PI Usage


In our landscape we have SAP ECC,SAP CRM, SAP BW, Redprairie WMS, Hyperion and a set of custom applications. Currently direct communication is happening between these systems.

We are planning to use SAP PI 7.0 as a middleware.

We are planning to shift all the direct communications through PI.

Is this the right way ?? bcoz SAP ECC,SAP CRM, SAP BW can talk directly also.

Is there any guidelines for deciding this ??

Thanks in Advance,
