Hi,
I'm new to PowerBI. I'm working on an application that has a star schema data model.
In the facts table I reduce the number of rows by filtering data by year, right now I'm loading only the last three years of data.
I would like to reduce the size of the dimensions tables - just loading data for existing facts.
Is it possible to reduce data in the dimension table? I guess it should be something equivalent to left join without merging tables
Regards,
Vitalii

Hi,
take a look at attached file. I merged Dimension right outer
and then removed the merged column of tables in Dimension.
