块上When-Create-Record获取OU信息
Pre-form
DECLARE
l_default_org_id number;
l_default_ou_name varchar2(240);
l_ou_count number;
BEGIN
...
mo_utils.get_default_ou(l_default_org_id, l_default_ou_name, l_ou_count);
:PARAMETER.mo_default_org_id) := l_default_org_id;
:PARAMETER.mo_default_ou_name := l_default_ou_name;
:PARAMETER.mo_ou_count := l_ou_count;
...
END;
When-Create-Record
IF :parameter.mo_default_org_id is not null and :block.org_id is null THEN
:block.org_id := :parameter.mo_default_org_id);
:block.operating_unit := :parameter.mo_default_ou_name;
END IF;
C.在各个触发器实现多OU的支持的代码
When-Create-Record Trigger of Operating Unit Field Block
IF (:parameter.mo_default_org_id IS NOT NULL ) THEN
-- Defaulting org_id from profile option
:block.org_id := :parameter.mo_default_org_id;
:block.operating_unit := :parameter.mo_default_ou_name;
-- Set policy context
mo_global.set_policy_context('S’,:block.org_id);
ELSE
mo_global.set_policy_context('M', null);
END IF;
IF :<your block name.org_id> is not null\
IF :<block name.org_id> <> nvl(:<parameter.old_org_id>,-99) THEN
-- Get the cache for current org
END IF;
ELSE
-- Refresh the cache
...
END IF;
When-Validate-Item Trigger of Operating Unit field
IF (:<your block name.org_id> IS NOT NULL ) THEN
IF :<block name.org_id> <> nvl(:<parameter.old_org_id>,-99) THEN
mo_global.set_policy_context('S', :block.org_id);
-- Get the cache for the current org
END IF;
ELSE -- :block.org_id is null
mo_global.set_policy_context('M', null);
-- Refresh the cache
END IF;
When-New-Record-Instance Trigger of Operating Unit Field Block
IF (:<your block name.org_id> IS NOT NULL ) THEN
IF :<block name.org_id> <> nvl(:<parameter.old_org_id>,-99) THEN
mo_global.set_policy_context('S', :block.org_id);
-- Get the cache for the current org
END IF;
ELSE -- :block.org_id is null, so set the context to multiple
mo_global.set_policy_context('M', null);
-- Refresh the cache
END IF;
Pre-Insert Trigger of Operating Unit Field Block
Use this trigger if the form allows the user to commit multiple records.
IF (:<your block name.org_id> IS NOT NULL ) THEN
IF :<block name.org_id> <> nvl(:<parameter.old_org_id>,-99) THEN
mo_global.set_policy_context('S', :block.org_id);
-- Get the cache for the current org
END IF;
ELSE -- :block.org_id is null, so set the context to multiple
mo_global.set_policy_context('M', null);
-- Refresh the cache
END IF;
Pre-Query Trigger of Operating Unit Field Block
BEGIN
IF :parameter.mo_ou_count = 1 THEN
mo_global.set_policy_context(‘S’,:parameter.mo_default_org_id);
ELSE
mo_global.set_policy_context('M', null);
END IF;
-- Other Code
END;
Pre-Record Trigger of Operating Unit Field Block
use this trigger if the form forces the user to commit each record.
IF (:parameter.current_record is not null and
:parameter.current_record != :system.trigger_record) THEN
IF (:system.form_status in ('CHANGED','INSERT')) THEN
mo_global.set_policy_context('S', :parameter.old_org_id);
-- Get the cache for the current org
-- raise error message to the user to commit;
-- raise form_trigger_failure;
ELSE
-- No pending commits.
-- Reset the current record variable.
:parameter.current_record := '';
END IF;
ELSE
-- User has not navigated to another record.
-- Do not reset the current record variable.
null;
END IF;
Pre-Update Trigger
Use this trigger if the form allows the user to commit multiple records commits that are in different operating units.
IF (:<your block name.org_id> IS NOT NULL ) THEN
IF :<block name.org_id> <> nvl(:<parameter.old_org_id>,-99) THEN
mo_global.set_policy_context('S', :block.org_id);
-- Get the cache for the current org
END IF;
END IF;
