Try this instead:
Code:
#!/bin/ksh
get_data()
{
        while IFS=',' read fname dfrmt uname serv occr fpath toclient
        do
                DT=$($dfrmt)
                ssh ${uname}@${serv} -n "ls -lrt ${fpath}${fname}*${DT}*" | awk -F' ' '{print $6"-"$7"-"$8","$5","$NF}' | awk -F/ '{print $1""$NF}' 1>>xyz.txt
        done < abc.txt
}
get_data

Having IFS set to "," when you issued the command DT=`${dfrmt}` kept the space between "date" and "+'%Y-%m-%d'" from being recognized as a field splitter (so the entire string became a command name instead of date being a command name and +'%Y-%m-%d' being an operand for the date command.
