When saving a project plan from Microsoft Project (MSP) to CA Project & Portfolio Management (PPM), any newly added or updated Team member from the Resource Sheet has their Default Allocation (DA) % updated in CA PPM to 100% and the Project Role field value becomes null.
Solution 1: For new resources added to the project or resources updated in MSP, this would be by design. This data is reliant upon data populated in a reserved field (Text3) at the Resource Sheet level (both Default Allocation and Role are populated based on the values set on the Team tab for these fields in PPM, and when the project is then exported from PPM to MSP, that information is populated and stored in the Text3 field for that Resource. So, the project would have to be saved back to PPM, populate the role and Default allocation in PPM, then export the project to MSP. At that point the Default Allocation and Role for the resource should stay.
For any updated team members, check to make sure that the following fields aren't updated:
