Confusion on Logical System (Idoc)

Hi Guru's
Please help me out
I have two SAP System : ex SAP A client 100 and SAP B clint 200.
My Sender system is SAP A(100) and Reciver SAP B(200)
I have to do ALE configuration. I got stuck in SALE Transaction is Client assignment.
As i have to define Logical system for Both SAP A and SAP B.
But in Assignement part what should i do
Should i assign Logical system of SAP A( 100) to client 100 or 200?and what should i do for Logical System of B?
I hope i need to assign the Logical system of both system in SAP A to some client.
Regards
RJ

Hi,
Find the steps below.
1.Go to SALE transaction
2.Define Logical system (Use only the existing Logical systems).
3.Assign client to the logical system. (Never change the existing assignments).
4.Define target systems for RFC calls. (We can do this using SM59 also).(Always maintain same names and descriptions for RFC destinations like Logical system.)
Example:
       Logical system in 100: LS_100
       RFC destination in client 200 should also be LS_100
       Logical system in 200: LS_200
       RFC destination in CLIENT 100 should also be LS_200
       For a better practice always maintain both RFC destinations in both sending and receiving systems.
Hope this helps.
Regards,
SuryaD.

Confusion in Logical System, port & RFC Destination

hi,
I have still few doubts regarding Logical System, port and RFC destication
My SAP ECC6.0 and XI configuration is:
For ECC 6.0 : Logical system name : T03CLNT400
Client : 400
RFC Dest : XIDEST
Port : XIPORT
For XI 3.0 : Logical System name : WXI
client : 400
RFC Dest : ECCDEST
Port : SAPEC3
now my confusion is, in t-code WE19, when sending IDOC to XI (idoc - file scenario), which entry i've to use in prot and Partner No in Receiver side and which port and partner no i've to use in Sender Side.
also in XI side when creating Technical sys for web as ABAP which logical system name i've to use and in File to Idoc Scenario which logical system i've to use as sender business system (third party file business system)
If possible please give me detail idea to clarify my cofusion.
thanks

If you are sending from R3 then give the sender details as R3 and the receiver side as XI where you have created the port from R3 to XI etc.

What is logical system in ALE

Dear all
I still confuse with Logical System in ALE where we already have Client.
And I see that relationship between Client and Logical System is 1:1
So why we need Logical System instead just use Client ?
Regards,
Halomoan

I think this is what you want to read:
A logical system is an unique identifier of a system/client combination.
That is why SAP recommends to use the notation <SID>CLNT<CLT> to set the logical system. For example, assume you have client 400 for system QA1 and you have client 400 for system DV1. Then the logical system name would be:
for QA1/400: QA1CLNT400
for DV1/400: DV1CLNT400
The logical system is used in the IDOCS that you transmit from one system to the other. So with this, you know the source system of the IDOC, and this tells you where the business document was created.
Using only the client as identifier is not enough, because you can have the same client number in several systems.
Nevertheless, you should read the documentation!!

Logical System in IDOC-XI scenario

Hi,
I need help to understand few things in IDOC-XI scenario, could any one help me in this regard.
we use Adapter specific identifiers to map services, we have following type of identifiers 1) Sys.ID & Client No. 2) Logical System.
my questions are
a) Are we use Logical System in B to B scenario ?
b) Are we use LS in reference to the SAP system or Non SAP system ? if a non SAP system....how a non SAP system send an IDOC and why a non SAP system receive an IDOC ( conversion is possible in XI ) ?
Thanks and Regards
Mahesh.

Hay Kumar,
Logical systems can also be used for SAp sytems wich are not installed yet as a virtuall placeholder.
a) yes. if on of your business is a non sap system or a propritery system that you developed yuo'll ue LS.
b) non SAP system can send and recieve IDOCs. so it's possiable to get an IDOC from a system and turn it into an RFC for SAP or get an IDOC from an SAP system and then turn it into something else for another system.
Have a Good One,
Uri Lifshitz.

