Summarize distinct child records by a text field

Yes, but the reasons are recorded on the child record in text format in a field 'Reason not processed'. Each child record has a field called SvcOrderLine# which if unique will determine which child records to count. But in the child table itself, the line record is not marked as unique. While I can do a distinct count of unique child records, how do I do a distinct count of each 'Reason not processed'?

To clarify by counting the reasons, I assume i will know by reason description the count.
1. PWO only - count
2. Locked by user - count etc.
