In D365 Finance and Operations when you create new leads in the “Sales and Marketing>Relationships>Leads>All Leads” you may face the below error message:
Parameter setup of either language, currency, or type not specified. This is required to create a new prospect.
To solve this issue you must setup the “Sales and Marketing>Setup>Sales and marketing parameters” setup.
In particular you need to fill in the below 3 fields.
- Language
- Currency
- Type
Adding these settings will remove that error message and allow you to save a lead.
That’s all folks. Thank you and keep DAXing.
