Bank acknowledgement file configuration in SAP ECC (Response File)

Hi Experts

We have configured new DME format for bank and now we have to configure bank acknowledgment file which we will be receiving from bank after the payment made by the bank for the invoices.

I have tried below steps for the configuration.

I have configured 1. Activate Business Function in Tcode FIN_FSCM_BNK, 2. Map External Status to Internal Status

and I am not getting how to configure 3. Define Logical Directory (Tcode-FILE)

please provide complete information on FILE transaction and how to configure in SAP.

Are there any other steps to configure for bank acknowledgement file.

Thanks & Regards
