Hi Roni,
Are you able to resolve the issue?
I am also doing GXS connection using FTP in SAP PO 7.4.
I able to connect and send file using FTP adapter.
But for sender file adapter I am getting bellow error.
Could not process due to error: java.long.IllegalStateException: Error during RETR epilogue: com.sap.aii.adapter.file.ftp.FTPEx: 550 Unexpected reply codeRequested action not taken. Extraction command SNRF: 1508210524AZOY. TIP error: GOFILE - invalid service reference (must be an 18-digit number).(0060)
Thanks.
