Dear All,

I have this data in P6:

Start Date: 29-Sep-08
Finish Date: 20-Feb-11
Actual Start: 29-Sep-09
Actual Finish:
Early Start: 26-Jun-09
Early Finish: 20-Feb-11
Late Start: 30-Sep-08
Late Finish: 02-Apr-12
Total Float = 324
Data Date: 26-June-09

Strange! Why is the early start 26-Ju-09 when the activity started already? Why is the late start 30-Sep-08 when the total float is only 324?

Please let me know the reason whoever notice the same.

Many thanks,
Scarlett

Dear Arnold,

I corrected myself in my post no. 2. Actual start should be 29-Sep-08.

I thank you for sharing your idea. I think that is the fundamental in P6. Now I understand.

Dear Johnny,

I appreciate your sharing of ideas. Now I will use only start and finish column in P6 so that I will not be confuse since my mind is still thinking like P3.

I thank you all for helping me. More power to you all.

Many thanks,
Scarlett

in p6

ES is not like p3.

ES will be equal to activity’s remaining start or equal to DD once it already progressed.

use the START date in P6 not ES.

LF minus EF equals TF = 324

Hi Scarllet,

Early Start is the earliest possible date the remaining work for the activity can begin, once the activity has started, the Remaining Start is equal to the Data Date. Try to display the Early Dates in your column.

I am wondering your start date is 29-Sep-08 and your actual start date is 29-Sep-09, is this correct? If I understood you the baseline start date is 29-Sep-08, am I right? It means that you are 1 year behind of the target start date? Correct me if I am wrong.

Late Start is 30-Sep-08 and Early Start is 26-Jun-09, if you are going to subtract these two dates considering 7 days a week calendar, you will get 270 days float.

Can you please check again your data?

Regards,

Arnold
