How to remove additional carriage return on FTP file?

You could use either XLATE or TCL proc to strip those characters during the translation process of the route.

You didn’t specify how the file is delivered… One think you can check if it is a file or ftp on the outbound is what your message terminator.

Check to see if it is “nl”  vs  “eof”   perhaps the engine is adding the extra line.

Can check this on the inbound too.. to make sure you are keeping the entire file intact as you process through the engine.

If the transfer method is ‘ascii’, carriage returns will be added to the file. Make sure the transfer method is binary.

What David is saying is accurate if the two systems are not the same (i.e. windows vs *nix).  If the two systems are the same then no end-of-line conversion would be made in either binary or ascii mode.  In any case it is going to be best (probably) to retrieve those files in single mode then you can put in a proc on either the inbound TPS or the pre-translate queue that will do a “string trimright” on the message.  Once you have done that then the “whitespace” at the end should be gone and you can add back in the line termination that you need.
