SEPA Direct Debit receipts

Hello,

I've setup the SEPA Direct Debit receipts and I have one question:

- The SEPA DD receipt file that we need to submit to bank, do we need to do customer by customer or is there a way to select of list of customer all at once to get the same kind of receipt?

In the setup done, the file to submit in the bank is generated in the manual remittance entry (GESFRM function).

However, this implies to create a bank file per receipt and, since its a lot of transactions, there is other way to get these bank files in one?

Thank you.
