and Tax Reporting Units: How They Work Together.
This document states
"A payroll statutory unit can pay and report on multiple legal employers. If you have a legal entity that acts as a payroll statutory unit
you can associate it with other legal employers that are not PSUs. This enables you to pay all employees of all legal employers in a single payroll run and perform all the statutory reporting for them." This confirms that the relationship between LEs and PSUs is the critical factor.

This guide explains
"When you hire an employee
you create an assignment for a legal employer. The legal employer is associated with a PSU. The application creates a payroll relationship for the person for that PSU." This establishes the direct link between the legal employer
the PSU
and the creation of the payroll relationship. A change in LE that results in a change of PSU necessitates a change in the payroll relationship.

"Oracle Fusion HCM: Employment Model (Doc ID 2767131.1)"
Section: Payroll Relationship.
This support document clarifies
"A payroll relationship is created when a person is hired into a Payroll Statutory Unit (PSU). All assignments for that person within legal employers that map to that same PSU are grouped under that single payroll relationship." This directly supports the principle that the PSU governs the payroll relationship's existence.
