Now, I don't know how to check. I believe it is checked by default or that I had every plan to check it. I know it is using the 10x publishing tools in the background. It is able to package the service definition but it is failing when it's trying to swizzle the data sources from the user to the server connection strings. For our data stores, the connection strings are the same for the user and server. The logs seem to imply it might not be able to find the layer.
