error 3624 when inserting data from Navision

mthe80

Using Navision with sql database. Win 2003

Have one of mibusoer have experience with this kind of error?
This error comes from sql server.

One of my friend has faced it ones but now he faced it again. The first time he faced, he use sql server with SP3a and meet this error when posting data from general journal.
Now, when he created a new sales order line, he get that kind of error.
(already tried to restart the server) :?:
