Logical System,Business System

Hi Gurus,
What is Logical System? n What is Business System?
Wt is the Difference betweent these two?Can you explain me in detial.
thanks in advacne.

Hi Kumar
Logical System
System in which applications sharing a common data basis run. In SAP terms, a logical system is a client in a database. Messages are exchanged between logical systems.
Systems of the Central User Administration (CUA) are referred to using logical system IDs. In the SAP sense, a logical system is a client. Therefore you must first set up logical system names that you then assign to the clients in the SAP systems.
It is possible that the logical system name already exists because you have already included the system in an ALE distribution. You can then ignore the procedures Define/Set Up Logical System and Assign Logical System to a Client.
Business systems are logical systems that function as senders or receivers within the SAP Exchange Infrastructure. You configure business systems in the SAP System Landscape Directory (SLD). A business system is always associated with a technical system (here: SAP Web AS ABAP system).

Logical Systems in Business Services

Hi
In Business Service creation, for Adapter Specific Identifiers, the parameter for the Logical System. It is only possible to assign one logical system to one Business Service ?.
i.e. to do
MyBusServ1, Z_LS_1
MyBusServ2, Z_LS_1
is not possible ?
When trying to assign Z_LS_1 to MyBusServ2 I get the error that Z_LS_1 is already assigned. Is there a way to circumvent ?, I do not want to create two logical systems in R/3 as the IDOCS types submitted by the Business Services are the same.
Thanks
Damien

Thanks for the replies
Sarvesh - The Business service is the sender of the information \ IDOC. If I remove the Adapter specific config then how will XI know what Logical system to apply to the IDOC ?.
Jaishankar - I am creating two IDOC's in SAP. MATMAS and PORDCR. The input file are coming from two different source systems. lets say sys1 and sys2. Both of thse for clarity are created in my scenario as Business Services. sys 1 creates MATMAS and PORDCR IDOC's int he syatem, sys2 creates PORDCR IDOC's in the system. As sys1 and sys2 are related in that they created the IDOC's as part od the same project then I would like to collect in the same partner profile in SAP e.g. Partner Profile ZPP_IDOC with IDOC types MATMAS PORDCR that serve as input for both systems. Logically I would assume that I can assing the logical system ZPP_IDOC to both the adapter specific parameter in both sys1 and sys2.
Thanks

Logical System Name Not appearing in the Business System

Hi,
Initially we had created a Technical system with Client 700 without a "Logical System Name" in SLD. hence the 'logical system name' in 'business system' was also Blank.
Now, since we are implementing the IDOC to file scenario; we need to maintain the "Logical System Name" in the client and which in turn should reflect in our Business System in SLD.
Though we maintained the Logical System Name in the Technical System --> Client --> Logical System Name; we are unable to see the same(Logical System Name) in Business System ('Integration' tab)
Please also note that Business System is of the ROLE: Integration server.
When we go to business system in SLD ---Integrtaion tab ---Logical System Name -- is still blank.
Can anyone please help us to update the 'Logical system name' in Business System in SLD?
Regards,
Rehan

Hi Sunil,
I followed your link till
Bussiness System -> select your bussiness System -> in Below pane u will find Details of your bussiness system ->amongs the various tabs available select Integration Tab->U will See option for technical system beside that u will see option for change ->click this ->u will be taken to Logical system ->there u define u r logical syatem name and then save the entries.
When I clicked the option chnage ---> "Change Associated Technical System" appeared, It didn't take me to Logical system.
But in turn I clicked hyperlink corresponding to Technical systems, it took me to technical system --> clients tab --I have entered the Logical system name.
When I go back to Business system again its not showing the Logical system name in Integration tab.

rehan

Logical system and business system

Hi experts, please help me with the below questions---
1) What is the diff between logical system and business system?
2)what is the difference between logical system(defined in R/3) and business system (defined in SLD) in idoc to file scenario.
3) Is it require to give the logical system name of the xi server(Which we define in idx1 port) to the 3rd party system(Application system at the FTP side) to carry out file to idoc scerario?

Hi,
Business System :
1. Business systems are logical systems, which function as senders or receivers within XI. Business systems can be SAP systems or third-party systems. Depending on the associated technical system.
2. Business Systems should be mandatory used when dealing with Idoc's and Proxies .
Business Service:
1. Business Service requires manual adding on Inbound and Outbound Interfaces, Business Systems do not.
2. Business Services are maintained across environments and so, their names cannot be changed. Business Systems names can be changed across environments by providing SLD level transport targets.
3.In the Business Services we cannot maintain the Group and Targets in SLD. For Ease in transporting your ID/Configuration objects Groups and Targets are used in SLD for Business Systems.
4.Business Service has no SLD Entries and No Assigned Products and SWCV's

Already used Logical System in Business Service?!

