Hi Melinda, My guess is that because an OpTask can be under either a Project or a Task (so, two optional, 1:0 or 1:1 joins, from a cardinality perspective), the legacyOpenOpTasks was invented in the (older) API to help find the Open Issues more easily. And would add...high five again on the Team Effort a moment ago...that just because we haven't found it yet doesn't mean it isn't there. Regards, Doug
