Symptom
When files are uploaded in the system without MICR number in customer master data, the system isn't working as expected (matching documents).
Environment
SAP S/4HANA Cloud Public Edition
Cause
MICR encoding is the ‘bank routing number’ and ‘bank account’ of the customer making the payment. It is required for correct posting of payments.
When the bank file includes the invoice to be paid (record 4), it is possible to get the customer from the invoice. But not always correct in the case where multiple customers can have the same invoice number.
If file does not include any invoices. Customer can not be found without MICR or invoice.
Resolution
This is SAP S/4HANA Public Cloud standard behavior.
