Question:
When a payment is returned, is there a way to have the Purpose field automatically populate with our internal information so we can link the return with the initial payout?
Answer:
The Purpose field is internal to COS and isn't part of the NACHA format, so the information in it won't be included in the payment to the Receiving Depository Financial Institution (RDFI).
You can however, query the original outgoing payment. It will contain the reference data you populated because COS automatically links returns to the original entry.
You can also correlate the 2 transactions by originator-receiver and the amount.
