SFTP - RFC Sync Scenario

Hi All,

We have a Business requirement as SFTP to RFC Scenario in Sync mode. We are using SAP NWA 7.4 Java Stack.

Async is working fine, we have verified the data as well in ECC which was triggered by PO system.

Can somebody assist on the same please??

Best Regards,

Sree!!
