Hi Naresh
There are various options how you can integrate SWIFT into SAP and SAP Correspondance Monitor.
From a full blown SAP blueprint with (SIPS, BCM, PI etc.) to a straight forward, plain vanilla integration.
It is as well very much depending on your SWIFT infrstructure!
What SWIFT setup do you have?
Please let me know - I'm happy to elaborate further.
with best regards
