Have seen this question multiple times in the public forum on how to access the Data Management directly rather than accessing it via the Workspace?
The URL for On-Premise to access the Data Management directly
The URL for PBCS/EPCS to access the Data Management directly
While accessing the above URL if the Workpace is already opened it opens in a seperate tab. If not logged in before opens up in the same tab in IE.
Note: This is applicable to both On-Premise and PBCS/EPCS
