Integration

Hi,
I am getting the error: B2B-50547 Agreement not found for trading partners: FromTP null, ToTP OracleServices with document type PurchaseOrder-1.0-INBOUND

I am following a the example in a chapter from Oracle SOA Suite 11g R1: A Hands-on tutorial

The idea is to use a local XML file of purchase orders as input to be processed by B2B and sent to the Composite where I process and load it in the database.
Defined in the B2B console the partners, document definition, listening channel as file, and agreement, and B2B adapter in the composite.

On testing I do see in the B2B console the transaction with the correct XML payload but no instances are started in the SOA composite.
The displayed error in B2B console is: B2B-50547 Agreement not found for trading partners: FromTP null, ToTP OracleServices with document type PurchaseOrder-1.0-INBOUND.

It is strange that the from adapter is Null, yet the source file is being processed and actually deleted from the folder fine!?

From B2B console:

I can provide summary of full steps and the log content.

Need to get the test to work to show value of B2B over older technologies. Please help.

Thanks
