Dataset / Semantic model refresh fails: Type mismatch

[lukmtb08]

Dear community, 

the scheduled and manual dataset refresh of a report always fails with the follwoing error description: 
Data source error: The following system error occurred: Type mismatch. Table: X

When I refresh dataflows, refresh dekstop and publish the report, it works perfectly. But then, the dataset refresh fails again. 
Do you have any ideas? 

Thanks for your support.

Hi @lukmtb08 ,

You can follow this step:

1. Check Data Source Schema: If there have been any changes to the schema of your data source (e.g., column data types, column names, etc.) after your initial report development, make sure these changes are accurately reflected in your Power BI model. Schema changes are a common cause of refresh failures.
