Issue:
Unable to import/save a project back from Microsoft Project (MSP) to Clarity PPM. The following pop-up error is received when attempting to save

"One or more duplicate resources found in Microsoft Project. Cannot save."
Cause:
One reason this happens is if resources are added to the project in MSP. MSP will automatically generate the 'Initials' for the resource as the first letter of the resource names which creates duplicates if you have resources on the team with the same first letter. The Initials field in MSP maps to the Resource ID field in Clarity PPM and must be unique on the project in MSP.
Resolution:
In MSP, go to the 'Resource Sheet' view and check for any duplicate values for the 'Initials' column. For any duplicates (and any resource Initials that do not match the user's Resource ID in Clarity PPM), update the Initials value to the correct 'Resource ID' from Clarity.
