Hi all --
We're using PowerBI with the VSTS service integration and last week we started getting an error during refresh:
Column 'Issue Id' in Table 'Parent Issues' contains blank values and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table.
We don't control the dataset and don't have any visibility into the rows causing the errors... anyone aware of a way of figuring this out?
Thanks,
Matt
Hi @MattLavallee,
Could you please describe more details about that what changes you make in Visual Studio Team Services recently? Would you please delete the dataset and re-connect the VSTS content pack, then check if you get any refresh errors?
Thanks,
Lydia Zhang
Hi Lydia,
We actively use VSTS, so it's an ambiguous question to ask what we have changed... We obviously cannot change the data model ourselves as it is a service from Microsoft.
I can't delete the dataset because that will delete all of our reports and dashboards.
Thanks,
Matt
