Employment Record Numbers

Employment record numbers (ERNs), in combination with a person's ID, uniquely identify a person's job data records. The system distinguishes between a person's organizational instances by using a new ERN when you create a new instance.

The system also creates a new ERN when you create a job data record in the following circumstances:

Action	Comments
Create concurrent jobs, including: Additional assignments. Additional organizational instances. (JPN) Additional appointment (kenmu). (CHE) Multicontract.	Use the Add Additional Assignment component (ADD_PER_ORG_ASGN) to add an additional job (using the action of Add Additional Job) to the one an employee or contingent worker already holds. This job is added to an existing organizational instance, retains the employment dates of the original job, and is terminated if you terminate the original job. Note: Access the Concurrent Job Data component (JOB_DATA_CONCUR) from the Add Additional Assignment component. Use the Add Employment Instance component or Add Contingent Worker Instance component to create an additional organizational instance for a worker using the action Hire. This job record is not tied to any other jobs that the worker holds, has its own job data, and has its own hire dates. HIR is used in the Add Employment Instance only. The Add Contingent Worker Instance component uses the ADD action. Note: Additional organizational instances are identified as hires on human resources reports and additional assignments are not. Use this distinction to guide how you enter additional jobs in the system. If you do not need to distinguish between concurrent jobs, choose one method of entering concurrent jobs and use it consistently. See (Classic) Adding Organizational Instances. See Adding Additional Assignments. See Understanding Additional Appointments.
Create a global assignment (employees only).	Use the Home/Host Information component (HOME_HOST_DATA) to create a global assignment job record. The system gives the global assignment (host) job record a new employment record number to distinguish it from the employee's original (home) job record. See PeopleSoft Human Resources Track Global Assignments: Understanding Global Assignment Tracking.
Create a temporary assignment, including Japanese intercompany transfer (shukkou).	When you assign a worker to a temporary assignment on the Job Data component, the system suspends the substantive job and identifies the temporary job record with a new employment record number. See Entering Temporary Assignments. See Understanding Intercompany Transfer Tracking.

Example: A Person with Multiple ERNs

Jan Smith is hired to work in the sales division of Sutter Enterprises. After two years of outstanding performance, she starts a six-month temporary assignment in a subsidiary company to assist with the launch of a new application. At the end of the assignment she returns to her original job, but three months later she takes on a consulting role at the subsidiary in addition to her sales job. This table lists the changes to Jan's job records over the three-year period:

Action Date	Employment Instance	Contingent Worker Instance
May 1, 2016	Employment instance created. Job record identified by: ID: 8901 ERN: 0 Organizational relationship: employee
May 1, 2018	Substantive job suspended.
May 1, 2018	New job record for temporary assignment created. Job record identified by: ID: 8901 ERN: 1 Organizational relationship: employee
November 1, 2018	Temporary assignment completed.
November 1, 2018	Substantive job resumed.
February 1, 2019	No change to employment job record.	Contingent worker instance created. Job record identified by: ID: 8901 ERN: 2 Organizational relationship: contingent worker

This diagram illustrates Jan Smith's job records under the organizational relationships. Under the person record, there are separate employee and contingent worker organizational instances. There are two ERNs under the employment instance and one ERN under the contingent worker instance. Each ERN has its own event history:
