Using, a BPEL process polling an AQ for EDI-XML input (which was generated by Oracle B2B) throws the following error:


Error while trying to prepare and execute an API.
An error occurred while preparing and executing the APPS.XX_BPEL_WRITEEDIDATA2ORACLESER.OE_ORDER_PUB$PROCESS_ORDER API.
Caused by: ORA-06531: Reference to uninitialized collection
Check to ensure that the API is defined in the database and that the parameters match the signature of the API. Contact oracle support if error is not fixable.



 Seen in the case where:

    1. Input file is an EDI 850 document.  This input file is placed in a directory (in the machine where Oracle B2B is installed) polled by B2B.  In the B2B system the trading partner ACME (Remote) and GlobalChips (host) are set up using the File 1.0 protocol.  The necessary setup, such as defining the Business Action, Trading Partners, Document Definition, Creating / Deploying the Agreement, and Deployment are done in B2B.


    1. The Oracle B2B generates the EDI-XML using EDI adapter and puts in the Advanced Queue which is part of the B2B schema configured during the installation and configuration of Oracle Integration B2B.


    1. The BPEL process (EDI850InboundService.bpel) dequeues the document from the AQ using the AQ adapter with Consumer name (Document Routing as set up in B2B) QueueName=IP_IN_QUEUE.


  1. The BPEL Process EDI850InboundService.bpel then invokes the Oracle Apps adapter to create a sales order in Oracle Apps.
