Considerations for level addressing

To simplify the process of selecting activities for processing and reporting, use a consistent numbering methodology for level addresses. You can create groups of activities called lists by specifying ranges of level addresses. See Using Attribute Matrix attributes.

For example, you have multiple projects with similar activity structures. Each project is its own activity group and you want to analyze similar activities across different projects. You can use a specific set of numbers in level addresses for meeting-related activities, another set of numbers for development-related activities, and another set related to revisions.

This makes it easy to select related activities within the activity group or across similar activity groups. For example, if you want to retrieve all revision-related activities for a report, then you can construct an activity list selecting activities where the second level address falls between 400 and 499.
