When trying to save a project back from MSP (Microsoft Project) to Clarity PPM, receive Project Save Failed error.
Reviewing the app-ca.logs, error indicates issue related to a summary task having an assignment:
ERROR 2019-02-25 13:24:06,577 [https-jsse-nio-443-exec-18] niku.schedulers (clarity:admin:34851000__1A22A639-091E-4172-BF3F-C481B1BDA9F3:schedulers.postProject) Rolling back transaction: java.lang.Exception: Summary task configure test environment(null) cannot have assignments.
Summary task assignments are not supported in Clarity PPM
1. Remove assignments on any summary tasks in MSP
2. Change the summary task to a child task to keep the assignments on the task
To find impacted tasks:
1. Add Resource Names to the MSP task view
2. Look for any tasks that are bolded (which indicates a summary task) and have a value populated in the Resource column
