D365 CSP Licensing

Hi All,

This might seem like a really silly question but I’m hoping someone can put me right. For D365 base licensing on D365 CSP subscriptions, is the minimum of 20 users of a base license only for the first 20 of Finance or Supply Chain? What I’m trying to understand is, whether a customer needing 20 finance and 10 Supply chain would need to buy 20 of Finance and 20 of Supply Chain, or whether 20 Finance and just 10 Supply Chain would be possible under CSP?

Many thanks
