Hello Alan and welcome to the QlikCommunity!
Groups are not modifiable from the UI when using a client (either it is the Desktop, the IE Plugin or the Ajax). You cannot either create new groups as you cannot access the Document Properties.
If your users want to use new groups they should ask to a developer, as long as it does not require to reload the script, only create the group and save the file, at least for the time being.
But feel free to create an Idea suggesting that feature in coming versions of QlikView.
Hope that helps.
Thanks for the reply.
I know that I can add new groups but with the volume of end users we have I don't want to add too many new groups that everyone can see so that was why I had hoped the users could do it on the server but alas it was not to be.. or at least not yet!
I'll suggest it in the Ideas forum and how knows what can happen.
