See Authorisation code has expired or is not working for assistance with this error.
If you’re an Indirect associate, Responsible authority or Government representative, you may have received this error when either renewing or editing an authorisation.
When renewing or editing your authorisation, you need to ensure that the end date of the current authorisation doesn’t overlap with the start date of any other authorisations for the same user for the business.
To resolve this, check your existing authorisation in RAM and then change the end date of your renewal or edited authorisation so they do not overlap.
