We are not able to set up translations for the discount name in D365. This would be a great improvement because many countries have multiple languages and the same legal entity could have to operate in these languages. For instance, in Canada, Quebec is French but other provinces are English. If you are operating in Quebec, its the law to have the information on the receipts printed in French. If we can't configure a translation then we need to duplicate every discount to have a French and English version for different provinces.
