Thanks for your reply - but why does the passing parameters via the URL doesn't match my scenario? If I load all my data into the Report, I can filter the data by the parameter that the user give via the URL. It is not the native way via the dashboars, but I can use reports as links or embedded web ressources.
Yes, RLS is a way, but the consequence is, I must reproduce the whole security model from CRM in the hirarchy and the roles from the CRM ...
My question is also, does anyone use Power BI in CRM for users with security context? Or I should better use SSRS with XML Fetch?
