AVS error 4737
WarningNAT00120Activity End Date
What it means
Outcome 70 (continuing) used with an activity end date in the past.
How to fix it
If the learner has finished, record the final outcome with the actual final assessment or withdrawal date. If the activity is genuinely continuing, record a defensible expected end date (set the course expected completion period, or set the date on the enrolment).
Does RTObase catch this automatically?
Yes, RTObase validates this against your own data before you lodge and takes you straight to the field to fix it, so this error usually never reaches AVS.
