Logical System already use in BPM

Hi
We have created two BPMs and one of them the Logical system is configured to 0071ME36. For the second BPM we tried to use the same logical system but we get an error in the XI "Logical System 0071ME36 is already use in the BPM_6547_.
That`s means we must use diferent logical system name for each BPM we created?
Thanks in advanced.

Hi Ger,
>That`s means we must use diferent logical system name for each BPM we created?
Yes, u r right.
One (dirty) trick: Route the message per HTTP adapter back to XI and route incoming message without mapping 2 IDoc adapter. Use only dummy datatyepes, messagetypes, interfaces. There not prooved during runtime.

Logical system already exists in communication component | Sys_R

Hi
What should be done if there are 2 diff systems with the same logical system name. Since the technical systems are different, i am able to create different business systems for it. But it gives errors during ID configuration..
Regards
Monica

Hi
-->Whether the LOGICAL SYSTEMS are assigned to the Same client?It should be for different clients and one LS can assign to 1 existing client.
-->U are creating 2 different TS as WEB AS ABAP so in that you will maintain the details of 2 different systems.
-->finally creating the 2 different BS's in that maintain your LS and for each BS we need to assign the TS name and click finish.(NOTE:While assigning the TS to BS pls observe)
Thanks.

Why do we create logical systems in ALE?

Hi All,
i got this question in interview.
Why do we create logical systems in ALE?
Thanks & Regards
suresh

Hi
In addition to above .
A logical system is used to identify an individual client in a system, for ALE communication between SAP systems. That's why you see a field for 'logical system' in the client master data in SCC4 (table T000).

Re: Assign Logical System to Client

Hi Guys,
Currently our BI client 100 is connected to ECC client 140. Now I want to connect BI client 100 to e-recruiting client 180.
How to do this? How to assign same client to different logical systems?
Regards,
Anand

first i created logical sytem for erecruiting.
for BI the logical system already defined as it is already conected to SAP ecc.
Second step using tcode SCC4, now how to assign the logical system of e recruiting to BI client 100.
Already BI client 100 is assigned to SAP ecc logical system.
Its not allowing me to define another logical system for same client.
Am i doing the right step?

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!!

Juan

Assign a Logical System Name of a production client

Hi everybody,
We have an ERP system (now upgraded to ECC 6.0) that is in productive use since 7 years. Until now, no Logical System Name have been assigned to the production client - the field in transaction SCC4 is empty/blank.
Now we plan to implement a BW, so a test and a productive BW systems have been installed. According to the attached file and content of note 184447 we choose to use "Option 1: Uniform Logical System names clients by system type" for naming convention for LSN's.
All the systems/clients (BW test and productive, ERP test only) now are assigned with corresponding LSN's, except the production ERP client. It is still without LSN and the client is not defined as Source System for productive BW system.
So, my question is:
Should I expect any problems if the LSN of the production client is set up now, after long time, effective productive use?
I would mention that this is infact initial setup, not a change of LSN. Therefore transaction BDLS is not relevant, I think.
Thanks in advance

Hi DB49,
I already did an initial setup of LSN in the test ERP client (that client is copy of the productive ERP client, i.e. the LSN has not been set). And everything seems to be OK.
But the documentation says that ".... In a production system, the logical system must not be changed ...".
"Changed" is not "ïnitial setup" of course, so there will not be any problems I hope, but ...
SCC4 --> LSN field --> F1 -->
"System in which applications run integrated on a shared data basis.
The distribution of data between systems requires that each system in the network has a unique identification. The logical system is used for this purpose.
In the SAP System the client corresponds to a logical system. You can assign a logical system to a client in the client maintenance (choose Goto -> Detail).
The logical system is relevant in the following SAP areas:
ALE general: two or more logical systems communicate with one another.
ALE - ALE business processes (for example, cost center accounting): definition of a system where a specific application runs. Changes to master data can only be made in this system, for example.
Workflow objects: the logical system in which the object is located is always included in an object's key.
When maintaining the logical system, note the following:
The logical system must be unique company-wide. It must not be used by any other system in the ALE integrated group. In a production system, the logical system must not be changed. If the logical system of a document reference is not set to initial and does not match your own, the system assumes the document is located in a different system."

