Identification Numbers for each Entity in the Master Index (Repository)

Each object profile in a master index application is assigned a unique identification number in addition to the local IDs assigned by individual systems. Each object has one unique identification number throughout your organization, and a unique identification number within each system with which they are registered.

EUID

Every object profile in the master index system is assigned an enterprise-wide unique identification number. This number is the same for that object regardless of the system from which the object information originates. This number is called the enterprise-wide unique identifier (EUID) and is used to cross-reference object profiles in order to accurately identify the objects throughout your organization.

Local ID

A local ID is a unique local identification number that is assigned to an object in each system at which it is registered. These numbers are assigned using a numbering system unique to each local system, and are used internally by the systems to identify each object. A master index application uses an object’s EUID to cross-reference its local IDs in different systems. Note that the name of the Local ID field is configurable and might be different for your implementation.