Logical System in file 2 idoc

Hi
I am developing an scenario of file to idoc.
My problem is, when it is generating the idoc in target system, the Parner Number in control record is filling with the logical system name given when creating the business system.
I tried changing the logical system name with actual partner number which I want but giving an error ' The selected integration server already has a business system with logical name "pidclnt001". Select a different integration server or change the logical name. '
Can anybody advice me, is it not possible to create two scenarios to send same Idoc to same system ?
Regards,
Shylesh

Hi Shylesh !
You need to enable the header mapping option in your receiver agreement to overwrite the Logical System name that is sent to the R/3 destination system...which now is the Logical System name linked to your sender system (info is in SLD if is a business SYSTEM or in the Adapter Specific identifier attributes if it is a business SERVICE)
You cannot have more than 1 business service/system with the same Logical System name...but you can overwrite the sender logical system name that arrives to the destination R/3 system using the header mapping section of the receiver agreement as noted above.

Matias.

IDOC sender: Error in Logical system name?

Hi,
In my current project, the IDOC sender system logical name is P2PCLNT100 but the SLD system name is P2P.
Its an IDOC to proxy scenario. At the receiver system side, the schemeAgencyID is getting populated at P2P and not P2PCLNT100, due to which there is an error on the receiver's side.
Following is already checked:
1. SLD has maintained the proper logical system name for the P2P system
2. The IDOC xml on the XI system has the sender port properly populated as P2PCLNT100
3. I have also debugged the program on the receiver side and fails at a point where it checks the logical system name from the database BBP_BACKEND_DEST.
On the receiver system, the followed error is shown as follows:
- <STANDARD>
<CONTROLLER />
<FAULT_TEXT>An error occured within an XI interface: SLD system P2P is not known Programm: SAPLBBP_BD_MAPPING_SAPXML1; Include: LBBP_BD_MAPPING_SAPXML1F1Y; Line: 96</FAULT_TEXT>
<FAULT_URL />
<FAULT_DETAIL />
</STANDARD>
Thanks in advance for the useful answers.

Hi,
1. R/3 system's logical system name and SLD business system's logical system name has the same.
Is there a need to have the business system name in SLD to have the same name as R/3 system logical name?? As far as my knowledge goes, business system and logical system need not have the same name. Correct me if in the case IDOC sender scenario is different..
2. SLDCHECK shows following message:
Summary: Connection to SLD does not work
The issue still persists. Will SLDCHECK correct solve the issue?

XI 3 File to IDoc scenario - Still referencing Old Logical system

Hi
Dont know if you can help. I have a file to idoc scenario using XI 3 to R/3 4.6c system.
I had the interface working from a third party system XMLHUB to SAP R/3. The Logical system name for the XMLHUB was XMLHUB01 in the SLD which I have set up as a partner profile in R/3. I have recently changed the logical system name to XMLHUBDEV01 in the SLD and created that logical system in R/3 and changed the partner profile to XMLHUBDEV01.
Unfortunately in the sender information of the IDoc the partner number is still XMLHUB01 and not XMLHUBDEV01. I don't understand where this partner is sent from to get into the control record of the IDoc.
I have cleared the SLD cache in both the Repository and the directory. Is there somewhere else I should be looking? Any help would be appreciated.
Regards
Daniel

Integration server as logical system in IDoc to file scenario

Hi,
Will we configure integration server as logical system in IDoc to file scenario or the RFC destination related to the port will be suffice?
For which logical system will the outbound partner profile configured?
Regards,
Gajendra.

Hello,
I feel that the RFC destination linked to the port is the key here.
Because the scenario (IDoc to File) works in both the cases:
Case 1: Used the logical system as Integration server
Case 2: Used the logical system related to the file (third party) in the SLD.
In both the above cases the RFC destination points to the integration server.
Is this the case that in the XI scenarios (where IDoc are sent) the logical system name in the partner profile is just dummy and has not much significance??
It is the port that matters and once the Idoc reaches XI the routing takes place based on the configuration in ID.
Thanks.

Gajendra.

