Payroll parallel reconciliation with external non-SAP System

Question

Hi folks,
     Did any one of you work on "payroll parallel reconciliation” project . We have data coming through SAP "payroll" results as well as from an external system. We have some wage types, schemas and some results tables in SAP payroll out put, they also have something like wage types and payroll results in external system. What I’m thinking that we can download the payroll result and write some macros in excel sheet or do Vlookup. Other approach is to upload external system data in to Sap and validate , or check what every condition are there .
What else can we do? Please give your inputs/suggestions.
Thanks

Hi saquib,
1. I suppose, apart from compareison of
   sap figures <-------> external software figures,
   , there is no other motive / purpose.
2. There are 2 important things :
   a) No need to validate thru macro
      or paralllel online comparison.
     (don't go for such approach, as it may
      hinder sap normal business process)
   b) after payroll is processed in both systems,
      only after that,
      comparison should be done.
3. Now the question comes, where should the
   validation be done ?
   a) sap
   b) external software
   c) excel
   d) others.
4. Doing in excel and checking each figure
   can be done, provided we know how to do
   and we are expert at it.
5. Other thing is,
   a) make y table for uploading data of external system
    (simple y table with wage type, amount, period.
  b) make a small z program to upload
    the data, 
    do the comparison, one by one.
  c) if required, the program can list
    out the variances.
6. I personally feel, this shold be the
    best approach.
   (This comparison program can be developed
    in external software also.
   However, to download sap  data
   we once again have to create a small z program.,
  so why not, make one z program, once and for all )
