Code:
awk -F"[\t,]" 'NR==FNR{if (NR==1) {print $0;for (i=1;i<=NF;i++) { d[i]=$i } } else {line[$1]=$0;next }}
{if(FNR==1) {for (j=1;j<=NF;j++) { gsub("\"","",$j);c[j]=$j;}} else {
if ( line[$1] ) {
for ( x=1;x<i;x++ ) {
for ( y=1;y<j;y++ ) {
if (d[x] == c[y] ) { flg=1;printf $y"\t"} else { flag=0}
}
} if ( flag == 0 ) { printf "NA" };printf "\n";
} }}' master slave

Its not working pravin. Smilie The values from slave file are not placed under correct headers. Also values from master file are not displayed.

If you are trying with data other than which you attached here, our code will not work. we noticed in last 2/3 thread of yours that you are giving sample data which is completely different from your actual data.

You may want to adapt this proposal - which works for your sample data - to your master and slave files:
Code:
awk -F, 'NR>1 {$2=$2 OFS "NA"; print}' OFS="\t" file2 | cat - file1 | sort | tr '\t' ','
1,abc,blr|chn|dlh,500|600|700
1,abc,NA,500|600|700
2,xyz,hyd|blr,888|999
2,xyz,NA,111|222|333
3,mno,blr|hyd,111|222|333
CUST_ID,Name,Place,acc_no

EDIT: sort -n will bring the header to line#1...
