2457375 - SXMB_MONI: document number of cXML messages not shown

You use the Ariba Network Integration for SAP Business Suite add-on (a.k.a. ARBERP or BSAO) and cXML messages for the communication between Ariba and the ERP system. When you check the cXML messages in SXMB_MONI or SXI_MONITOR, you notice the the document number is not filled in the columns 'Queue/Sequence' and 'Queue Name'. This is true for both inbound and outbound messages.
You expect these columns to be filled, because they are filled in case of other message types e.g. PurchaseOrderERPRequest_Out
