Clarity PPM SaaS Clarity PPM On Premise



When opening a project in the Microsoft Project (MSP) New Driver, task durations are exported incorrectly if the base calendar is not set to 8 hour per day shifts. 

Steps to Reproduce:

  1. Launch MSP stand alone, close all opened projects including "Project 1", go to Options > Schedule > set 'Hours per day' to 7 hours and 'Hours per week' to 35
  2. Close MSP
  3. Set the PPM Base calendar to 7.5 hours per day:
    • Log in to CA PPM > Administration > Project Management > Base Calendars > locate the site calendar marked as "Base calendar"
    • Go to "Edit Calendar Exception" tab
    • Select all weekdays by clicking on the checkbox on the weekday columns: Mon, Tue, Wed, Thu, Fri
    • Click 'Set Shifts'
    • Change the shifts so that there are 7 hours for a day. For instance, set the first shift to start from 8:30 AM instead of 8 AM
    • Save and Return
  4. Create a project in PPM 
  5. Create a one day task on the project 
  6. Open the project in MSP

Expected Result:  Task has a 1 day duration matching PPM

Actual Result: Task has a duration of 1.07, finishing at 9AM the following day


This issue is caused by CLRT-79717/DE33790  




This issues applies to CA PPM 14.2 and higher in the MSP New Driver


This issue as been fixed CA PPM 15.1 patch 6, 15.2 patch 3, and 15.3.


1. Adjust the task duration to match that of CA PPM before saving from MSP


2. Add a dummy assignment to any tasks without assignments


3. Use the MSP Legacy Driver
