I am trying to create a report to include the Work Category field from the time card (screenshot below) but I have been unable to find it in any of the subject areas related to timecards.

As I couldn't find it in a subject area I thought maybe a BI Publisher report would be best but I haven't had much luck with that either. I have managed to find the value set in the HCM_Lookup table but have been unable to link this to any of the other tables relating to the timecard. Does anyone know if it is possible to report on this field and if so how?
