In Powerbi service the dataset update fails: The key didn't match any rows in the table.
I created a dataflow in tenant "A" under pro subscription. I use the dataflow as a data source in the BI report in tenant "B". Tenant "B" user also has a pro subscription.
Tenant "B" user is added in Entra as guest user in tenant "A" with member role and build role for the dataflow workspace.
In PowerBI tenant "B", under 'Date source credential' connection to the dataflow is succeeds.
After all this, the dataset update fails.
