File communication channel issue : object name too long

Hi Experts,

My requirement is to place the successful files in folder and un-successful files in one folder after processing.

we used parameterized mapping to achieve this requirement.

I'm facing below issues, please help me to resolve.

" An error occurred while connecting to the FTP server. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 501 Unexpected reply codeSpecified object name too long, limit is 10 characters: $Filepath_Su.'. For details, contact your FTP server vendor.

As per my understanding it is not taking the path specified,because of length issue.

Please send me your valuable inputs and help me.

Thanks in advance for your help.

Regards

Bhargava Krishna
