Hi @asmagh,

Could you be more precisely with requirement by posting your table structures(including the table relationships and the measures you're using) with some sample/mock data, and the expected result? So that we can better assist on this issue. It's even better to share a sample pbix file which can reproduce the issue. You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading. 

Regards
