Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

hello all ,

i'm working on a big schedule it's about 20,000 activites  and by updating it
i usually notice that  for some linked activtes package  the activity total float is increasing by decreasing the remaining duration for the activates .

i will explain  it more as there is progress on site i update the progress percentage complete for the activity and also decrease the remaining duration ( physical type) and then the finish date for the linked activites shifted to be more than the current date instead to be less 


noting that i don't use leds or level of efforts activites and neither SF relationship  (only SS and FF  or FS relationships)

and the activites don't have any ONGOING OR NOT STARTED predessesor only the relationships between them selves 

thanks in advance

1. 1st update the activites that have started with actul start dates but not finished and put in the remaining duration for each of those

2. If activites here started before and have now finished put in the actual start date.

3. If an activity has started AND finished put in the actual start AND actual finsh date 

4. Press F9

5. Chnaae the dated date to reflect the date that you are recording progress thru

6. Analyse results

20,000 activities schedule is for an experienced scheduler.

Are you updating the schedule or you mean revising current schedule version?
