Party/Receiver determination/agreement with logical system

Question

Hi all
I have gone thru various messages in the forum dealing more or less with the issue, but haven't really found an answer to my problem yet.
XML orders from a Web shop are sent to XI, which I am mapping to an IDoc of type ORDERS.ORDERS05 to be sent to the SAP R/3 backend system. The partner profile in the backend system is defined as a logical system because (a) even though the Web shop is for a closed user group of known customers, I could not possible create a partner profile of type KU for every of them, and (b) I need to do some special stuff for IDocs of this order process which is triggered by a separate process code.
My plan in XI configuration was to create a new scenario and setting up either two parties or one party and a service without party (with a business service). I have tried both ways, but I am not getting it to work. The main reason for that is because of "Unable to convert sender service xxx to an ALE logical system". The "standard logical system" is used in another scenario already, and because of the special processing in the backend, I would like to keep it separate by a logical system defined for this process only anyway.
Posts with party definitions and logical system problems exist already, but I haven't really found a applicable answer. Can something be done in the header mapping (which I am not so familiar with yet) to get one or the other way to work, or is there another "good" way completely to handle this?
I am a little bit lost right now, and would appreciate your feedback. Thanks,
Daniel

Hi Michal
Thanks for your feedback. I have implemented the scenario anew based on your input, and other information that I've found. I've got a working solution after playing around with the settings for a while, and is as following now:
R/3:
System id: D01
Client: 200
WE20: Partner Type LS
...Partner no.: XI_ABC
...Parter type: LS
...Inbound message type: ORDERS
SLD - Technical system:
Technical system type: Third-Party
Name: XI_ABC on xy01sys01cs
...Installed products: SAP R/3 ENTERPRISE, 47X200
...Business systems: XI_ABC
SLD - Business system:

Once again, thanks for your input.
