awk script concatenate two column and perform mutiplication
Need your help in solving this puzzle. Any kind of help will be appreciated and link for any documents to read and learn and to deal with such scenarios would be helpful

Concatenate column1 and column2 of file 1. Then check for the concatenated value in Column1 of File2. If found extract the corresponding value of column2 and column3 of File2, Again concatenate column1 and column2 of File2. Now look for this concatenated value in File1 and if found

For example - concatenate column1(262881626) and column2(10) of File1. Then look for this concatenated(26288162610) value in column1 of File2 and extract corresponding column2 and column3 value of File2. Now again concatenate column1 and column2 of File2 and look for this concatenated(2628816261050) value in File1 and multiply exchange rate(2) fetched by concatenated value(26288162610) with taxable value(65) which corresponding to 2628816261050 of File1. Store the result of multiplcation value in column4(AD) of File1 only

I tried below code..but its not working.

awk -F"|" 'FNR==NR{a[$1$2]=$NF;next} {print $0,$1 in a?"|" a[$1]*$NF:""}' OFS="" File2 File1

File1

Code:
 Bill Doc     LineNo     Taxablevalue     AD
 262881626         10        245
 262881627         10        32
 262881628         20        456
 262881629         30         0
 262881630         40         45
2628816261050      11        65
2628816271060      12        34
2628816282070      13        45
2628816293080      14        0
2628816304090      15

File2

Code:
Bill.Doc     Item     Exch.Rate     
26288162610     50     2    
26288162710     60     1    
26288162820     70     45
26288162930     80     1    
26288163040     90     5

Output File

Code:
Bill Doc        LineNo  Taxablevalue   AD
262881626        10       245
262881627        10       32
262881628        20       456
262881629        30       0
262881630        40            
2628816261050     11      65            130
2628816271060     12      34            34
2628816282070     13      45            180
2628816293080     14      0              0
2628816304090     15

In what way "its not working"? Usually, contemplating / scrutinizing misbehaviour and error messages will lead you to the root cause yourself, and the knowledge of either would help others help you as well.

Hi Rudic,
it is not giving any error, but also not producing the desired output and not doing multiplication of column3 of File1 with column3 of file2 and not storing the multiplication result in neither column3 nor column4 of File1..
Pleas help rudic to achieve my output

Well, you define the field separator to be | , but I don't see ANY | in your sample data. Did you consider dropping the -F"|"?

Try as well
Code:
awk 'NR==FNR {EXR[$1 $2] = $3; next} $1 in EXR {$4 = $3 * EXR[$1]} 1' OFS="\t" file2 file1

The third exchange rate seems a bit high and thus leads to a rather high AD value...

Hi Rudic,
Apologies, but actually to have more clarity for sample data i pasted sample file1 and file2 without pipe..though in actual file contains pipe..
for now code point of view you can cnsider space as well

Hmmm - it doesn't really help if you post code and sample data that don't match.
Howsoever, did you solve your problem or does it persist?

Hi Rudic,

Still have problem. getting 0 in column for all rows in which i am storing multiplication result.

---------- Post updated at 05:00 AM ---------- Previous update was at 04:57 AM ----------

Hi Rudic,
can you please explain the code as what variable is pointing towards which file

Code:
awk 'NR==FNR {EXR[$1 $2] = $3; next} $1 in EXR {$4 = $3 * EXR[$1]} 1' OFS="\t" file2 file1
