Issue/Introduction:

When attempting to open a PPM project in Microsoft Project (MSP), receive the following error: Unable to start scheduler - Workbench Create Dispatch error

Steps to Reproduce:
1. Install the Microsoft Project Interface (New Driver or Legacy)
2. Navigate to a project in PPM, and from the 'Open in Scheduler' drop down, select 'Workbench [Read-Write]' or 'Workbench [Read-Only]'
Expected Results: The project opens in Microsoft Project
Actual Results: The following error is generated: Unable to start scheduler - Workbench Create Dispatch error

Cause:

This is due to the 'Scheduler Format' being set on the project as 'Open Workbench' instead of 'Microsoft Project'

Environment:

Release:
Component: ODMSP

Resolution:

Below are the steps to correct the Scheduler Format:

1. Add the Scheduler Format field to the project list page (one time step): 

  • Navigate to the Project List
  • Click the 'Options' icon then 'Configure' 
  • Move 'Scheduler Format' from 'Available Columns' to 'Selected Columns'
  • Click 'Save and Return'
2. Change the 'Scheduler Format' value for the impacted project on the poject list page from 'Open Workbench' to 'Microsoft Project'
3. Click 'Save'
