Hi Will,
Welcome to this Microsoft Project newsgroup
If your report is based on a Table, then try View/Tables/More
tables.../select the table/select the ID row/Cut Row. However, it would be
best to copy the table first and work on the copy rather than changing the
default table settings.
You might like to have a look at my series on Microsoft Project in the
TechTrax ezine, particularly #21 - Customizoing Tables, at this site:

(Perhaps you'd care to rate the article before leaving the site,

Thanks.)

Hope this helps - please let us know how you get on
