If when trying to merge payments in Creditor/Reports/Payment proposal, your payments end up in the Merged payments - excluded' section this is because your payments do not have the required identical information to be merged. The following information must be identical in order for payments to be merged:
- Bank Account number (Inland payments)
– IBAN and SWIFT (Foreign payments)
– Payment ID + creditor account for payment types
– Creditor number
– Currency
