Thank you for the response. However, I am not seeking a method to test for data entry errors. As I wrote, I am seeking an internal FTM utility that checks and corrects the structure of the database as have other genealogy software.
Wrong linkages, such as the example I gave where a 1950s individual was linked as the parent of a 1700s individual, is what I need to test for within FTM. I did not make such a linkage. The linkage was present in my FTM database after FTM failed during a compact operation.
