Use the Baselines to Import dialog box to specify which baselines to import when importing a project from a Primavera XML file.
Baseline Name: The project baselines that are available in the import file.
Exists: A read-only checkbox which shows whether the baseline already exists in the database. This checkbox will only show that a baseline exists in the database if you chose the Update Existing Project option in the Import Action field.
Baseline Type: A read-only field which shows the type of the baseline.
Import: Mark this checkbox to select a baseline to be imported.
