This code was created by another developer and I need to achieve higher coverage to deploy an unrelated project. My test class (psuControllerTest) is receiving a test failure. It looks like it does not like the last part of the code where the "Status" is set. Any help with correcting the test code is much appreciated.

Method Name:

psuControllerTest.testPsuIdRequest

Message:

System.DmlException: Update failed. First exception on row 0 with id a0HP0000001ivPOMAY; first error: INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY, insufficient access rights on cross-reference id: []

Stack Trace:

Class.psuIdRequestController.setStatus: line 88, column 13 Class.psuIdRequestController.Approve: line 45, column 9 Class.psuControllerTest.testPsuIdRequest: line 176, column 9 External entry point
