Time out error while doing ABC classification

Hi Team,

I have been doing ABC classification for inventory analysis in my project.
I followed the link - Power BI ABC Analysis using Window function, Dynamic Segmentation 

The data I am dealing with is coming from three tables- 

1)Dimension_ItemAttributes(437960 records) 


3) Fact Stock (54278) 


I am using Azure Synapse SQL Server as my data source and whenever I try to refresh my data in Power BI service using all the records above, it gives me error- "The XML for Analysis request timed out before it was completed. Timeout value: 18000 sec."

My data is not that huge as it is loading in seconds when trying to do individually, seems to be that the operations (measures and calculations) are taking time and hence the failure. 


Please share your thoughts to fix this. 

Also, the report works fine with limited data(<100000).
