Troubleshooting dataflow issue: get data from dataflow
Effective November 2020:
- Common Data Service has been renamed to Microsoft Dataverse. Learn more
- Some terminology in Microsoft Dataverse has been updated. For example, entity is now table and field is now column. Learn more
This article will be updated soon to reflect the latest terminology.
You might have created a dataflow, but then have difficulty in getting data from it (either using Power Query in Power BI Desktop or from other dataflows). This article explains some of the most common issues that happen when you get data from a dataflow.
Problem: This table is empty
Let's assume that you're getting data from a dataflow (either in the Power BI Desktop or in another dataflow), and you have access to that dataflow. Sometimes, however, when you get data from a dataflow with the above situation, you get a message in the Navigator saying "This table is empty".
This table is empty means the data isn't loaded into the table.
In the desktop tools such as Power Query in Excel and Power Query in the Power BI Desktop, the loading of data into tables happens automatically (unless you disable it). This behavior is a bit different in Power Query in dataflows. In dataflow entities, the data won't be loaded unless you refresh the data.
You have to set up a scheduled refresh for a dataflow, or if you want to just have a single refresh, use the manual refresh option.
Once a dataflow is refreshed, the data in entities will be visible in the Navigator window of other tools and services.
Problem: Can't see my Power Platform dataflow listed
Sometimes, you have a Power Platform dataflow created, and also refreshed. However, you still can't access it from a get data experience. This might be because the account is trying to access the dataflow. However, if the account does have access to the dataflow, another reason can be the type of dataflow.
The error message you receive might be "We reached the end of the buffer", or "DataFormat.Error: We reached the end of the buffer".
Only analytical dataflows can be used in Get Data from a dataflow experience.
If you've created a dataflow that stores the data into Common Data Service, you can't see it using Get Data from dataflow experience. You can use Get data from Common Data Service instead, to get data from standard dataflows. Or you can create an analytical dataflow instead, and then access it through Get data from a dataflow.
Problem: Can't have a DirectQuery Connection to the dataflow
If you intend to use the dataflow as a DirectQuery source, then you might need to enable it first.
The enhanced compute engine settings are disabled.
Enable the enhanced compute engine, and then you'll have the option to connect to the dataflow using the DirectQuery option.
