Issue with same R/3 system ID - Client in XI landscape

Question

Hi there,
<b>WHAT:</b>
We are experiencing a serious problem in our XI landscape.
The source of the problem is due to different SAP systems within the same landscape which have the same system ID and client nr. Our customer has divided its business into internal companies which use different SAP boxes/instances but share the same XI environment.
<b>HOW:</b>
All systems have been defined in SLD as technical and business systems. This is an example how it looks like in SLD:
DEV on business-system1; client 200
DEV on business-system2; client 200
PRD on business-system5; client 400
PRD on business-system6; client 400
<b>WHEN:</b>
When we try to add a second business system/service (in the integration-builder directory) with the same combination of System ID (i.e. DEV) and  client nr. (e.g. 200), XI does not allow you to activate this second system.
The error message we get; There's already another system configured in the directory with this same combination of system ID + client.
Is this behavior normal? Why is the integration-builder/directory looking at the technical details of the configured systems in SLD?
Is this a feature or a bug?
Please send me any feedback or some clues how to figure out what's going on here, tnx all.
Rob.

Sravya,
Actually that's the situation we have now; we have two different BS (in this case with the same attributes: SYSTEM ID=DEV and CLIENT=200.) installed on top of two different TS's. This configuration is not accepted by the Directory in the configuration builder. As I said before when you try to add the second BS with the same attributes, XI generates an error that does not allow you to activate the change list.
So these two BS's have to be configured in SLD as different BS's, otherwise XI would not be able to correctly do the technical routing.
What I dont understand is why is XI looking at technical data from this systems at configuration time ? As far I know at configuration time XI is only suppose to work with data declared in the business system information and not at technical details like system ID's and client numbers. These kind of information belongs to the SLD layer and not at configuration level.
<i>Please correct me if Im wrong, tnx.</i>
