Datamart authentication blank on takeover

[mylesk22]

we have started using datamart with premium (PPU) as a way to solve our data issues

a colleague set up the datamart using previous queries I have access to, but when I take over Data source credentials will not authenticate

I have access to all the source files (I initally set them up, and works in data flow) but when I try to authenticate the box is blank and will not let me sign in (tried skip test, sign in etc)

tried the normal log off and on again / reboot / edge instead of chrome / googling but cannot find an answer

has anyone experianced this, or know the issue?

Thanks, yes, was the same with flows, but I cannot re enter autentication method (same for colleagues when they take over, but OK for orginal owner only)

I will look a ticket as advised, thanks

Hello, 

did you find a way to authenticate or get any response on your ticket?

Thanks!

When you take over a dataset (or datamart in your case) the cedentials will all need to be re-entered. That is by design (and rather annoying).  Datamarts are a relatively new feature, I would not be surprised if they hadn't tested that part yet. You can raise an issue at https://issues.powerbi.com .
