If a payment advice note has been sent to the market partner, contact
the market partner to clarify the following points:
Has the market partner already post the incoming payment?
Has the market partner already received a payment advice note?
Has distribution of the payment to the end customer already taken place
as a result of the payment advice note in the market partner's system?
Depending on the processes that have taken place, the market partner
must take the necessary steps - for example, repay the incoming payment
and, if distribution has already taken place, reverse the distribution.
If you need authorization to reverse the aggregated posting, contact
your system administrator.
