Role of TPA in 601

Hi,

I am going through 6.0.1 documentation from the perspective of promoting TN Rosettanet Conversation scripts to 6.0.1 Process scripts. This is where i came across TPA and I am reading the documentation. But the concept behind TPA, its requirement and its role in Rosettanet or edi is not coming to my mind despite reading the doc. Maybe i need to read it paying more attention. It would be great if i can hear the role of TPA/why TPA? from you.

Thanks in advance
DG
