Hi, I have a requirement for locking the fax field in user master records. As you know user can edit the details using the System>profile>own data (SU3), it is causing some security threat to our model. What i want is users should not be able to change the fax field under communications when they get into su3.I have heard of user Exist functionality but don't know how to implement it. Can you suggest something, it will be greatly appreciated.
