Creating a Ribbon Based on a Period Delimiter
Use the Delimiter command to create ribbons based on a period delimiter.
This is useful when needing to create ribbons from a WBS or a hierarchical code field that uses delimiters to designate separation of sections (and level) within a hierarchy. You can select between 1 and 10 levels and choose to include parents in the hierarchy as separate ribbons.
