Constraint planning "as late as possible" needs an end date. Is it possible not to be completed if a milestone is the successor, and take the date of the milestone?

Really, I don't know how to do this. But it seems an interezsting idea. I recirded the request as Ticket #793.

So is it possible to manage these constraints
1) Must start after starting an activity.
2) Can not be completed before the end of the other activity.

1) No, relations are only end-start.
3) Neither.

Only thing you can do is play with priority : higher priority (smaller value) for first one, lower priority (higher value) for second one, and adding a milestone before both, they should start on same time, possibly hte second after the first (because of priority). But this will not be assured.

That's what I thought :huh: ...
In case I hoped a miracle solution 😛 ...
thank you
