I am guessing this is like likely not possible (currently) within RM ui
I would like to create: Report / view or group - Siblings born < 9 months apart (excluding born same day as those would be twins etc) .
Purpose is to find siblings whose DOB are either wrong or maybe attached to wrong family.
Other than running an outside consistency checked (like MyHeritage does for example) I am not aware to do this with RM. I suppose SQL is a potential option but not sure who run a comparison that way (Maybe a sort of recursive type qry). Has anyone done anything like this with RM? and if outside of RM – what tool(s) did you find work best for siblings too close.
