Hi all, I've had issues with this for a bit and thought I'd see if anyone had a solution or could point me in the right direction. On some of my reports, I am blending data from a published dataset on service with a on prem server. If I refresh the report in desktop - no problem. If I publish and refresh with a gateway for the "blended" report - no problem. EXCEPT when the published dataset the "blended" report is using also experiences a update. At that point, service is asking me to add the published dataset in the "blended" report to my gateway.
It prompts me to create a connection for analysis services where the server = webaddress of the published dataset. It asks for windows credential, which I'm a bit confused on as its tied to my microsoft account, but okay I go ahead and enter my windows address (including domain) where it prompts for a map user name connection string to EffectiveUserName. I'm not even sure where to start or what to research to get the correct information to set this up.
Thus far I have been DELETING the blended report from service and REPUBLISHING to avoid having to do this, but its becoming quite cumbersome and preventing my team from using published datasets as a data source. Any ideas??
Hi @IC_SLFLORES
When you create a blended dataset is actually called a Composite model. Now when you connect to your On-Premise it uses accounts in the form of "Domain\UserName", but in the Power BI Service it uses "useremail@domain.com".
So to get this to work you need to create a mapping from the "useremail@domain.com" to "Domain\UserName"
