Hello tugar,

Could you please try following and let me know if this helps.
Code:
awk -F, '{A[$1 FS $2 FS $3 FS $4 FS $5 FS $6 FS $7 FS $8 FS $9 FS $10 FS $11]+=$12} END{for(i in A){if(!A[i]){print i} else {print i OFS A[i]}}}' OFS=", "  Input_file

Output will be as follows.
Code:
ABC, 12345, TEST1, BILLING, GV, 20/10/2012, C, 8, 100, AA, TT, 100
CDC, 54321, TEST3, BILLING, VG, 10/11/2012, D, 9, 99, BB, AA, 99
AAA, 34535, TEST1, BILLING, CC, 12/09/2011, C, 9, 99, BB, CC

EDIT: Adding a non oneliner form for same.
Code:
awk -F, '       {
                        A[$1 FS $2 FS $3 FS $4 FS $5 FS $6 FS $7 FS $8 FS $9 FS $10 FS $11]+=$12
                }
         END    {       for(i in A)      {
                                if(!A[i]){
                                                print i
                                         }
                                else     {
                                                print i OFS A[i]
                                         }
                                         }
                }
        ' OFS=", "  Input_file


Thanks,
R. Singh

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
