Looking for some insight.
I have three activities A, B, & C. activity B has started and is 5% complete. Activities A & C have finish to finish logic links to B with a 10 day lag. Activity B then proceeds to another activity, say D, with a finish to start logic link. Activities A & C have not started. When I run a schedule update the status indicates that I have progress out of sequence (POS) for activity B. Activity A & C have important output that must be complete before B can be complete. Why the POS?
