These are the steps take-
1. Convert my Excel file into PBIX file.
2. Import my PBIX file to Power BI Service, create a report and pin the report to a new dashboard.
3. Create a role and enter my colleague’s email-address's.
4. Create a rule to define a data filter for Users. [EMAIL] = USERNAME()
5. Share my dashboard to my colleague's.
Overall this has worked, but there are certain individuals who intermittently can see ALL data rather than just their own.How does the Row Levl security fit with AD username and would differences in the email 'Name' or label in AD cause issues?