Logical systems in ALE iDoc

Hi,
For exchanging data between two systems(not between two clients of the same system) using ALE iDoc , logical systems should be maintained in both the systems?
For eg: there are two systems, system A and system B.
i have maintained the logical systems as SYSA (for system A) and SYSB ( for system B) in the system A using the transaction 'SALE'. Should this need to be maintained in system B also?
Thanks & Regards,
Soumya.

Hi,
In both the systems you have to Define the Logical systems,
but in you assign only one to the client,
i.e. in system A you assign the Logical Sytem of of A to the Client in SALE
transaction the same goes for B.
and you don't need to create a distribution model for both the systems,
you can create it in one system and send it to the other system.

RPM_FIN02 - Receiver of IDoc is its own logical system

For one particular portfolio item, I run the RPM program RPM_FIN02.
This results in an IDoc creation.
Next, I checked the status of the IDoc (RPM > Base System Interfaces > SAP Financial and Controlling Integration > Data Distribution From SAP FI-CO to SAP xRPM > Check Inbound Processing).
This shows the status "29 - Receiver of IDoc is its own logical system".
As a result, the Internal Order costs (including the ones posted from cProjects) do not get pulled into RPM Financial Planning.
Please advise.
I do not have the technical understanding of this issue, and would therefore need a little more than the mere technical jargons and terms to be able to resolve this.
Thanks for understanding.

Hi,
Very briefly,
-Assuming your RPM system is independent of your ECC box. But RFC connected.
-RPM_FIN02 is for pulling in financial data onto RPM item from (object linked) Internal Order(IO)/PS Project(PSP).
-RPM_FIN02 do not recognize/goto cProjects for financials.
-cProjects can have its own account assigned IO/PSP
-cProjects Dashboard, (if all is well incl. evaluation) should display costs from assigned IO/PSP
-This cost does not reach RPM item
-Source of cProjects- if it is created within cProjects or from RPM Item, does not matter.
thanks,Mathavan

JDBC to Idoc scenario - change of logical system name

Hi,
I have a JDBC to idoc scenario that worked. Now i had to change the logical system name from my sender system from ABC_123 into ABC123 in the SLD (Business System - Integration - Logical System name). I did so and also refreshed my Cache.
Afterwards I started the process, but it failed in the Receiver system. The idoc is correct expect of the partner name. My receiver system expect ABC123 - as I changed in the SLD - but PI send ABC_123.
If io look in SXI_CACHE - Services my Business System still got the "old" name (ABC_123).
Did i miss something resp. how can i load the current configuration from SLD?
Thanks in advance
Michael

Hi Michael,
Again Import the changed logical system in the Integration directory of you PI system.
And check the scenario (Sender Agreement, Receiver agreement ) what system they are reflecting.
If they are showing old system then you have to replace the business system in all the scenario.

IDoc Adapter - Logical System - File to IDOC configuration

I have a scenario reading a File ->XI->IDoc in R/3. I'm looking to have the control record parameter for SNDPRN reflect the Environment dealt with. I unchecked the 'Apply Control Record Values from Payload' & 'Take Sender from Payload' boxes but the problem I'm getting is that the system is reading from the business service (IDoc Adapter - Logical System) and feed it in the Partner Profile in the IDOC. This means that I should all the time redefine 3 this Logical System in config before transporting my scenario from DEV/QA/PRD. Any idea how I can avoid this kind of 'hardcode' ?
Thanks

Hi,
Why u r using three different LS can't u use only one LS and send all the IDOCs to same LS. That will ease ur task.
Do let me know why u r going for three different LS.
In the file r u getting any data which will help u to identify that this file is for which LS. IF that is the scenario then u can use the value mapping and based on the value which is coming in file u can map it to the IDOc filed which u have mentioned and in the configuration it will take the respective configuration.
Thnx

Logical System Name of an Idoc Sender

Hi,
I have seen that For Idoc senders the the Logical System name associated with the sending Client has to be SAP+System Id(For example SAPE05 where System Id = E05).
Is it mandatory? If so how can I have multiple clients in a sender Idoc systems sending data?
Regards.

The logical system nameing convention is:
<System ID>CLNT<Client>.
If your system is ADM, client 070, the name would be:
ADMCLNT070.
