Calculate the Non Work Duration of Primavera P6 Activities

I was recently asked how if it was possible to calculate the non work duration of a P6 activities.

I found it was not as simple as I thought it would be but I have created a Global Change that will achieve this.

Process

The process to operate requires:

• Three User Defined Fields and
• A Global Change.

Three User Defined Fields

On the right, the following UDFs were created.

NOTE: Integers were used to prevent non round durations.

Global Change

On the right, the following Global Change was created.

NOTE: The Original Durations were divided by 8 to convert the durations from hours to days.

Result of the Global Change

The running of the Global Change gave the result on the right.

NOTE 1: The summary bar Non Work Duration of 12 is a sum of the values below and users should consider unchecking Show Group Totals in the Group and Sort form so this is not displayed.

NOTE 2: This Global Change will only work when all the calendars are on a 8 hour per day. If there are calendars with different hours per day then one solution is to create a Global change for each calendar.
