The Available Finish date is changing for some resources when saving a project back from Microsoft Project (MSP) to PPM
Steps to Reproduce:
Expected Results: Finish date remains as the project finish date
Actual Results: Finish date changes to the Finish Date of the 100th allocation segment
This issue is due to a limitation with Microsoft Project.
Microsoft Project only allows 100 Availability Units per resource, any allocation segments after the 100th for a resource do not get exported to MSP. This results in the Finish Date for the resource being saved back to PPM as the 100th allocation segment / Availability Unit from MSP.
To prevent availability from changing when saving a schedule back to PPM, limit allocation segments to 100 or less in PPM.
