Submit Pip 5C1 to Trading Networks

I’m submitting a 5C1 Pip to TN, the Product Provider Conversation is initiated correctly, but two Demand Creator conversations a initiated. The Demand Creator and Product Provider roles are defined correctly. I’m using the same TN instance to process both documents. I changed the Product Provider 5C1 document root tag so it wouldn’t clash with the Demand Creator root tag.
The Product Provider Document Type root tag is internalPip5C1 and the Demand Creator Root Tag is Pip5C1ProductListNotification.
The Pip that I’m submitting to TN is the internalPip5C1.

Has anyone ever submitted a Pip to be processed in the same instance of TN. Unfortunately we only have one instance available for testing.

     Thanks, Fernando
