Sharepoint list relations

Hi sminonese,

Power BI desktop doesn’t automatically pull in related tables for you to choose or load them. If you concern about this feature, please summit your idea on the Power BI Idea forum: https://ideas.powerbi.com/forums/265200-power-bi-ideas .

However, after you load tables, Power BI Desktop will auto-detect relationships when it can , for example, when it finds matching column names and data types between tables, it will display table diagram with relationships in Relationship view.

If Power BI Desktop cannot determine with a high-level of confidence there is a match, it will not automatically create the relationship. You can still use the Manage Relationships dialog to create or edit relationships.
