Getting an error when creating a datamart "the specified connection name already exists"

[VictorSaavedra]

When building a datamart using Import data from SQL Server, using a Gateway that works for the person that created it, I get the following error even when this is the first datamart I'm creating:

the specified connection name already exists. Choose a different name or refresh the list of your available connections. Session ID (xxx, Region: canada)

The main difference between my co-worker and I is that when he selects the Server, the Gateway is immediately selected, whereas I have to choose it from the only option (same gateway). I am also an Admin user.

Please help!

Thanks very much for your response, it was decided not to pursue the Datamart option as it is still in Preview mode.

Hi @VictorSaavedra,

If you clear your browser cookie and try again, will the error be removed? If you create a new datamarts in a new workspace, will you see the same error?