BD54 not allowing to delete logical system

Hi,
We did system refersh from Prod to Quality and further we found that while starting BDLS it was not allowing to do so. We got message like <Target> logical system already existing . Further checks revealed that in BD54 that our quality system's logical client entry was already there which would normally come after running BDLS post DB refresh activity for System refresh). Because of this issue we are unable to dlete the quality entry in BD54 and to further start our BDLS acitivty.
Please to confirm us as we are stuck.
Thanks & Regards,
Ashish Robinson
SAP BASIS Support

Hi ,
Thanks all. I resolved my issue.
Solution:
1) Removed quality system RFC "STQCLNT002" from SM59 just to b sure nothing was blocking
2) Also entry of STQCLNT002 needs to be removed from BD97.
3) Further if you try to use ENTER when you try to delete entry inBD54 of quality it won't allow ,how many time you may try pressing enter to get away with the warning message. So solution here is to further double clieck on that warning message (in BD54) and see where its blocking . It will show you some method where its blocking .
4) To locate the method use txn BD64 and scan through the entires to get to the affected link (here it was STQCLNT002).
5) Be careful, do not delete the entry of STQCLNT002 itseld but actually the corresponding leaves of the methos needs only to be removed to over come the blocking in BD54 (where we wanted to remove the entry of STQCLNT002).
6) Now goto BD54 and and you can easily remove entry of STQCLNT002.
7)Now BDLS would easily start.

Ashish Robinson
Please grant me point if you find the answer useful. It surely did work for me absolutely fine.

Party/Receiver determination/agreement with logical system

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:

Client: 200
WE20: Partner Type LS
...Partner no.: XI_ABC
...Parter type: LS
...Inbound message type: ORDERS
SLD - Technical system:

Name: XI_ABC on xy01sys01cs
...Installed products: SAP R/3 ENTERPRISE, 47X200
...Business systems: XI_ABC
SLD - Business system:
Business system type: Third-Party
Name: XI_ABC
...Related integration server: XD1
Integration Directory:
Scenario: CSC_ABC_ORDER
...Party: PP_ABC_SYSTEM
......Business service: BS_All_Data
......Communication channel: CC_S_File_ABC_Order
......Adapter type: File
...Party: PP_SAPSYS_ABC
......Business system: XI_ABC
......Adapter-specific identifiers: Logical system XI_ABC
......Communication channel: CC_R_IDoc_To_SAP
......Adapter type: IDoc
......RFC destination: D01_200
......Port: SAPD01
......NO Apply Control Record Values from Payload
......NO Identifiers
...Service without Party:
......Business system: XI_ABC
......Adapter-specific identifiers: Logical system XI_ABC
...Receiver Agreement
......Sender party: PP_ABC_SYSTEM
......Service: BS_All_Data
......Receiver: PP_SAPSYS_ABC
......Service: XI_ABC
......Interface: ORDERS.ORDERS05
......Receiver communication channel: CC_R_IDoc_To_SAP
......Sender service constant: XI_ABC
......Receiver party constant: <space>
Once again, thanks for your input.

Change Logical System BW

Hi all,
our basis team changed the logical system name of our BW-Development system (no system copie!!!) becaues the name wasn`t corresponding to the defined naming conventions...
Now when using RSA1 we receive the message "Logical system name has been changed for this system" ok thats clear.
So my question: can I change it back in table T000 and everything is ok again? `
What do I have to consider if I change the logical system name of a already existing and used BW-system or is this not possible?
Many thanks in advance
jb

Hi,
'can I change it back in table T000 and everything is ok again? `
You can chage it back and every thing works properly.
To change the logical system anme USE TCODE: BDLS

Difference between the Logical System n Client

Hi Guys,
i need a some information plz help me.
what r the differences between the logical system n the client.
plz give me the detail explanation
appreciated with points
regards
kk

Hi there,
'logical system' is used to identify an individual client in a system, for ALE
communication between SAP systems. That's why you see a field for 'logical
system' in the client master data in SCC4 (table T000).
Client can be defined as commercial, organizational, and technical terms, a self-contained unit in an SAP system with separate master records and its own set of tables.
Hope it helps

