Ok i just read thru a post about relationships from 2008 from another site http://fmforums.com/forum/topic/57413-relation-graph-cardinality-question/.. good information from Comment and David Jondreau. Basically they said that in the relationship graph the straight line indicated relationship to an auto enter field or a validated unique field. The crows foot indicates a "normal" relationship and the pipe indicated a match with an unindexed field (unstored calc, forced to no index, or global) matches that involve a non global pipe are not resolved and a portal based on the relationship is empty. The one instance where the pipe can resolve is to a global. This is true even when their are globals on both sides of the relationship. I used two globals in several tests and it works.. my questions is this... in the real world what possible use is their for a match between two globals?
