Set up a Connection

Prerequisites

The following are the prerequisites to establish a connection:

Service Account User Permissions

It is recommended to use a separate service account to establish the connection to the data source, configured with the following minimum set of permissions.

👨‍💻Who can provide these permissions? These permissions are typically granted by the Tableau administrator, as users may not have the required access to assign them independently.

Objects	Access Permission
Connector Validation	Site Administrator or Explore (Can Publish)
Crawling	Site Administrator or Explore (Can Publish)
Lineage	Site Administrator or Explore (Can Publish)
Delta Crawling	Site Administrator
Workbooks	Site Administrator or Explore (Can Publish)
Views	Site Administrator or Explore (Can Publish)
Sites	Site Administrator or Explore (Can Publish)
Data Sources	Site Administrator or Explore (Can Publish)
Sourcecode	Site Administrator or Explore (Can Publish)

Delta crawling requires revision history permissions to be enabled. These permissions are enabled automatically for site administrators. For the 'Explore (Can Publish)' role, they must be enabled manually.

Users are required to have the Connector Creator role in order to configure a new connection.

1. Log into OvalEdge, go to Administration > Connectors, click + (New Connector), search for Tableau, and complete the required parameters.

Fields marked with an asterisk (*) are mandatory for establishing a connection.

Field Name	Description
Connector Type	By default, "Tableau" is displayed as the selected connector type.
Credential Manager*	Select the desired credentials manager from the dropdown list. Relevant parameters will be displayed based on the selection. Supported Credential Managers: OE Credential Manager AWS Secrets Manager HashiCorp Vault Azure Key Vault
License Add Ons	Auto Lineage Supported Data Quality Not Supported Data Access Supported Select the checkbox for Auto Lineage Add-On to build data lineage automatically. Select the checkbox for Data Access Add-On to enable the data access functionality.
Connector Name*	Enter a unique name for the Tableau connection (Example: "Tableaudb").
Connector Environment	Select the environment (e.g., PROD, STG) configured for the connector.
Connector Description	Enter a brief summary or details about the connector.
Host Name*	Enter the Hostname or IP address of the Tableau server.
