Hi,

We have a problem about matching a supplier payment with two or more supplier invoices. 

Today we send a ISO20022 file to the bank where we sum all invoices per supplier. 
Ex.We need to pay a supplier three invoices with a total amount of 1500 DKK. Today the ISO20022 file will contain one payment per supplier and when some information about invoices no. for these three invoices that will be paid. (this is fine)

When we receive the CAMT053 file from the bank it also only have one payment order for this supplier with three invoices. How can we match one supplier payment in External payment with three supplier invoices?
