** FTP Error - Meaning

29 Views

Hi friends,

We use sender CC as FTP. When we put the file in source directory, the file is not picked up and throws the following error:

-


An error occurred while connecting to the FTP server '192.168.15.19:21'. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 500 NLST command failed'. For details, contact your FTP server vendor.

-


For this, we referred SAP note 821267 Q. NO.: 27, they have given solution as below.

o Q: Which semantics does the File Sender Adapter apply to determine

which files to retrieve from an FTP server?

o A: Up to and including XI 3.0 SP13 the File Adapter will issue an

NLST command (see RFC 959) with the configured source file name

03.03.2008 Page 11 of 16 Note 821267 - FAQ: XI 3.0 / PI 7.0/ PI 7.1 File Adapter

scheme as first parameter to the FTP server. It will try to

retrieve any of the files returned by the FTP server in response to

this command.

Starting with XI 3.0 SP14 / PI 7.0, the File Adapter will issue a

LIST command with the configured source file name scheme as first

parameter to the FTP server. If it is able to parse the returned

result (which is the case for UNIX- and Windows-style directory

listings), it will retrieve any of the returned files. If it cannot

parse the result, it will fall back to the pre-SP14 implementation

and use the NLST command as described above.

We are not able to understand the above answer. Could you kindly explain above to understand ?

Kind Regards,
