couldn't load the data for this visual

[Anonymous]

I have a report that uses a DirectQuery connection to an on-premises SQL Server via Enterprise Gateway. It was working fine throughout the development cycle but after making a few adjustments and re-publishing, the report starting throwing an error "Couldn't load the data for this visual" in the service. Undoing the changes didn't fix the error. The tab in question contains a Table viz and that table contains 21 fields. I found that removing some of the fields resolved the error, but through experimentation I found that it was not any one specific field causing the problem. So I tried rebuilding the table from scratch and publishing after each additional column was added and got it to work with all columns again. Then I started applying formatting changes and found that when I changed the summarization for a percentage column from 'Sum' to 'Don't Summarize' it was triggering the error. Here is the syntax:

Couldn't load the data for this visual

I am having the same problem. Did you ever find a fix?

I have changed the PC that the gateway was running on to one that has never had Power BI gateway installed on but still no luck.

Thanks,

This was not a gateway issue. I believe it was a DAX issue related to DIrectQuery. I ended up creating a view in the database to perform the calculations rather than relying upon my complex DAX expressions. There are so many limitations with DAX when working through DirectQuery and I hope this is addressed by the Power BI team soon. If you use this workaround let me know on this thread if you had success.

I'm starting to wonder if there's a limitation behind the scenes with the Power BI web service.  I'm having a similar issue - visualizations failing to load that contain a few DAX measures - and they render on the desktop app without an issue.

Hi, I am facing the same issue with direct query  and it  has turned out to me that it is because of one million result set limitation on query in dircet query mode.

Just  want to know the work around  in case quering around 10 million of data is the utmost requirement?

Hi @Anonymous,

According to my knowledge, the above error could occur when the previous gateway is not uninstalled completely. You can use CCleaner to clean up registry of gateway, manually delete gateway folder under C:\Program Files, then install the latest version of gateway again and check if the issue still persists.

Thanks,

I had previously worked around this issue by re-building the report in question but the problem has since come back. This time I tried the remedy you prescribed below but to no avail. On top of that, the old gateway did not get deleted -- it continues to appear under Manage Gateways where it displays the message "The gateway is either offline or could not be reached." So now I have another problem to solve.

When I first encounteed this error, I found that eliminating several fields from the table visualization "fixed" the problem. With my current encounter I was able to identify a single field that could be eliminated to make it work. This field is required to be in the table though and a means must be found to add it back without error. What is also strange about this error is that it was not present when the report was published yesterday (I tested it in PBIDC) but today the report was broken.

Based on my experience and the other forum postings with this error, I'm convinced that the problem is endemic to either RLS, DirectConnection or the combination of the two. If you would be so kind, please suggest remedies to 1) Fix the original error and 2) Fix the extraneous gateway problem.

Thanks

P.S. I'd like to add that though it did not say to do so, I first uninstalled the original gateway. When I went to reinstall I was given the option to repair an existing gateway or install a new one. Since I had uninstalled the original by this point I chose to install a new one.

@Anonymous Looks like in your case data format that your visual requires in is not supported by the version of your gateway. So as it suggests upgrade to the latest version of gateway and see if that resolves the problem.
