Hi,

We have custom object Debrief (Package Name)  field i.e.debrief_notes  of TEXT type and trying to add filter on this field. However, system do not display text type field in data dictionary hence we cannot add filter on this text type field.  I am sharing screenshots.

 

I also tried in ROQL query but failed to get result

Select ID,Incident.CustomFields.Debrief.debrief_notes from Incident Where CustomFields.Debrief.debrief_notes IS NOT NULL

I got an error message

Cannot use column within WHERE clause: 'debrief_notes'
