I need someone to take data turn it in to a power BI dashboard. I need the data to be in power apps and segregated by user account so one user cannot see another users details.
Background
We have 50 different locations.
Some locations are owned by more than client so lets say we have 40 clients
We have reports for each location which need to see individually
We need to see rolled up accounts per client
We need all client reports rolled up in to a single report for us to have an overarching dashboard
Data is in excel and we need it transferred to power BI and a power app. The power app platform will be logged in by each client and, like active directory, they will be able to see the report relevant to them. We need to prevent clients seeing other clients reports.
