Cannot view messages after upgrade from SP07 to SP10

Hi,

we are facing now problem with ITSM - after upgrade, because of our oversight, roles for ITSM was overwriten by new versions, and when user logs into ITSM, it cannot write and even see any tickets.

Only one error message is showing - No authorisation object B_NOTIF_IB

What should we do in this situation?

After giving SAP_ALL profile, user can open ticket by entering its number, but list with this numbers is still gone.
