Idoc to File. Partner type as 'KU' and 'LI'.. Acheivable w/o using Party's?

Question

Hi all,
Idoc to File scenario.
I have the receiver partner type as 'KU' and sender partner type as 'LI'.
I want to create the scenario without using party for these partner Types.
Is it possible for me to create the B2B scenario without using party's?
Is it mandatory that we need to use partys and Identifiers for these kind of scenarios?
Kindly let me know if anyone has idea on this.
Thanks

Hi Seema,
I appreciate that you chose to go with the parties
That should be called a good design decision.......
Now answering your query regarding the party identifiers
Idoc to File :
<SNDPOR>SAPDL1</SNDPOR>
<SNDPRT>LI</SNDPRT>
<SNDPRN>90000</SNDPRN>
<RCVPOR>SAPXI</RCVPOR>
<RCVPRT>KU</RCVPRT>
<RCVPFC>SP</RCVPFC>
<RCVPRN>36</RCVPRN>
For Sender Party (say party INTERNAL)
Agency : LD1_001
Scheme: ALE#LI
Name: 90000  (vendor number set in WE20 in the R/3)
For Receiver Party (say party EXTERNAL)
Agency: LDI_001 (SID_<client> BS as defined in SLD)
Scheme: ALE#KU#AG  (AG for partner function SP)
Name: 36  (customer number set in WE20 in the R/3
This will resolve the IDoc header data into the following XI SOAP header information:
Sender Party - INTERNAL
Sender Service - LD1_001 (say this is the business system defined for logical system SAPLD1
Receiver Party - EXTERNAL.
Though, you can determine the receiver party alongwith the Receiver Service later at RCV DETERMINATION step, as I have said earlier.
Yes, for outbound you have to maintain the identifiers for Sender Party type LI, but you can still skip the Receiver KU type and update the SOAP header at RCV DET step.
File to Idoc:
<SNDPOR>SAPXI</SNDPOR>
<SNDPRT>KU</SNDPRT>
<SNDPRN>36</SNDPRN>
<SNDPFC>SP</SNDPFC>
<RCVPOR>SAPDL1</RCVPOR>
<RCVPRT>LS</RCVPRT>
<RCVPRN>MAINSAP</RCVPRN>
For Sender Party (say party INTERNAL)
Agency: LD1_001 (SID_<client>)
Scheme: ALE#KU#AG
Name: 36
For Receiver Party (say party EXTERNAL)
Because the RCVPRT value is LS , no need to set the Receiver Party for that.
But if you want to have some Receiver Party value for the same you can use Header Mapping in receiver agreement.
Mandatory Setup in Receiver IDoc Adapter:
Set the indicator -  Apply Control Record Values from Payload
Remember to set the Identifiers in the Identifiers Tab in Idoc channel.
Sender:
Agency : LD1_001       Scehma : ALE#KU#AG
Receiver:
Agency: LD1_001        Schema : ALE#LS
I am not sure why this ALE#LS entry is required, but according to my experience if we don't have that entry, the Idoc Adapter throws error while converting the Receiver Party (considering you use party in the ID configuration for both Sender and Receiver).
Yes you are right, you can hard code the SNDPRN, RCVPRN values in the mapping and can take the values from payload...........for that set the following Indicators in Idoc channel:
Take Sender from Payload
Take Receiver from Payload
Let me know if you have any concerns or any additional observation you make while configuring the scenarios. Thanks.
