Unique a DFF
We are having a DFF in the customer master, Client enters a unique number for each customer at the creation point.
Client wants this field to be unique. A number which is already entered for a customer should not be entered again to a new customer. There should be a message saying something like "the number is been used for a customer". The numbers entered in the DFF shouldn't duplicate and it should be unique for each customer.
Is it possible to the personalization for the above requirement in Receivables cloud?
Thanks and Regards,
