## Paradigm Error Resolution <a href="#paradigm-error-resolution" id="paradigm-error-resolution"></a>

This error is triggered by a Unit Enrolment coded outside the accreditation date of the course record. You need to cross-check these two fields in Paradigm to resolve this error: **Accreditation Date** (**E609**) of the Base Course record (**Courses** > **Edit Details**, *see* [Edit Base Course](https://docs.silverband.com.au/home/paradigm-knowledge-base/curriculum-management/workflows/manage-base-courses/edit-a-base-course-record)), and the **Start Date** (**E534**) of the student’s Unit Enrolment record (**Student** > **Course Enrolment** > **Units**, *see* [Edit Unit Enrolments](https://docs.silverband.com.au/home/paradigm-knowledge-base/student-enrolments/workflows/manage-unit-enrolments/edit-a-unit-enrolment-record)).
