Incremental refresh for datasets and real-time data in Power BI - Power BI | Microsoft Learn

Thank you - Much Appreciated. I will go through them.
What is your rationale for shuffling the data from one Azure data storage (BLOB) to another Azure data storage (datamart) ? What prevents you from consuming the BLOB data directly in the dataset?
Hi lbendlin, Thank you for responding
We use JSON files in the Azure Blob, which does not support M Folding. We want to implement incremental refresh which is supported in Datamarts, but not in the Azure Blob with JSON files.
So I did manage to at least save the initial JSON file upload (no data modelling), but the moment I started any data modelling in Power Query, and tried saving, it would crash on me giving the version error or other errors referring to missing columns (columns which actually exist - this makes no sense).
The Power Query in Datamarts appears to be very sensitive and look for things that do not exist.
BTW - these exact JSON files were successfully unpacked on Power BI Desktop and I followed the exact same sequence I used on PBI desktop, but these errors pop up.
