Why isn't an event with two dependencies moving the second event when I move the

first event? I'm not sure if I'm doing something wrong, but I've got an event (a pregnancy) with two precursor events (intercourse with potential Daddy A and intercourse with potential Daddy B). If I make the pregnancy dependent only on Daddy A, when I move the date of that event (intercourse), the date of discovery of the pregnancy and the date of the birth of the child move with it. As soon as I add in intercourse with Daddy B as a dependency, moving the date of intercourse with Daddy A, no longer moves the date of the discovery of the pregnancy or the date of the birth. Let alone the date of the intercourse with Daddy B (and it's dependent events). Only the date of intercourse with Daddy A changes. Ideally, I'd like the whole messy web to move when I change one of these events. Regardless, it seems inconsistent.

Hi Rita, When a single event has two dependencies, it takes on the later of the two dates. If we switch to Project Management for a second, imagine: "Plaster Walls" can only start when "Make roof watertight" is completed. But it also requires "Electrical wiring" to be completed. So it is made dependent on both those events. The electrics and roofing are still independent events - the electrician might fail to show up for a month, but that won't stop the roofing guys... So moving one of those events doesn't affect the other, but the plastering can only start when the latest of those events completes. From the description, that sounds like a direct parallel with what you have currently configured. In your case, it sounds like you want Daddy B to move when you move Daddy A, so there are a couple of options: 1) Make Dady B dependent on Daddy A (e.g. Daddy B = daddy A + 5 days) 2) Reverse the dependency between Daddy B and the Pregnancy... i.e. "Daddy B = Pregnancy - 8 months" instead of "Pregnancy = Daddy B + 8 months". To do this, delete the existing dependency, then se lect Daddy B and add it with a negative offset. Either of those configurations will remove the independence of Daddy A and Daddy B, so they all move around together for you. Hope that makes sense. Let me know if you have further questions. Matt

Thanks, Matt! I think I understand what you're say, but I guess I need some examples. I've tried making Daddy A and Daddy B dependent, but they still didn't move together when I move Daddy A (and the pregnancy no longer moved either). And I guess I'm not seeing how to 'reverse' a dependency at all. I believe it's the math part I'm failing at... I'm not sure where or how to enter Daddy B = Pregnancy - 8 months. Or I'm just doing it wrong. I considered putting everything under the same parent, so I can just move the parent, but I'm a little leery that I'll still move part of the series of events (accidentally or intentionally) without moving the other events if I muck around inside the parent. The problem is that the interval between the events is (somewhat) immutable... conception to birth is a definite interval (+/- a few days). Seems like there ought to be a way to say the intervals between two events must remain locked (fixed), even if Daddy A and Daddy B are technically independent of each other.