Hi, well i am facing a JMS2IDoc-Scenario.
As sender i configured a Business Service (K15) with the CC_JMS. The receiver is a business system (HRT) with the CC_IDoc.
While i test the scenario i received following error:
"Unable to convert sender service to an ALE logical system"
Thats fine so far, therefore i checked the Adapter-Specific Identifiers and entered the Logical-System name. This is already in use at the business system (HRT) because of some CC for other Scenarios.
Now there is the problem that i can't use this logical system name at K15, no idea why.
Because of not having the technical details of the source-system (JMS) i choose to use business service. Is there another idea?! Party?!
br, Jens

Hi,
The issue is with the fact that this Logical System Name has been assigned to another Business System ( say Buss System X) .And you want to use this same Logical System Name for the sender JMS service( Buss System Y) as well , correct?
Solution is,
In the Receiver Agreement , Select Header Mapping and for the Sender Servicce, select the Correspodning Sender Service ( Sleect Buss System X )to which the Logical System Name is assigned.
Now in the runtime this will be used as the Sender Service from which the Logical System Needs to be taken.

Logical system name in business system (SLD)

Hi,
While creating business system in SLD what should give for the logical system name?
Should the logical system name exists in ABAP stack or the new one?
Thanks.

Hi,
If you are creating the BS for SAP R/3 in SLD means we have to give the LS name which we had in SAP R/3( goto SALE and take the LS from there)
Goto Assign LS-----take the client which you are using for SAP R/3 and take the LS name assigned to that Client

ALE logical systems for business service or process

Hi,
I am trying to send an IDOC into my R/3 system. It is the same IDOC type that I have sucessfully sent out to parties. All the config is in place for communicating with the system, because I have sent others IDOCs in the past. However, they always were sent from another R/3 business system. They processed sucessfully.
I am now trying to sending IDOC's from a BPM,as well as, from a business service. They are under the "With Party" section of the directory. These obviously do not have logical systems, so when I try to send the IDOC I get
"Unable to convert the sender service Purchase_Orders to an ALE logical system", where purchase_Orders being the name of the business serice.
How can I handle this problem?
Should I hard code values somewhere?
Which ones?
I have read the other posts for the error above, but my situation seems to be different.
Help!
Chris

Hi,
To solve your problem, here my solution:
1/ In your Business Process of your ID (configurator), go to menu "Service > Adapter-specific identifier" and in the part "IDoc Adapter", write your Logical System.
2/ Create this Logical System on your target system (R/3).
WARNING: XI allows you to used a Logical System for only one service (Business Process). Thus, if you are several interfaces, you must used different Logical Systems.

Logical system for business service!!!!!!!!!

Hi all,
I send a file from filesystem to XI which inturn converted to IDOC and posted to SAP system. Filesystem i've added as a business system(which has a logical system in R/3).
now i've added the filesystem as a business service(assinged to a party). So if send the file i'm getting the error as "Unable to convert sender service to an ALE logical system".
How can i resolve this problem?
can we assign the business service a logical system name ?(as business system)
What could be the procedure for processing this kind of b2b scenario where we dont have information about systems or sevices in SLD?
Thanks in advance for your replies........

Logical system not updated in the business system adapter specific data par

Hello Guys,
I changed a logical system name in the sld for a business system and that that is not reflected in the Integration directory adapter specific data tab.
I did a cache refresh using :
1) sxi_cache --- Full cache refresh, delta cache refresh
2) Hard cache refresh
3) In ID "Cleared SLD data cahe "
4) Refreshed the exchange profile
But no use
Can you please tell how i can get the logical system name for the business system updated in the Integration Directory.

When you change it in SLD and if not getting replected in the ID...make sure you run the cache again, perofmr the comeplete cache....
there is an option under the adapter specific mesage attributes compare with SLD you can click that, is nthing happening after clicking it?
Run the cache in the ID are there any errors there?
check the RWB cache monitoring is everything green there?

Logical System for RFC-Business system?

Hi,
I want use RFC adapter for my scenario like File to RFC.
The query is like, is there any importance to use Logical system for my Business System which is using for my RFC Adapter in my communication channel.
Regards
Gopi

logical system name is relevant only for Idocs, but it is always a good idea to maintain the technical and business systems with all the information you can provide.
you can check the logical system names of ABAP application servers at bd54 tx code.

