Data is showing incorrectly in a system
Diagnose whether incorrect data originates from the source system or HighCohesion's transformation logic.
Step 1: Find the event and compare payloads
Go to the relevant stream in the Control Panel and find the event
Open the event detail view — you'll see both the inbound payload (what HighCohesion received from the source) and the outbound payload (what HighCohesion sent to the destination)
Compare the two payloads for the field in question
Step 2: Identify where the error is
If the wrong value is already in the inbound payload: The problem is in the source system. HighCohesion passed the data through as received. You'll need to correct it at the source.
Fix the data in the source system
If you need the event reprocessed, fix and resend or request a bulk resend depending on volume
If the inbound payload is correct but the outbound is wrong: The problem is in HighCohesion's transformation logic — a mapping, formula, or field rule is producing the wrong output.
Do not resend the event yet — it'll produce the same incorrect result
Contact the HC team with the stream name, event ID, the field affected, and what value you expected
HC will update the mapping and confirm when it's safe to resend
If you're not sure: Share the event ID and both payloads with the HC team and they'll diagnose it.
