How does “Resource curve” work?

How to backup:

From the command prompt (go to ‘Start’ > ‘Run’ > type ‘cmd’ and click ‘OK’) using the format below

exp system/ @XE full=y file= \xedump.dmp log= \exp_xedump.log

Where:

• is the password you used when you installed P6 Standalone or Oracle XE manually.

is the complete path to the folder where the log file and database backup dmp file are to be created (Example: file=C:\PrimaveraP6\backups\xedump.dmp log=C:\PrimaveraP6\backups\xedump.log)

We were taught that the total float is the amount of time that the activity can be delayed without affecting the overall project duration.

And the calculation of the total float is the difference between the late dates and the early dates.

Either the Late Start – Early Start or Late finish – Early Finish. Both should give the same results.

But in P6 you have the option to use start dates or the finish dates in calculating the float.

You have a group of activities which need to be removed all relationship

Instead of going to each activity and click the Remove button, you can select all activity -> right click ->  Assign -> Click on either Predecessor or Successor

Then select all activity and click on Remove button.

Now you can see all relationship has gone.

In Primavera we can define Critial activities by 2 option:

There are many reasons why we should choose Longest Path instead of Total Float. One of the reason is that when our project has multiple calendar.

In my project, I receive updated data from construction team every month. However, they never update data correctly in that period.

For example, this month is December, most of activity they update start and finish within December but there are always some activities which is updated in November or even in October. (They said they forget to update those activities in November so now they update it this month).

In this case P6 will add some more units to November and make your November report wrong. You have sent November report to other parties and it can not be edited. So, the only solution is you move all November “mistake” unit to December.

You can use Excel to save figure of November and December. Then we can have Actual this month by taking December minus November.

However, we can do this right in Primavera.

First in November you need to run Tool -> Store period performance, to storage Actual Units (in fact this is the cumulative actual unit) to November period.

In December you just update as normal. Now you can show the “Actual This Period Units” column. And that’s the data we need.

 How does “Actual units” spread when you use Resource curve

We have an activity which is applied “Back Loaded” resource curve.

When we update progress, the Actual unit will spread just like we plan.

In stead of click on the Plus icon to create a new WBS, we can press “Insert” button on keyboard.

Enter the ID, press “Tab” then enter the name.

We may want to move it left, instead of click on Left arrow, we can use shortcut:

“CTRL + Left arrow” on keyboard.

When we think about Trim data, we usually export and do it in excel. However Primavera P6 also give us a tool to trim data by itself.

After downloading the installation file from Oracle, unzip it.
