You can do that by putting the entire awk script in a command substitution construct:

Code:
Rej=$(
  awk -v FS='|' -v OFS='|' '
  BEGIN {
     ........
  }
    ....
  }
  
  END {
    print Rej
  }
  }' f=$DMU_File $Predum_file > Validation.err
)


But the awk script should print to stderr instead of stdout:

Code:
........
        {    print "RECORD "NR": Mismatch Fould in Field:"fld_arr[i] " Actual value ("F[i]")...But Expected value ("k[i]")\n" > "/dev/stderr"[/COLOR]
             if (a != NR)
               {
                        Rej++;
                        a=NR;
                }
}
}
}
  END {
    print Rej
  }
}' f=$DMU_File $Predum_file 2> Validation.err
)

----
An alternative is to use

Code:
print "RECORD "NR": Mismatch Fould in Field:"fld_arr[i] " Actual value ("F[i]")...But Expected value ("k[i]")\n" [COLOR="Red"]>"validation.err"

and
Code:
}' f=$DMU_File $Predum_file


----
But perhaps if you post input and output samples, we could advise on how the script might be improved...
