Percentage of completion(POC)

[former_member195427]

Hi Experts,

               Using CN25/CN27 we confirm network activities based on % completion of work against activities. There are several activities with different processing time and different resources allocated to them.How does the system calculates the POC of project based of individual confirmations of activities? Is this POC same as the progress chart shown by S-curve?

If dates determine the progress of the project which report/graph shows the progress of project with respect to time & cost in SAP?

Please help.

Thanks & Regards

Experts,

           Please suggest whether we can discuss on it or the thread be closed now.

kindly suggest.

Hi Ankur,

Try this-

1. Use t-code-CNE5. Enter Project details.

2. Select concern Object node.

3. Press Ctrl+Shift+F7

4. Choose appropriate Graphic type.

Hope this will help you.

Hi Pranav,

             Thanks for your post.It clears one doubt of mine.But my actual concern is on getting how the system calculates POC. I search and got the following logic:

IF you have a Project with only 1 activitie. The 100% phisical advance of the activitie is passed to the Project.

If you have a Prj. with 2 activities and both had 100% phisical advance.  The project has 200%? NO!, PS calculated this

Percent complete Activity A = 100 = A-POC
Percent complete Activity B =100    B-POC
Weigth or contribution of A = 30%     A-Wgt
Weigth or Contribution of B =70%      B-Wgt
(The sum of the weigth need to be 100%)

The Project Advance will be A-POC*A-wgt + B-POC*B-Wgt 
This implies =  100*30% + 100*70% = 30 + 70 =100

The weigth is a function of Men-Hours, Cost or Special-Weigth.

This is what i need to know that how the system is calculating POC.

Can you please explain the above given process in a simple way?

Thanks & Regards

Dear Ankur,

Here PS is following weighted average method.

Percentage completion depends upon weights of work and their completion.

I think this was also clear to you.

What I suggest is to use simulation feature or dummy server for a test cycle.

You will understand the mechanism.

Thanks Pranav. After some testing I will repost here.

Hi Ankur,

I think our query is too broad.

You need to read the sap help on progress analysis to get a better understanding first.

There are different methods for measuring POC , duration, work, milestone etc.

Hi Saurabh,

                 I read for measuring POC in detail but could not get to know about the mathematical calculation done by the system in calculating it. Also, I searched more and got the following (typical to understand ) method:

IF you have a Project with only 1 activitie. The 100% phisical advance of the activitie is passed to the Project.

If you have a Prj. with 2 activities and both had 100% phisical advance.  The project has 200%? NO!, PS calculated this

Percent complete Activity A = 100 = A-POC
Percent complete Activity B =100    B-POC
Weigth or contribution of A = 30%     A-Wgt
Weigth or Contribution of B =70%      B-Wgt
(The sum of the weigth need to be 100%)

The Project Advance will be A-POC*A-wgt + B-POC*B-Wgt 
This implies =  100*30% + 100*70% = 30 + 70 =100

The weigth is a function of Men-Hours, Cost or Special-Weigth.

Can you please explain the above given process in a simple way?

Also, how can we come to know the progress of my project and the remaining work against various WBS within a project?

Please suggest
