Error while trying to save new employee

  We are trying to save an employee, and the following is the error we get, we have found a few hits on metalink but no fix is given as such.

These hits suggest to log in and log out , and also some details about the automatic number generation code

but we need to know why this happens from the application  point of view

Have you encountered this type of an error ?? If so what would cause this ?

Kindly advice
