[Former Member]

Hi All,

In one of my scenario file is picking from FTP server, When monitoring Sender Communication Channel in RWB it is throwing following error

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.

The above error is coming only sometimes

Suggest some solution

Hi,

Refer SAP Note 821267 This happens if the file is missing and XI can't find it to process.

Question 27--FTP Directory Listing Semantics

and 36 --FTP: Adapter Polls More Frequently Than Configured

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 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.

Thanks

Check if you have provided the option as anonymous login in your adapter --> change it to a working user.
