data flow times out during creation

[AliSafa]

Hi Folks,

I'm getting time-out error while I put a sql code in the advance option in the dataflow creation window.

I put even 180 minutes for the command time out option but it fails after about 15-20 min.

does anyone know how to resolve it?

thanks

Hi @AliSafa ,

Could you tell me what kind of capacity your dataflows are? I think this may be caused by insufficient capacity. There are two kinds of capacities in Power BI, shared capacity(Pro) and dedicated capacity(Premium).

Microsoft allocates different amounts of resources for each level of capacity.

There are limitations on resources in different capacity. When the rescoures are not enough to support you to refresh or send query to local and load data, Power BI will return error.

For reference:  Microsoft Power BI Premium whitepaper

Since all the users of Power BI are sharing the same set of machines (also referred to as the “shared capacity”), controls are in place to make sure that a few users cannot monopolize all the shared capacity in the cluster and disrupt the quality of service for others. Many of the published restrictions of Power BI, like the 1GB model size or the limitation on the number of refreshes per day, are driven by the need to secure excellent quality of service for everyone.

Premium —— dedicated capacity will make us exceeding the limitions like amount of v-cores, RAM,refresh times in one day... and so on.

There is a big difference in resources for different SKU's Premium.

Hi @AliSafa ,

As far as I know, this issue should be caused by the limitation of the shared capacity. You can try again at a time when the capacity workload is low.

You may refer to my above reply to learn more details.
