Hello Sriram,
Thank you for your help 
Regarding the SAP NW Process Integration (SAP PI)... can you tell me what is the relationship between this product and the SAP Process Orchestration (SAP PO) product. I don´t understand if the SAP PO is or not the continuation of SAP PI, I mean, if it is the latest version of SAP PI product.
Can you clarify me please?
Thank you,
samid raif
