How To
Click to edit heading

You're creating a new matter and you've enabled automatic matter file numbering, but you're assigned a Non Unique matter number. This occurs when a file number is being assigned that is the same as an existing or deleted matter. Matter numbers must be unique and cannot be reused, even if the associated matter has been deleted.

    If you encounter “You do not have security access to perform this action” message when accessing Application settings page, ask your LEAP Admin to: Navigate to LEAP Menu > Settings > Application Settings > Member > User Profile > Access and Permissions > Client Side Securities – General Then enable “Administrator.”
    This provides access to Application Settings only, does not provide full admin rights.
