Hi,
I'd like to use triggers to insert some data on my specific Tables. For example I'd like to isert UserRoles.UserID to my specific table RM.
For this I have tried :

Create TRIGGER Insert_into_RM ON UserRoles
            FOR INSERT
             AS
                 INSERT into RM(idrm)
                 SELECT UserID
                  FROM inseted

the Trigger is created , but when I try to add users to Roles I'm having this following Error : Manage Roles is currently unavailable .
When I drop trigger I can Manage Roles.
Please how can I do?
