IDOC to be triggered based on Lookup value

Question

Hi all,
   There is a requirement where in we wil have to trigger IDOCon the receiver  based on certain value which will be coming from RFC lookup during mapping runtime.
So the entire scenario goes like this
If look up result is 1 trigger IDOCX to receiverA,
if look up result is 2 trigger IDOCY to receiverA.(receiver is same for both the cases).
1. I think its not possible by using the combination of multimapping and enhanced interfacedetermiation,because multimapping doesnot support IDOC choosing , as it creates the second IDOC with error .even tough occurances have been changed.
2. To apply condition in the interface determination to select required IDOC receiverinterface. The valueis not coming from source structure but coming from look up.
Please suggest the better solution to acheive it.
Thanks,
Amar.

Answer 1

Hi Amar,
Yes It is Possible.
1.Export the both IDOcs in XSD format and Change the Occurance of like (<xsd:element name="IDOC" minOccurs="0"   maxOccurs="unbounded" type="MessageType.BasicType"/>)
2.Create Two External Definitions(ED_IdocOne & ED_IdocTwo) and Import (Modified) XSD format (No need to Create any Message Type & Service Interface)
3.Message Mapping(MM_MultiMapp), Import the Both External Definitions(ED_IdocOne & ED_IdocTwo), using CREATEIF Node function Complete your Mapping, and under Signature Tab Change the both of External Definitions Occurence like 0......unbound
4. Operational Mapping(OM_MultiMapp),Import the Both Idocs(which is importhe from ECC) and Change the Signatures like 0.......unbound and Import the MultiMapping(MM_MultiMapp).
5. Then Complete Your RFC LookUps.
Configurations
1.Create Business Systems and Communication Channel
2.Create one Sender Agreement
3. Create Two Receiver Agreements
4. Create Interface Determination
5. Create Receiver Determination
but, whether u execute the both IDOcs same time the Monitoring Time(SXMB_MONI) it displays Black Flag but doesn't display the PAYLOAD, then Go ECC and check (TCode   we02)
