Error refreshing Composite model live connection to Power BI dataset
I have a composite model that combines a direct query to a Power BI dataset in the service with imported data from Excel/dataflow. When I try to refresh in the service to re-import the non-live data I get a connection error related to the live model:
Processing error: COM error: Microsoft.ASWL.Service, Single sign-on (SSO) credential is not provided which is required to execute the current request.. A connection could not be made to the data source with the Name of '{"protocol":"analysis-services","address":{"server":"powerbi://api.powerbi.com/v1.0/myorg/[workspace]","database":"[model]"},"authentication":null,"query":null}'.
Cluster URI: WABI-EUROPE-NORTH-B-redirect.analysis.windows.net
Activity ID: 46425c40-2e48-4091-beaf-76a9e5e82614
I have re-checked the data source credentials and cloud data sources are allowed via this gateway. How can I get past this error and schedule a refresh of the model?

Hello, In my case I am trying to aggregate multiple data sources into one with live connection. So can't avoid calculated table (using UNION in this case) in the final dataset. Any work around? I have confirmed that refresh works if I remove the UNION table from final dataset. Any insight to the error and if anything can be set in tenant or capacity to make this working?

Hello there, same problem over here, any news on the subject?
Thanks in advance!This feature is still maturing, calculate table is not supported. One possible solution is to establish a link table between different live connected dataset and derive aggregation in new dataset. It's slow and inconvient but provides great feature aggregate different legacy data.
I am facing the same issue with the composite model. Has anyone encountered this problem and found a solution?
I am facing the same issue has many of you. I have a composite model. I am then building another model (from that composite model). I tried replicating the main model's date table using create new table because I wanted to test something, and I started getting this refresh error. I deleted that calculated date table (the one I was trying to replicate, not the original one from the direct query table in the source model), and sure enough, my model refreshed perfectly. They say the composite models are the way of the future...but man are they a headache when compared to the simplicity of a pure import model.
I am facing the same issue. I have union tables on both date tables and dim tables. There is no issue to refresh on desktop but cannot pass the error on PowerBI service. Wish there are more documentations around this.

Has anyone got an answer to this from Microsoft? I'm now stuck without a solution. I get exactly the same as above. See details below. Microsoft: a workaround and/or explanation would be fine, please! I need this for an important multinational client.
I get an error message as follows when running a refresh in the Service. It works fine in the Desktop.
COM error: Microsoft.PowerBI.AS.ConnectionDetailsProvider, Single sign-on (SSO) credential is not provided which is required to execute the current request.. A connection could not be made to the data source with the Name of

I have 3 shared datasets joined together with a UNION calculated table joining them together. Without the UNION table, it refreshes fine - there is no credential error.
I have gutted the calculation down to 2 datasets and just one CALCULATE calculation but still I get the error. Only if I have literally no calculations in the UNION will it work.
Storage Mode is mixed, ie. it's a composite table due to 3 shared datasets loaded. - belvoir99
Anonymous I have had the same issue (see other post in this thread). I think I have now found the 'answer'. See this page of documentation on Composite Models:
https://docs.microsoft.com/en-us/power-bi/transform-model/desktop-composite-modelsScroll down to 'Limitations and considerations'. There it states that you can't use Power BI datasets with composite models.
That is what I was trying to do. Perhaps you were also?- belvoir99
Possibly to answer other people's questions on this thread, I will be undertaking the following:
1. Connect direct to the dataflows that deliver content to the shared datasets.
2. Remove any relevant code out of the shared datasets and up into the dataflows.
3. Test like crazy to ensure my numbers are still correct.
I have a long tedious build ahead! 😒
