Basing Plans on Projects Imported from Other Sources
Some projects that serve as the basis for a plan may have originally been imported into Vision. If the imported project has more than three project levels, Vision imports the project's entire structure as individual projects. The project and sub-project relationships are determined by assigned project numbers.
When you create a new plan from a project that contains user defined tabs, grids, fields, or mappings, these fields are automatically copied into the plan.
