Project codes help you track different projects based on characteristics they share. You can use project codes to arrange projects hierarchically when your EPS contains many projects within many levels. If you have many projects in the hierarchy, project codes help you group and filter potentially vast amounts of information spanning different areas of the organization. The application supports an almost unlimited number of hierarchical project codes and values; you can establish as many as you need to meet the filtering, sorting, and reporting requirements of your organization.
