Multi-Org features in Oracle EBS 11i and R12

Generally, Oracle 11i fulfills multi-org feature by the views in apps schema; while Oracle R12 fulfills the feature by Virtual Private Database feature.

In 11i,  the base table are created by product schema, e.g. oe_order_headers_all in ont db schema. In apps schema, there’s a view called oe_order_headers, which has a where clause like “org_id = SUBSTRB (USERENV (‘CLIENT_INFO’), 1, 10)” . So every user accessed application has his own userenv, then every user can access his own org’s data.

In R12, the base table are also created by product schema, e.g. oe_order_haders_all in ont schema. In apps schema, there’s a Synonym oe_order_headers with VPD feature to fulfill the multi-org feature.

In 11i, we set MO: Operating Unit profile on the responsibility level, then all of user logged from this responsibility has this OU(org_id) client info, so this user can only access this operating unit data from this responsibility.

In R12, we set up a security profile, which can include several operating units, then we assign this security profile to the profile option “MO: Security Profile” on the responsibility level.  The user logged from this responsibility can access all of OUs’ data  in the security profile.
