Predecessor Bar Color?

why do u want that. color change happens when you schedule & update project and ur predecessor activity has 

to be completed. also red color indicates critical path activities. whereas green color indicates activities with float.

Hi,

My colleague wants the predecessor to be shown in red bar to show that its critical, as it has to be completed before the sucessor starts. And that the successors will be delayed if the predecessor ends later than sheduled. Is it possible?

Thanks

Thanks Arnold

So we can not define an activity as critical only if it has succesors? Sorry I'm basically new in using Primavera.

Thanks

Hi Anissa,

It only happens when you link between two activities, if the successor activities turn out to be the critical, the predecessor activity will become as well critical which turns the color automatically from green to red if the scheduling option checkbox has been marked next to “Schedule automatically when a change affects dates” it means you don’t need to press “F9” on your keyboard or update manually by selecting Tools Menu --> Schedule… (F9); then select “Schedule”.

However this is not always the case, sometimes, if the predecessor activity may contain one or more successor activities which are not critical and you connect to other activity which is also not critical then the predecessor activity may not be critical.

Critical means if the total float is less than or equal to zero. Total Float calculates the Late Dates minus the Early Dates.

TF = (LF – EF) or (LS – ES),

Where:

TF = Total Float

ES = Early Start

EF = Early Finish

LS = Late Start

LF = Late Finish

Note: Make sure that the Bars Setting is correct and it should look like the below image:

I hope the above assists you.

Hi Anissa,

Absolutely No. If a particular activity does not have any successor maybe at least one or more, it is consider being an open-ended task. And if that is the circumstances, an open-end activity produces an excessive amount of float (slack), as well as it doesn’t drive any succeeding immediate activities, and it measures the amount of Free Float equal to the Total Float if that is an open-end activity.

However, if you mark the checkbox next to “Make open-ended activities critical” under the Tools Menu --> Schedule… (F9); select “Options…” --> General, and then the open-ended activities turn out to be critical.

In the Constructions programme there must be always two open-end activities, the Project Start (No Predecessor) and the Project Finish (No Successor), and the rest there should be at least one Predecessor and one Successor.

Cheers,

Arnold

Thanks so much for the clarification, Arnold!

You are most welcome Anissa.
