Power BI Composite Models: Measures in model not working

[InsightBob]

Hi,

I'm wondering if anyone can help me understand an error message?

I've been tinkering wth the composite models functionality,  when i connect to one of my datasets (with direct query), all of the measures within that model do not work and are flagged with the following error message:

"Cannot find data source 'DirectQuery to AS - [DATASET NAME]' in function 'EXTERNALMEASURE'

So far i have:

- Been able to connect to other datasets without issue
- Experience the same issue when connecting to this particular dataset, and this dataset alone using DQ
- Experience the same issue if i publish the dataset to another workspace
- In all scenarios i am able to recreate the measure, by writing it again, without issue and with expected results

DesktopVersion: 2.88.1144.0 64-bit (December 2020)

It feels like an issue with the dataset, i don't understand the error message well enogh to know what the problem is, particularly the EXTERNALMEASURE bit

thanks

Did you figure this out? I'm having that exact issue with a mixed model directquery and excel , sometimes I get some weird timeouts when running on the service ... very strange . 

any pointers?

I am having the same issue. Are you connected to a dataset used in a template app? I was originally connected to a Power BI dataset with a live connection, and as soon as I converted to a composite model, all of the measures on my dataset broke with the same error.

Hi @InsightBob ,

Sorry, I can't reproduce your issue, coulc you describe more information? Connection mode in the original report? The formula of measure? DirectQuery data source relationships? And is the problem in desktop or service?

Best Regards,
Liang
