How to do a combination of two fields and define this combination as unique



Book about MDM has text

"A customer number can be assigned only once and should therefore be defined as a unique field. For the banking information, on the other hand, the combination of account number and bank number must be unique, and not just the individual fields themselves. In this case, the combination of the two fields would be defined as unique."

How to do it?
