I might have a new project and there is (for now) only one thing i need to know for SURE!
I need to know that i can prevent duplicates “on the fly” in the following scenario.
i select a “supplier” (ref table) and next i insert (manually) a invoice “number / text-number”. So can i prevent or warn the user that invoice already exists for that supplier?
This “record” of an invoice goes into a diferent table that the supplier table…
thanks in advance!!! Jorge
