Gateway - DataSource Access to SPN

Hi all,

We are trying to automate the PBI deployments, using the SPN. 

All went well until we have a report which is using on-premises data source.We already having the gateway and data sources setup. But using the SPN once the deployment is done the gateway/datasource is not reachable by the SPN.

Reading the Docs, it say SPN cannot able to install and mange on-premises gateway. But we are not trying to install/manage the gateway using SPN. We are trying to add the user in the data source level.

So far we couldn't able to add the SPN in the data source access. We have created a AAD Group and tried to add but that also not working.

Any ideas much appreciated !
