i spend quite some time reg. licensing but have still one question. I have server A where i install sql server including ssrs, i have a core based license for this sql instance. Now some of the reports in SSRS use Data from Sql Server B, which has a development license, do i need to change the license of Server B also to be a production license, because i use it's data on a different machine, or is the license of the SSRS server enough? i am talking about Sql server 2016. thanks a lot!
The way you've described it, I'd say yes you need to licence Server B properly. If the reports that you are generating from Server A, based on the data from Server B, are used to run the business in any way, then yes you need to licence Server B as a database that holds production data. It's kind of regardless that you are using SSRS on Server A - you have live data on Server B. But then I'd always say consult your licence authority / software reseller.
