Something like this?

Code:
awk -v s='^PO_Number=' '
  NR==FNR {
    A[$1]
    next
  }
  {
    for(i=1; i<=NF; i++)
      if (sub(s,x,$i))
        if ($i in A)
          C[$i]++
  } 

  END {
    for(i in C) print i " --> " C[i]
  }
' po_numbers Test.log  > list3

or with some shell-fu:
Code:
grep -of <(sed 's/^/PO_Number=/' po_numbers) Test.log |
sort -u |
uniq -c |
sed 's/^ *\([0-9]*\) PO_Number=\(.*\)/\2 --> \1/' > list3

RBASH(1)						      General Commands Manual							  RBASH(1)

NAME

       rbash - restricted bash, see bash(1)

RESTRICTED SHELL

       If  bash  is  started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted.  A restricted shell is
       used to set up an environment more controlled than the standard shell.  It behaves identically to bash with the exception that the  follow-
       ing are disallowed or not performed:

       o      changing directories with cd

       o      setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV

       o      specifying command names containing /

       o      specifying a file name containing a / as an argument to the .  builtin command

       o      specifying a filename containing a slash as an argument to the -p option to the hash builtin command

       o      importing function definitions from the shell environment at startup

       o      parsing the value of SHELLOPTS from the shell environment at startup

       o      redirecting output using the >, >|, <>, >&, &>, and >> redirection operators

       o      using the exec builtin command to replace the shell with another command

       o      adding or deleting builtin commands with the -f and -d options to the enable builtin command

       o      using the enable builtin command to enable disabled shell builtins

       o      specifying the -p option to the command builtin command

       o      turning off restricted mode with set +r or set +o restricted.

       These restrictions are enforced after any startup files are read.

       When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
