Thank you, @michoel So it is a control feature? I am trying to wrap my head around this. I suppose that the head of an Accounting Dept could make a certain set available and only that to their employees to create reports from. It caught me aback when rolled out and I cannot say that I like it.

The whole point was to make life easier - if I need 5 reports of a different variety related to sales - I build one "sales" data set, and then put stuff on top of it without having to rebuild my data set every time.

Your say-so makes me feel better about it. I understand it more now. Thank you @KevinJ of Kansas and @michoel!
