If you need to refund a payment for a child invoice that was paid by a parent account holder, you can issue the refund to the parent account and you can choose to also reverse one or more of the child invoice line items to which the refund applies.
Example: If a child account was charged in error you can issue a refund to the parent account holder, then
reverse one or more child invoice line items.
Parent and Child Account Currencies
If you create a child account with parent pay responsibility, the parent and child accounts must be assigned the same currency. This may reduce potential errors resulting from different currency balances being rolled up together at the parent level.

Move Self/Parent Pay MPIs from Dunning when Paying Parent Account Charges
The dunning functionality related to parent-pay master plan instances (MPIs) was changed in Release 41. It is now required that dunning groups are associated with MPIs. So, even if a dunning group is not provided by the client upon MPI assignment, an empty dunning group (one containing no attributes) will be created and assigned to the MPI automatically.
