Mosaic may show that a client was transferred to Abacus Admin through the Mosaic Provider Portal, even though the client can't be found or accessed in Abacus Admin. This can happen when an import exception has been raised because the client's National Health Service (NHS) number or National Insurance (NI) number is marked as invalid.
To check this follow these simple steps:
Go to Abacus Admin.
Click Service Users, then click Administration, then click Service User Import Exceptions Work Tray.
Review the list to see any clients with exceptions caused by invalid NHS or NI numbers.
If you update the NHS or NI number in Mosaic, the client should import successfully during the next import, and their exception will be cleared from the Work Tray.
