Salesforce URL connection change
Salesforce data server connections must use a new URL endpoint.
In the Cognos Analytics Administration console, if you have an existing Salesforce data server connection or want to create a new one, you must manually update the URL endpoint from https://login.salesforce.com/services/Soap/u/20.0 to https://login.salesforce.com/services/Soap/u/49.0.

Note: While connections using this editor will continue to work, this connection editor will be
deprecated in a future release of Cognos Analytics. We recommend that you migrate your applications
to use the new connection editor. For more information, see Salesforce connection editor.
