You can now add a new mergefield table "Accountmovement" to the payment reminder table to show all account movements to an order.
For an example the participant does a bank transfer but didn´t transfer the whole amount. Or the other way the participant accidently transfered too much.
In Registration - Basic Setup - Wizard a new setting "Enable download / send payment reminder on overpayment in helpdesk" is now available.
Also attached a template for this new table, please feel free to adapt it (the general table structure must not be changed).
Here an example for a payment reminder when too less is transfered
