Performance problems - XML for Analysis request timed out
I have a matrix, let's call it Matrix-A, in my report showing a few, quite complex, measures per customer. It was never fast, but it worked.
I recently made som changes to the report, on other pages than the one described above, with august version of powerbi desktop. I did not change any of the measures referenced in Matrix-A.
Once published in a test workspace I noticed that Matrix-A started to timeout with the error "The XML for Analysis request timed out before it was completed". It couldn't render the matrix.
After that I tried a lot of things but couldn't get it working again without removing a few measures.
Today I downloaded the previous version of the report (which is still working in power bi service), saved it with september version of power bi desktop without changing anything. Published it again under a new name, and now that report also gets the timeout.
To verify I downloaded the previous version again under a new name. Opened it with september version of power bi desktop, changed nothing and published it without saving, and that one still works in power bi service.
That leads me to believe that something has changed with power bi desktop that affects how the reports perform in power bi service. Has anyone else experienced this?
It sounds interesting, perhaps you can try to contact to power bi team with your sample file to help them to confirm if any internal properties/options changes that cause the issue. (e.g. add some timeout check or maximum timeout on formula calculations)