ATP Check Issue - No business system could be determined for logical system

Dear all
Got an issue while executing ATP check on a planned order in product view,
with a message: "No business system could be determined for logical system"
CIF setting wise:
regular business system group maintained and assigned in place,
master data wise:
business system group info fine in product master,
Is there anywhere suggested to check under ATP setting:
category, check mode, business event, check control/check instruction?
Your kindest enlighting is appreciated,
Thank you,
mandy

Dear Mandy,
usually this error is caused by a missing customizing entry:
spro:
Integration with SAP Components
   Integration via APO Core Interface (CIF)
     Basic Settings for Creating the System Landscape
       - Maintain Business System Group
       - Assign Logical System and Queue Type :
Please read the documentation for these two transactions and create the systems.
You need to specifiy there all systems that are in your BSG. The documentation for the customizing of 'name logical system' in APO says:
To enable the transfer of data between SAP R/3 and SAP APO, you need to name both the SAP APO system in which you are working and the SAP R/3 system to which you want to transfer data as logical systems.
I hope this helps.

Tibor

Logical System Name is defined for which type of Business Sytem

hi
Can some one helps me on this question and explaination.
Logical System Name is defined for which type of Business Sytem ?
a.Third Party
b.Web AS java
c.WebAs abap
d.Standalone java
Thanks
Chandra

Hi ,
Logical System Name is defined for the Business System type WebAS ABAP.
It is used in ALE scenarios when exchanging IDOCs between the particular system and XI. The IDOC adapter will pick up the information from the SLD and it can then be used in the configuration in the Communication Channel (Adapter Specific Identifiers).
Refer to this How-To Guide for more info

Business Service and logical system naming criteria across environments

Hi !
Imagine this scenario: File-XI-IDOC. There is a file server where files are uploaded by a legacy application. XI polls that directory, converts the file to IDOC and sends it to R/3.
R/3 is a production business system, for example "R3_PROD", the file server is a business SERVICE, because of its abstract nature.
Is it ok to give that business service a name such as "BS_FileServer" and then create the logical system "LS_FileServer" in R/3, to be able to receive IDOCs from the sender business service?
If we need to use 3 different file servers, one for development, one for test and another for production...is it ok to create the business service in each integration directory with SAME name, and the 3 logical systems with same name in each R/3 receiver...because creating business services as "BS_FileServer_DEV", "BS_FileServer_TEST" and "BS_FileServer_PROD" we imagine that could give us problems when transporting scenarios from dev to test, and from test to prod...because we will need to recreate the whole scenario using the new object denomination.. e.g. a scenario including BS_FileServer_DEV in development is called BS_FileServer_TEST in test..or worse..we could have the BS object transported and as a result we would have a BS_FileServer_DEV object in integration directory of our test environment...
Is this the right path?
Thanks,
Matias.

Hey,
When a technical system is defined for a product / s/w comp version we also enter the parameter for logical system name. If a buisness system is defined for a technical system then it in turns refers to the technical system with buisness system assigned to it.
Itz lyk linkage of PRODUCT -> S/W COM VERSION -> TECHNICAL SYSTEM (LOGICAL SYSTEM) -> BUSINESS SYSTEM
As per file to idoc scenario where BUSINESS SERVICE is used it doesn't refer to technical landscape so there is no question of Business system. With relevance to transports.
With File -XI-Idoc scenario the concept of logical system only comes into picture if we have a integration process also involved in the scenario. Where in adapter specific identifiers we specify the logical system name of the sender file system.
Integration Repository.
1) The Software Component version need to be same in all the landscapes that is a prerequisite else transport will fail.
Integration Directory:
2) Assuming that transport is being done for all the objects under a service and the objects has been transported to the test landscape business service with same name will be create in test sys only address and access parameters that have to be entered again and the change list has to be activated.
I haven't tried exporting individual object from ID so no clue.
Please refer the following link<a href="http://help.sap.com/saphelp_nw04/helpdata/en/93/a3a74046033913e10000000a155106/frameset.htm">Transporting XI Objects</a> .
Hope itz helpfull.

Diffebetween Business system and Logical system...

what is the difference between Business system and Logical system...

Hi
Business system is a logical layer needed for configuration in integration directory. On the other site technical system is physical representation of your technical landscape. In case of SAP technical systems you can have more than one business system relation. In that situation there is relation one client to one business system.
If your technical system changes, then you definitely need to point this new technical system to the existing Business system which has been used to do all the Configurations in the Integration Builder.

Business System and Logical system

Hi Experts,
in SAP if we want to exchange the Data between the systems we use Logical Syestem. Why we need Logical systems basically? and Why need Business system in XI?
