How can I count how many Relationships are linked to the Entities / Tables in an erwin DM model?
In erwin DM, Report Designer can get you the report for all the Relationships associated with Entities / Tables by running the report for Parent Entity, Child Entity and Relationship Names. This will give you the names of these objects. However, if you need the count of which Entity has how many Relationships associated with it, then an easier way would be to export the report result set to MS Excel and use the Pivot functionality built in that. Please see the attached document on steps on how to do that.
