Ok folks. I have Part & assembly data cards where I have linked variable to serial number. When I add a new Part/assembly file or copy it in vault from the outside., after copying data card shows the incremented value for the serial number even if I don't check-in a file. So my requirement is serial number should not be incremented by just adding or copying the file. It should be incremented only after check-in of a file.
Reason for this is: Suppose user adds a file and delete it without checking then after adding 2nd file it will take incremented value. So the previous record will not be found in the vault.
