timeouts for SQL Analysis Services (client side)

[gckcmc]

I see this thread:

https://community.powerbi.com/t5/Desktop/Query-Timeout-on-update/td-p/53459

does anyone know what the code would be for SQL AS entries?  I tried these options, but the syntax isn't recognized.

It depends what function you are using to pull the data from SSAS. If you are using AnalysisServices.Database() you should be able to specify the CommandTimeout property (see https://docs.microsoft.com/en-us/powerquery-m/analysisservices-database)

So I'm using that interface.  However, no matter what value I choose, I get the "DataSource.Error: AnalysisServices: This function doesn't support the query option 'CommandTimeout' with value XX

= AnalysisServices.Database("mycompany.com", "DatabaseName", [TypedMeasureColumns=true, Implementation="2.0", CommandTimeout=2])

I've used a ton of different values, as the documentation doesn't specify if it's minutes, seconds, ms, or other.  Used with and without quotes as well to confirm.

I'm wondering if the server-side is blocking attempts to override the value?

hmm, that documenation is not very clear on that. When it says "A duration" it means a literal "duration" data type for PowerQuery. You can create one using the #duration( <days>, <hours>, <minutes>, <seconds>) constructor.

So if you wanted a 2 and a half minute timeout you would do the following:

= AnalysisServices.Database("mycompany.com", "DatabaseName", [TypedMeasureColumns=true, Implementation="2.0", CommandTimeout=#duration(0,0,2,30) ])

Thanks!  I'd seen that documentation for non SSAS types, however it wasn't working when I tried it.  There seems to be another format that syntactically is taken, but errors out.  (single number vs. the 4-ple style you list.)
