As a follow-up, I re-added the Gantt group and attempted to delete GtAssignment and GtDependency first, thinking that maybe it was a sequence issue. It is not. They won't delete. But in doing so, I was able to resolve all my integrity problems (after adding a reference to GanttTask that I had added to Appointments, but somehow did not transfer).
If I can't remove all vestiges of Gantt Chart, would the Gantt objects in my business space force me to buy the Gantt license to make this version work or will the Gantt objects just not function in operation and simply clutter my configurator?
I can live with the clutter, but I won't pay for something that I won't use. So I need to know if...
a) it's just clutter and not to worry about a Gantt license,
b) I should go back to a pre-gantt BSV now and redo the work that will be lost, or
c) there a fix that will get rid of the Gantt objects?
Thanks.
