Data Preview not working while creating relationships

[vamshikrishna20]

Hi Everyone, 

I am trying to create relationship between two tables that are connecting to dataflow using direct query. when i try to create relationship in modelling tab, i was not able to see data preview for some reason. Not sure if this is due to large data since my two tables are large with Millions of records. 

Please help me know if there is any other way to reduce performance issues. would like to understand if there's any way to get this data in import mode without any issues.

Hi @vamshikrishna20, 

What type of model is it? Are you using import mode, direct query, or direct lake? 

Direct lake does not preview data.

hello @vamshikrishna20 

if you mean value inside your table by data preview, i believe you can not see in direct query mode as direct query does not store your data inside pbix.

you can see the value using visualization though. or you can summarize all column in new table to see the value.

Thank you.
