I'm just new to P6 and has lots of questions. I hope you guys are patient for me. I know how "BASE %" is computed but not the "Finish". This is not resource and cost loaded. Purely duration. Row "Act % Comp" is manually computed. My question is: How P6 automatically determine my finish date? 

Thanks PP for making me a part of whis group.

Dear Mr. Sims,

I tried your suggestion but I can't get there. Calendar used is 7day work per week that means no holiday. No resource and cost loaded. For example on this sample project I am working now. My data Date is March 22. For activity A1030: Pier 2nd Stage, The details as shown on the image attached:

Original Duration: 48; Actual Duration: 11

Remaining Duration: 38; Data Date: Mar 22; Actual % Comp: 20%, Predecessors: A1020 - SS10 and FF10

You mean, I will add Mar 22 to the Rem. Dur. (38). The Finish Date as calculated will be 28 April but Finish Date in P6 is 07 May 13. Can you tell where I made mistake? thanks.

Thank you Mr. Sims. I will try and see if I get there. Hopefully, I'll get it so I can move on...

hi warren,

this will be dependant on your settings and if you have resource assigned.

if no resources are assigned Primavera will calculate the budgeted days (or hours etc) you set against the actual durations you have applied as actuals, so if you bugeted 10 days and used 4 of those days then you will have 6 remaining.

the 6 days will be as your data date (update date) so if you schedule project (f9) and set the data date to the current date or your update date the remaining days duration will be from that date plus the remaining... this giving you the calculated finish date.

Be aware though that the activity or project you are updating will have a calendar assigned and that may take bank holidays etc in to account.

I hope that helps.

John
