PCK :: Configuration Example: Message Exchange

Question

Hello experts,
I has a problem with the configuration example from the SAP help to the partner Connectivity Kit.
http://help.sap.com/saphelp_nw04/helpdata/en/8b/895e407aa4c44ce10000000a1550b0/frameset.htm
I have built up everything like in the description - two PCK (party_A and party_B) and XI (party_XI).
In message monitor of the first PCK (party A) stands that a message is explained successfully and second with error.
Status: waiting.
Details -
audit log:
Success Delivering to channel: message_an_xi
Error Exception caught by adapter framework: String index out of range: 0
Error Delivery of the message to the application using connection AFW failed, due to: String index out of range:0.
Message Data:
Error Category XI_J2EE_ADAPTER_ENGINE
Error Code GENERAL_ERROR
Wo und wie muss ich Fehler beseitigen?
Has already explained jemang this example?
Is it executable?
Thank's.
Regards,
Alex

Hi Zoran
While using BPM as well you will need to have communication channels.
BPM - > BAPI request.
BAPI response -> BPM
both sender and receiver channels are required for you.
1.Demand for a material is send via HTTP to XI
2.XI does a material availability check to the SAP system
3.A material reservation has to be done if there are any materials available in the stock (inventory) to the SAP system
4.If there is no material available a purchase order to a supplier (no SAP) has to be done via FTP
5.Parallel to the purchase order a purchase order confirmation is send to the the SAP system.
6.The supplier sends a purchase order confirmation to XI
7.The XI sends a purchase order confirmation to the SAP system
If i understood your requirement correctly and you want to use BPM. You need to do following in BPM
Receivestep1(receive HTTP post) -> transform1(mapping to BAPI request) ->send step1(Send BAPI request to SAP) -> Receivestep2 (Receive BAPI response from SAP) -> Transform2 (Map BAPI response to File)-> send2(File post to non SAP supplier)-> Receive3(receive purchase order confirmation)-> transform3(map to SAP purchase order confirmation)-> send3(Purchase order confirmation to sap)
You need no of channels
1.Receive 1 - (HTTP)
2.Send1/Receive2 - (RFC)
3.Send2 - (FTP)
4. Receive3( HTTP or FTP)
5. For purchase order confirmation.
