Reports - Most Recent Things Done on a Case
Case Data > Matter Last Service
Case Data > Most Recent Case Status Update
Case Data > Most Recent Note Time — NB: Fields from this subtable can make a report quite slow. If you only need the "days since" number, use the much faster to load field "Days Since Most Recent Note" available directly on the Case Data table. NB2: All of these fields only look at "true case notes", which does not include notes you see in the Case Notes list like Timekeeping notes.
Case Data > Most Recent Service (service/phase records, not timeslips)
Case Data > Activity (Latest) -- warning: pulling fields from this subtable can make a report slow to load. (Ref: 87135)
