Where to find FTP jobs? (which transaction etc.)

We have a job which runs in background (SM37) and puts a file on the sap server (AL11).

From here a job runs and FTPs the file to another location.

I am not familiar with FTP in SAP, can someone tell me where I can find the job which FTPs this file? In SM37 it is not there, only the job to create the file is there. I have been given a jobname i.e. "$FJ20PHP" but have no idea where to find this.

All help greatly appreciated.

Thank you,