Idoc Acknowledgements - Logical System Name

All,
Stuck with a few issues with Idoc Acknowledgments which I hope SDN can help me with. For ease of understanding the problem, am splitting this into 2 Scenarios ,
Scenario 1
SAP R3 (Idoc ) - XI - File ( Business Service)
R3 Triggers Idoc to XI and XI sends this as a File to the target Application. AleAdudits can be sent back to the R3 system as shown in <a href="/people/saravanakumar.kuppusamy2/blog/2005/01/20/configuration-tips-for-a-business-serviceintegration-process-to-send-back-ale-audit-idoc">this</a> blog by Saravana by adding the Logical System Name to the Business Service.
Issue :
R3 has configured Partner Profile with respect to XI and this cannot be changed. To send the Idoc Ack's back to R3 we need to add the Corresponding Logical System Name to the Business Service.
The problem is - what if the Idoc is to be sent to 2 Different Business Service / Systems. The R3 expects an Acknowledgment with XI as the sender partner but we cannot share the same logical system across different Business Systems / services . The easiest solution seems to be to create different partner profiles in R3, one for each Business System / Service. But this is not possible currently.
Scenario 2: 
R3 - XI - BPM - Target
Idoc triggered from R3, are sent to a BPM and then from the BPM to a file. Everything works fine.
But, the problem lies that when the Ack needs to be sent back to R3, The ack errors out because no Logical System Name is associated with the BPM.
We do not want to add another logical system name to the BPM and thereby create another partner profile and the problem is similar to Scenario 1.
Solutions Explored
1. In the ACK_IDOCAdapter , I tried to select option Take Sender From Payload and Take Receiver from Payload.
But this does not seem to help. I can see the trace in MONI saying the ACK_IDOC adapter is choosen to send the ack back to R3 , but it does not take the Partner Names from the payload of the AleAdudit and errors out with error Unable to convert..
2. As this AleAduit is sent from XI back to R3 and is not a R3 (AleAduit) - XI - R3 (aleaduit) case, adding a entry as shown in Section 6 in
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/903a0abc-e56e-2910-51a8-9dc616df56eb">this</a> document will not help.
Has anyone tried something of this sort. Any known solutions?
I hope the description of the problem made sense, if no, do let me know.
Regards
Bhavesh

Bhavesh,
Your problem as i understand -> The problem is - what if the Idoc is to be sent to 2 Different Business Service / Systems. The R3 expects an Acknowledgment with XI as the sender partner but we cannot share the same logical system across different Business Systems / services . The easiest solution seems to be to create different partner profiles in R3, one for each Business System / Service. But this is not possible currently.

If the IDOC is sent to 2 different business services/systems/Integration Processes, then it is very logical that an ALEAUDIT be sent for each of these business systems/services. Ideally, you SHOULD NOT look at sending a common ALEAUDIT for different recievers in XI, the reason being, failures could happen only for one receiver and NOT for others. Failure could be in the mapping/content conversion. I am assuming here that you are configuring XI to send back "ALEAUDITs" only for System Error Acks(hoping it is possible, since i see 3 XXXs in the IDXNOALE table).
So, it is logical that you configure a different LS in R/3 for each reciever system/service/IP, all these LS's will have one entry for ALEAUDIT in the Inbound params entered in WE20.
If your intention is to send ALEAUDITs back only in case of errors, it makes sense to create an entry for each receiver in R/3. If not, then it is a limitation.

Logical system value in a BAPI

i am using a BAPI, its asking for logical system . How do i know that value ?

Logical system- 'logical system' is used to identify an individual client in a system, for ALE
communication between SAP systems. That's why you see a field for 'logical
system' in the client master data in SCC4 (table T000). You use logical systems
in ALE config - this should be documented further in the IMG guide, or SALE and
BALE transactions.
Check the link
http://www.sap-img.com/bc059.htm
please use Function Modules for this task:
CALL FUNCTION 'OWN_LOGICAL_SYSTEM_GET'...
You can also check the table -
The field is T000-LOGSYS. (Logical System)
