Options
Name - Enter a name for the data connection group. Only alphanumeric characters (a-z, A-Z, 0-9)—not including punctuation or symbols—are allowed. Spaces are not allowed (an underscore _ is a good substitute).
Select Data Connection - Use the drop-down to select data connections to add to the connection group. The list contains all defined data connections until a connection is selected. Once selected the list will filter out all dissimilar connections based on driver type.

Groups: Choose any of the listed groups to allow usage rights to the data connection group.
Permit All - Select whether to allow all users usage access to the data connection group.
