Very curious about this Ancestor (aka parent) and Child Blueprints under one Program.. - I think it would really help our Program, as we need to work off of a "master" project number list which can't have overlapping numbers.
I'm sure someone's dealt with this in other ways.. but not certain how. Did you have one intake for both blueprints? Did you run a report to look for and flag duplicate numbers? Did you just deal with the semi-manual entry of numbers based on a yes/no workflow?
