Project Control Tasks (PCTs) align the CCMS with the master schedule for a project that is generated from either a Primavera P6 or Microsoft Project schedule. The CCMS has the ability to link CCMS planned tasks to any P6 activity so that when the CCMS planned tasks are completed, it will automatically update the % complete of the activity. This enables projects to configure an export that generates itself on a weekly basis with updated completions % for any P6 activity that is linked to completions tasks.
A responsible company assigned to the PCT task must first be imported and available for assignment and the company must be assigned a responsibility of "Project Control Tasks".
The responsible company is just the name, not a summary field.
