The name of a data group is specified in the name
attribute. The names of data groups that have already been published
cannot be changed. The name of a data group that is being defined for
the first time, can still be edited. Enter the required name in the name
attribute before you save the application. If the name is not entered
in uppercase characters, then it can be automatically changed to
uppercase. However, data group names do not necessarily need to be
uppercase.
