Products

• Clarity PPM SaaS
• Clarity PPM On Premise

Issue/Introduction

For one user, one Clarity project or program won't open in Microsoft Project (MSP) intermittently or it takes a long time to open. It hangs on the opening XML step. The below error message is then seen when trying to open the project after the issue occurs:

"The last time you opened <project> it caused a serious error. Do you want to open it again"?

Resolution

1. Check to ensure the below are all compatible with the Clarity version:
   • MSP New Driver version
   • MSP Version
   • MSP Project Updates
   • Framework
2. Check to see if the there are any other differences between the user with the user with the issue and other users (IE VPN, office location, machine setup)
3. See if increasing the java memory limit to 800 using the steps in KB: Set the maximum java memory usage for the MSP Interface helps
4. Reimaging may also help to remove the symptoms 
5. If no issues are found to point to root cause, contact Broadcom support.
