Hi,
You are right the TPA will be created when you will build the PIP document, but “nsDecls” vlaue should have the fully qualified PIP document namespace from wmRnPiPs directory on IS.
How have you created the PIP? if its from PIP builder, then it will create PIP documents, TPA, TN Document, nsdecls.
Hope you must be having the proper PIP in receive step of your process model.
