FDM, How to replace the value of my source file inside BefFileImport

Question

Hi all,
I want to edit some value that will need some validating inside the source file with some condition inside the source file.
I know the easy way is to build the validation inside import script, but the import script usually will run for each row, if I put the logic inside it will make the performance slow, I assume, because every one row, it will open the file.
So I try to do one time conversion, so I choose to put my logic inside BefFileImport VBScript, but after my script run, the value was not change, it still stick with old value.
Need your help for this.
the below example, I want to do
Sub BefFileImport(strLoc, strCat, strPer, strFile)
If InStr(strFile,"test123")>0 Then
Location="C:\Oracle\FDMApp\SampleApp\Inbox\Batches\OpenBatch\"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f1 = fso.OpenTextFile(Location & strFile, 1)
Set str= CreateObject("System.Collections.ArrayList")
Do Until f1.AtEndOfStream
  str.add f1.ReadLine
Loop
Set f1=Nothing
Set f2 = fso.OpenTextFile(Location & strFile, 2)
For Each dataLine In str
  tmp = Split(dataLine,";")
  value = valcheck(str,tmp(14),tmp(13), tmp(6), tmp(1))
  If  entityPartner = "" Then
  f2.WriteLine tmp(0) & ";" & tmp(1) & ";" & tmp(2) & ";" & tmp(3) & ";" & tmp(4) & ";" & tmp(14)
  Else
  f2.WriteLine tmp(0) & ";" & tmp(1) & ";" & tmp(2) & ";" & tmp(3) & ";" & tmp(4) & ";"& value
  End If
Next
Set f2=Nothing
Set str=Nothing
Set fso=Nothing
End If
End Sub
Thanks

Hi
You can achieve this with virtual characteristics option. Code the logic in the customer exit program and it would work.
Thanks & Regards
