Data Type of Relationships in Power BI

Vanaja V 20 Reputation points


In the the Knowledge Check of Optimize a model for performance in Power BI, it is said that 'relationships can be created between columns that contain different data types in Power BI Desktop.'
However, the article below says 'The data type for both the "from" and "to' column of the relationship should be the same.'
DataType Can you please clarify this?

    Hi Vanaja V,

    Thanks for reaching out to us on Microsoft Q&A forum.

    The article referenced says they should be the same data type but does not say they must be the same. It goes on to explain the implications if the data types are different. The knowledge check being challenged is asking what is true, not what is suggested.

    If you are still facing any issue, please let us know in the comments. We are glad to help you.
