ORDERS05 enhanced with WEMPF and ABLAD

Question

Hi
I need to enhance ORDERS05 Idoc used for Purchase Orders with Reciepient EKKN -WEMPF and Unloading Point EKKN-ABLAD.
In my case Reciepient and Unloading point are both text fields used in PO in order to indicate to suuplier where and to whom goods needs to be delivered.
Please tell me what options do I have: Extention/User Exit/or??????
I went through documentation for ORDERS05 and I can not find standard segment/field that would correspond to my need.
Thanks for hints

Hello,
Yes we work with enhanced interface determination.
There are two steps
First, maintain Database Table in SAP XI. Which contains several keys like Sender, Receiver, Process and then according to that key combination we perform a JCO call and fetch the values which gives us the correct receiver and interface.
Create a Data Type which will be having Two elements Service And Interface.
Now careate a message type and message interface for this data type. This will be your receiver.
Then use source payload and perform a message mapping between Sender Payload & this Message Mapping.
Use UDF and make a JCO call and fetch table entries for service and interface.
Then in Directory perform extended determination and use this mapping into it. The result will be Service & Interface.
