Generate Serial Number for Portal records
I've a question about generating serial number for portal records.
There is a way portal records generate serial number and store it by parent table?
for example if I have record 1 which has 10 portal records, I would like to display 1 to 10 serial numbers on the portal records, and for record 2, instead of continuing with previous records serial numbers, I would like to restart the number from 1 again.
Any thoughts? Thanks in advance.
