Non-work Time Inherited from the Base Calendar Is Not Applied to the Project Baseline (Doc ID 3009232.1)

Last updated on JUNE 05, 2024

Applies to:

Primavera P6 Enterprise Project Portfolio Management - Version 21.12 to [Release 21.12]
Primavera P6 Enterprise Project Portfolio Management - Version 22.12 to [Release 22.12 to 21.12]
Primavera P6 Enterprise Project Portfolio Management Cloud Service - Version 23.1 to 23.7 [Release 23.1 to 23.7]
Information in this document applies to any platform.


The Labor Units of the Project Baseline (‘BL Project Labor Units’) are spread over the whole duration of the Resource Assignment (from the Start date to the Finish date of the Assignment) by ignoring the public holidays inherited from the base Calendar of the Resource Calendar of the assigned Labor Resource, i.e. the ‘BL Project Labor Units’ are spread over 5 days per week (Monday – Friday) independent on the public holidays of the base Calendar.

Therefore, if an Activity with Resource Assignments impacts more than one month, then the Project Baseline shows the wrong monthly workloads (‘BL Project Labor Units’ per month), even if the total number of Labor Units is correct.

The Baseline values should consider the Activity Calendar or the Resource Calendar and not ignore selected non-working days from the shared Calendar.

The issue can be reproduced at will with the following steps:

  1. Open P6 Professional.
  2. Open Project.
  3. Create a Baseline.
  4. Assign the Baseline.
  5. Open Activity Usage spreadsheet.
