I want to trigger warning message if we select same invoice date for same supplier
Hi Team,
I want to trigger warning message if we select same invoice date for the same supplier.
Ex: I have a supplier XYZ,
I raised one invoice to XYZ on 29-nov-2017. And one more invoice am creating for XYZ in Same date 29-nov-2017.
Now I want to populate a warning message "Already invoice is available in this Date"
Please help with code.
Thanks,
Ramesh Nallavala
