fixed a lil' "feechah":
Code:
# if the number of fields is 6
NF == 6 {
   # add to running tally of sum the value of the last (NF) field
   sum+=$NF
   # concatenate the current line to the running record of the previously encountered lines of 6 fields
   rec=(rec)?rec ORS $0 :$0
   # go to the NEXT line
   next
}
{
   # if the running record (rec) is NOT empty
   if (rec) {
   # print the 'summary line' (the line with 5 fields) followed by the sum
   # (sum) and followed by ORS (new line by default)
     print sumLine OFS sum
   }

   # reset the sum to 0 and rec to empty string
   sum=0; rec=""
   # assign the current line ($0) to a variable sumLine
   sumLine=$0
}
END {

# take of the trailing record - same logic as before
  if (rec)
    print sumLine OFS sum
}

Have you tried the posted code?
Does it satisfy your requirements?
If not, please identify (with examples - properly quoted using 'code tags') your required output?

not sure whether understand your question clear.

Hope below can help you some

Code:
use strict;
my @tmp=reverse <DATA>;
my($tmp,@result);
foreach (@tmp){
	chomp;
	my @tmp = split;
	if ($tmp[5] != 'SUM'){
		$tmp+=$tmp[5];
		unshift @result, $_;
	}
	else{
		s/SUM/$tmp/;
		unshift @result, $_;
		$tmp=0;
	}
}
print join "\n", @result;

I pasted the code and it works, but there is one small error. It is not printing all the fields in the first line, it only prints SUM alone. Rest of the line all the fields are printed.

Thanks
