PowerBI API Update Dataset Schema

[bhalicki]

Hi,

I am expermenting with the PowerBI API.  I want to create a new dataset and push data into the dataset.  This all seems to work fine.

The problem I have is when I try and update the schema (add a new table, rename an existing table).  I have been able to update the name of columns within an existing table, but the documentation doesn't seem to mention anything about renaming or adding new tables to an existing dataset.  Issuing a PATCH (https://api.powerbi.com/v1.0/myorg/groups/{group_id}/datasets/{dataset_id}) and specifying the dataset ID returns 200-OK, but no actual update has been made.

Hoping someone can confirm if it is possible to update an existing schema?  If not, this would be extremely limiting.  Recreating the dataset is one option, but that would involve updating/recreating any of the reports using the existing dataset (not a viable option).

Thanks,

Ben.
