Please help.

You can use a simple Unix script with "startrfc" and calling EDI_DATA_INCOMING as user <sid>adm (excerpt - not the full script):
#! /bin/ksh
DEST=<SID>
SYSTEMID=<SID>
USER=<SU01-USERNAME>
PASSWORD=<PASSWORD>
CLIENT=<CLIENT>
LANG=<LANGUAGE>
MSGSERVER=<MESSAGESERVER>
SYSTEM=<SYSTEMNUMER>
GATEWAY=<GATEWAYHOST>
GWSERV=<GATEWAYSERVICE>
FUNCTION=EDI_DATA_INCOMING
PROGRAM=/usr/sap/<SID>/SYS/exe/run/startrfc
LOGONGROUP=<LOGONGROUP>
for i in `ls <directory>`
do
        $PROGRAM -balanced -3 -d $DEST -u $USER -p $PASSWORD -c $CLIENT \
            -I $LANG -s $DEST -F $FUNCTION -g $LOGONGROUP \
            -h $MSGSERVER -E PATHNAME=$i -E PORT=<WE20-PORT>
done;
You can schedule that using cron to run every minute.
You have to take care of:
- not trying to import not-yet-completely-transferred files (we use a certain naming convention such as uploading with a prefixed "tmp" and after the upload is complete renaming the file. This must be done on the FTP sender side however)
- not try to import the same file twice. You may avoid that by setting a lock (tempfile) and check for it each time the script runs. If it exists, exit the script.
