You can use the cross reference fields to enter information specific to your operation. There are 10 cross reference fields: Xref-1 through Xref-10. The values you enter for the Xref fields become column headings for fields in the Integrated Planning windows, and can be used in reports.
SOW — If you want SOW data included on the CLIN/SOW/WBS Baseline Report , one of the fields must be labeled 'SOW'.
Distributed Project Function — If you plan to use the Distributed Project function, you must change the Xref-1 field label to 'DISTRIBUTED' in all upper case letters.
