Helper IIIService Refresh timing out
Hello,
Im having an issue with a single page report that refreshes once per 24 hrs in the early hours of the morning timing out. It is a very small data set so I am wondering what the problem may be. It uses 4 entites in Dynamics. In my model, each only has a couple of colunns and even rows is small so Im struggling to see how this could ever be hitting the 1GB limit / timeout. Is there anything else I am missing in settings or setups?
Ok the issue is not about the size of the model, the error suggest reducing the size because it's usually one of the reasons for a timeout. The error message sounds like the problem it's that the refresh process takes too much. It can be an issue in the Power Query transformations (steps or connector) or the Dynamics Server instance is not responding fast at some time in the day. Some connectors will let you have a parameter of timeout like Sql.Databases. I'm not familiarized with the one you are using right now but that might help. If you can increase the timeout connection or command for the query that might help. Even though it's weird that the server takes a lot of time to reply a few rows. It can also be an issue of the dynamics server.
I hope that helps,

Hi. Can you show the error message? timeout it's not only an issue from power bi deta model size, it can be about connection to the source or even the time the query takes to respond. If the data is that small it might be something about the time of connection. Are you connecting to a cloud instance or is it local?
Regards,
richrich123ibarrau , here is the error, it is cloud, as you can see, its a very small dataset. On some days it will refresh ok and others I get failures. We can log a ticket with MS to look into it but just wondered if anyone had any thoughts before that. I can't see any reason for getting these issues with a report with such a small data set thats cloud.
