Limitations for Power Query OData Feeds in Power BI

One of the features available in Power BI is the ability to take any defined data source and expose it as an OData feed. This is a very simple and quick way to get your existing data available through OData, as it involves a simple check box selection. Complete instructions on setting this up can be found here. There are however a few limitations to what you are able to do that you should be aware of before you head down this path.

Intranet Only

The OData feed feature works through the Data Management Gateway, which is normally used to keep data models stored in the cloud updated regularly with new on-premises data. When a data source is registered, an “enable OData feed” option is made available which when checked, creates an OData feed URL.

When this feed is used, a connection is made directly from the OData client to the Power BI service, which then redirects communication to the Data Management Gateway. The reason that this is important is that because the actual data connection does not go through the Power BI service, the client machine needs to be able to communicate directly with the machine hosting the Data Management Gateway. This means that the OData feed only works on the intranet – it can’t be shared publicly. For now at least.

Data Types

The Data Management Gateway, and therefore the Power BI service don’t support all of the data types supported by SQL Server, or Oracle. If your table or view uses any field that is an unsupported data source, the entire table will be unavailable to use in an OData feed. The table will appear as greyed out when the list of tables to use for OData is being configured.


In the above case, the DistrictMaps table contained a geography field, which is unsupported. A complete list of supported data types can be found here. If you are using unsupported data types, you may want to consider creating views that do not contain these fields, and exposing those.

Data Sources

Up until recently (version 1.2), the Data Management Gateway only supported performing data refreshes from two on-premises data sources – SQL Server and Oracle, which constrained its value somewhat. Version 1.2 brought support for a wide variety of Power Query data sources, which really changed the game. Now, since OData feeds utilize the Data Management Gateway, we should be able to expose all sorts of data sources as OData feeds, right?

Wrong. Well, not quite at least. I received a question from Hrvoje Kusulja,  who was trying to expose DB2 data as an OData feed through Power Query, but the OData feed option was disabled. After some testing, and communication with Microsoft, I was able to determine conclusively that while Power Query queries are supported for OData feeds, the underlying Power Query queries MUST come from either SQL Server or Oracle. This is identical to the Power Query refresh support in version 1.1 of the Data Management Gateway. Unfortunately we couldn’t find documentation on this anywhere.

One potential workaround if you need OData support and your data source isn’t supported would be to use an ETL system (Integration Services) to pump data into SQL or Oracle, and create the query from there.

OData feeds is a great little feature, and a nice side benefit from using Power BI and the Data Management Gateway. As with any new product, it has limits that will undoubtedly be reduced in the future, but it’s important to know where they are.

    I have, and it’s an excellent workaround especially when you’re proficient in SSIS. I thought that it was a little out of scope for this article, but thanks for pointing it out!

    When you say Intranet Only, I believe this means that clients off the network cannot use the Odata feed in power query however they can still review the reports in PowerBI – which can refresh the data using the DMG. Do I have that right? Any word if Odata consumption for clients off network is on the road map?
