Scenario:
User gets the following error when trying to import Projects using CSV Import into Web Resource. Record 1 Warning: Unable to assign type "" to project PROJECTNAME

Cause:
While importing project data into Web Resource using .CSV import, among the other fields, a mandatory field named Outline_Level has to be populated. If this field is not populated, then the above mentioned error message shows up. This error would be returned only for the first project listed in the CSV file, however the import would fail for all the projects in the file.

Resolution:
Make sure to populate the Outline_Level field with the numeric value 1. This has to be populated against all the project names listed in the file.
