TCSI Error Description
Please check the list of acceptable codes and report the correct Student Status Code (E490) for the unit enrolment.
Error Logic
If the Student Status Code (E490) is not blank (null), then the Student Status Code (E490) must match a current value in the
RefStudentLiabilityAndStatusType
table on the Unit of Study Census Date (E489).
Paradigm Error Resolution
Check that the value for HEIMS Student Status (E490) on the unit enrolment is an acceptable option as defined by https://www.tcsisupport.gov.au/element/490. Select a valid field value before attempting to submit the unit enrolment again.
