Why can't I see the participant's transaction?

If the participant isn't the direct participant for a transaction, then the transaction isn't in the list in Manage Transactions.

For example, you see a transaction when viewing a participant in Snapshot, but that transaction is gone in Manage Transactions because it's filtered on the direct participant. A direct participant is listed directly on the transaction. Rules use other information on a transaction to credit a participant. That participant isn't a direct participant. Search for the participant under Manage Credits or Manage Earnings to see details on the base transactions where the credited participant isn't the direct participant.
