Form Access Failure: Incorrect Custom Top Environment

Yes, this can happen if the environment context for the custom top holding the Blitz Report form is not set up correctly, or if the application tier was not restarted after running `autoconfig`. You should verify that the `$XXEN_TOP` environment variable is set correctly by navigating to Help > Diagnostics > Examine and checking Block: `$ENVIRONMENT$`, Field: `XXEN_TOP`.

If the environment check passes, the issue might be a corrupt definition of the `XXEN_REPORTS` function itself. You can verify its definition by querying `fnd_form_functions_vl` to ensure it is defined as a FORM type under the ‘Enginatics Custom Application’ (XXEN_REPORTS).
