Hi all,
I have a custom object named xyz. It has text fields. The text fields are unique.The user can enter serialnummbers in this text fileds. How can I prevent the users to enter a serialnummber of a devie for obeject xyz 1 and xyz2.
The Users must enter the serialnummber of a device just in field serialnummber of object xyz1 the same serialnummber must not be entered for object xyz2 in field serialnummber.
Now a user can enter 1234 as serialnummber in first field of xyz1 and 1234 in 4th filed in xyz2 as serialnummber and it must not be allowed
Thanx
