Why are the revenue from export file not equalling to revenue in Analytics display?
I want to find transaction ID that are generated by google / organic;
1. I go to ACQUISITION -> All Traffic -> Source / Medium, It's show revenue by Source / Medium channel.
2. Then choose the Secondary dimension to Transaction ID, the report change to based on 73.33% of sessions
3. After that export this report data. Sum of revenue from export file more than the revenue from first (1.) step,whereas number of Transaction ID (sampling data).
