The Group profile feature makes it easier to manage your work areas. Specifically, you can divide and group tasks into the same group, which makes it much more convenient to run tasks. For example, you have just done both Check out and Reg acc, you will need to create profiles to do check out, and profiles to do reg acc. So now, you use the group feature, group the check out profiles together in the same group, the profiles do the reg acc in the same group.
=> So you have completed the steps to create a group, using the Group Profile feature
