Beskrivning

When making a new connection to Salesforce Marketing Cloud from Tableau Desktop, the connection may fail with error code B19090E0 and the following message:

An error occurred while communicating with the Salesforce Marketing Cloud data source 'Salesforce Marketing Cloud'
Bad Connection: Tableau could not connect to the data source.
Error Code: B19090E0
For input string: ""
Unable to connect to the Salesforce Marketing Cloud server "Salesforce Marketing Cloud". Check that the server is running and that you have access privileges to the requested database.
Connector Class: cdata_sfmarketingcloud, Version: 21.8272.0

 

Cause

Salesforce Marketing Cloud (SFMC) now enforces MFA to connect.

 

Lösning

Salesforce Marketing Cloud requires further configuration to allow connection with Tableau.  

Specifically, the "Enable Username and Password for Web Services" must be enabled by an Administrator in Salesforce Marketing Cloud (SFMC), per the extension gallery documentation for the Salesforce Marketing Cloud connector.
