Cheers, Ian - much obliged. It does seem to be another minor but irritating bug with which to grin and bear.
This is a bug in P6. In theory LOEs should never be critical since they dont drive anything but in P6 LOEs come up as critical quite often. From the knowledgebase:
"LOE activities are summary-type activities and do not drive the schedule. Because of this, Project Management will never mark an LOE as critical, even if it fits the definition under Scheduling options".
I have not noticed that this causes other activities to become critical as well but I usually filter out LOEs when I am doing critical path analysis.
I have also noticed that LOEs will have an incorrect late start date when they are in progress (it gets set to the actual start date), which may be a related bug, particularly if you are calculating float off of start dates.

Dear Adrian,
It would be best to try to understand one step at a time. You need to identify all the relationships and the dependencies and take one case and try to analyze it and see what happens. Most probably you have an error in these, that is why you have difficulties in explaining the results.
Following the critical activities and the noncritical activities with some float is not too difficult. The constraints and relationships makes it more difficult.
Take one reporting cycle and try to familiarize yourself with the Program at the start of the cycle and do all the updates as per the daily reports. Then try to check if you get the same update at the end of the cycle as per the results of reported.
Depending on the size of the program, maybe you can recreate it and try to take it one step at a time.
With kind regards,
Samer
Dear Samer,
Thank you for taking the time to reply to my post.
This isnt a schedule that Im building, rather one that Im analysing. Part of that analysis is tracing critical and near-critical paths in dozens of updates, all of which have many LOEs, some of which contain critical activities.
Any feedback on if/how/why P6.0 flags non-critical activities that get caught up with LOEs with critical activities would be great.
Thanks,
Adrian.
Dear Adrian,
It seems that you are trying to do something. How big is your Program of Works?
It is better to have clearly understood sequence and relationships between activities. Take it one step at a time and keep it simple. Sonuds like the best thing to do is to start over and know exactly what is going on at each step of the way.
With kind regards,
Samer
