Send errors out

Hi,
I am trying to send 3A4V02.02. Trading netwoks is able to recognise Intenal Po Request doc type but it doesn’t recognise PIP3A4V02.02. It shows dotype as unknown. I have PIP3A4V02.02 installed and TPA set for the same. I am kind of stuck. How should I go about.

Send errors out with the following message,

Resoloved by installing PIP0A1 process model.
Thanks,
