Hi Venkata,
Both ACH (Automated Clearing House) and Wire transfer are electronically transferred payment types including bank to bank transfer.
ACH - High Volume, Low value payments ( Usually not urgent payments)
Wire - Low Volumen, High value payments ( real time urgent payments)
Each bank has its own standards mentioning needed details in payment media ( like IBAN, SWIFT code etc..) for ACH and Wire. Need to configure the payment tree as per guidelines.
Both kind of payments can be configured through PMW with customized DMEE along with OBPM1/2/3 configurations.
Cheers,
