I am getting this error when I try to drag one of the measure/dimension on to the visual pane. The tableau server is connected with the SSAS database. I have installed the latest ole db drivers for the server. But the Polybase seems not to start. TCP/IP is enabled still the Polybase is not starting and I understand that it's required for cross-platform data access, but not sure if it is the case being here.

An error occurred while communicating with data source 'Model (TabularProject2)'

Bad Connection: Tableau could not connect to the data source.

Error Code: A7AED4D2

Unknown error communicating with data source (COM:0xC1010000)

SELECT

{[Measures].DefaultMember} DIMENSION PROPERTIES [MEMBER_UNIQUE_NAME],[MEMBER_CAPTION] ON COLUMNS,

NON EMPTY ['Customer Details$'].[Customer Names].[Customer Names].AllMembers DIMENSION PROPERTIES [MEMBER_UNIQUE_NAME],[MEMBER_CAPTION] ON ROWS

FROM [Model]

What should I do now?

  • We've recently started seeing the same error codes but with a different process. I wonder if it's related to a recent SSAS patch. – Justin Cervero Mar 21 '21 at 16:18
