SFTP adapter - same file name in receiver

Hi ,

My scenario is  File to SFTP. I have to copy the same file name from source to target.Its a ESR bypass scenario

I know how to do it in  FILE to FILE scenario. But incase of SFTP i dont know how it works.

Surprisingly, i  could not find any help document  for SFTP adapter on Help.sap.com . I have wasted 3 hrs searching for help document but it was of no help. I hve seen almost all the blogs on SFTP adapter but nothing was of help

Can someone tell me where can i find SAP Help docs for SFTP adapter?
