TRM Correspondence Definition

Hi Experts:

I have customized the correspondence so that any time a transaction is settle it prints a documents or send an email. In this case the documents has payments details and the structure of the transaction.

But if the transaction has a decrease in the amount due to a previous payment of the principal and or the interest or a new other flow, how do I get the correspondence of those specific flows (i.e in money market a 1110 Decrease 1200 payed untill due date or a 5001 other flow axes)

thanks in advance

Regards

Claudio
