Source System Assignment in Update rules

Question

Hello Friends,
Good Day....
I need to extract both transaction data and master data from four different source systems and the data is also different from one soure system to another system.
In BW iam using same infoobjects and the transfer rules,update rules and the datatargets are different. so how can i differentiate data from one system to another system with the same info objects.
<i>where can i do the code can we do that in update routines?
or do we need to do compounding?</i>
sorry friends if i am asking an easy question got confused here....please let me know if any solution.
Regards,
Ala.

Ala,
You could use the client number as a key field / dimension to uniquely identify the records , als you can look out for this info Object called LOGSYS whish if present will get updated by the logical system name or have an infoobject for the same and since your transfer rules will be different for each , have the IOBJ populated by a constant depending on the client and then update the data to the data targets , that should solve your problem.
Hope it helps..
