When do we use “Store Period Performance” function?

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.

  1. When in Enterprise structure there is a ‘calculations’ tab that allows us to set Actual Units or Cost by choosing to “add actual to remaining” or “subtract Actual from At Completion”. This function tool will present correct status when input correctly, + or – to baseline. This actuals update needs to be logged prior to re calculating, (F9).


  2. Hi, I’m curious about your non-labor units. What is the unit of measure? Do they calculate differently than labor units? For instance can they automatically record actuals each period based on physical percent complete?


    1. Hi Terry,
      The unit of measure is hour, just like Labor units. There is no difference.
      It is just a habit that I use non-labor in this case. You can use labor. Nothing is different.
