Structure of vendor data
Oracle vendor data consists of a vendor header at the system level and one or more vendor sites are at the operating unit level, which is the equivalent of the Maximo® Manage site level.

Maximo Manage vendor data consists of a vendor master at the set level and one or more vendor records at the organization level. An organization has only one vendor set, but a vendor set can belong to more than one organization.

The integration framework passes the Oracle E-Business Suite vendor site records to Maximo Manage organization level. The integration framework determines Maximo Manage set identifier from the organization information about the inbound vendor record.
Before you use the integration framework, you must configure the relationship between company master sets and Maximo Manage organizations in the Sets application.
The company identifier in Maximo Manage is a concatenation of the Oracle E-Business Suite operating unit, vendor ID (SEGMENT1), and vendor site code.

The integration framework does not create the company masters. To direct Maximo Manage to create a company master for each inbound vendor it creates, select the Automatically Add Companies to Company Master checkbox in the Sets application. If you do not, errors occur.
Although Maximo Manage allows a one‐to‐many relationship between company masters and company record, a one‐to‐one relationship for vendors exists that is added by using the vendor integration.
