Negative Float on Milestone?

Double check that you don’t have any constraints on the milestone?

Checked already Oliver.

I’m tearing my hair out here...

Please anyone? I’m fairly new to P5 but have not come across this in P3 before.

Thanks
Vicky

Try pressing F5 to refresh the data as someone on the same database might have added something whilst you’ve working.

Thanks again Oliver,

I am using P5 as Standalone.

Any other suggestions?

Cheers

is it a finish milestone or a start milestone?

Hi Anoon,

It is a start milestone.

i’m sure there are invalid relationships as well in the schedule log, try changing it to finish milestone and see what happens, or you can add another milestone (in this case you need to change the logic).

check if some actual date was entered in any of the activity

Hi Sat,

Yes some predecessors have actual dates but I am using progress override?

I changed milestone to finish but float still the same.

Looks like a long nite for me...boss said negative float cannot lah! :-)

Cheers

Thats really tricky

Hi Victoria,

Still having probs? I have found that on very rare occasions that some actual data once entered and then removed (for whatever reason) can remain in the database despite appearing not to. If the job is not too onerous I would be tempted to make an XER of where you are now so you can go back and then take off progress, task by task, up the logic stream, recalculating after each. You may find the oddity this way.
If you do find it, note the task details and delete it. Add it back in as before and retrace the progress back to now. A hassle but no one said detective work is easy...

Look for external relationships to activities outside of your current schedule. Add the Projects column to your relationship tabs. This may show you something. Good luck!
