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 ?

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!!

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

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).

BPM--cannot convert sender logical system to ALE

Hi
My Scenario is file-bpm-idoc.. Where i am getting an error saying "cannot convert sender logical system to ALE" for the BPM.
i tried entering the logical system for the BPM in adapter specific attributes but it says logical system is already being used by some other service..
So i tried header mapping in receiver agreement now the messages are failed at the intital stage before entering the BPM only only saying cannnot find recvr agreement..
My sender system BS_EXT_100
BPM IP_calldoc
Recvr system BS_EDCR/3_200
i did the header mapping for recvr agreement of BPM by selecting the sender service and entering "BS_EXT_100"
Where am i going wrong...

solved it myself.. Thanks

What is logical system?

Hi all,
What is the logical system name? Is it the same "source system name"? It shows when I try to create a R3 datasource in BW. Thank you.
Thank you for everyone who answered my questions before. I assigned the points to you and didn't get chance to email for thank you.

Hi!
You need to maintain basic settigs for ALE for this
and what do you want to see...
you can see the logical system names available in any sap system under.In SPRO ->

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.

Setting up Logical system in ALE Config !

Hi,
I have set up the ALE logical system in SAP to transfer data. Basically RFC destination setting. While I am trying to test the connection, I am getting an Error Program INBOUNDASYNC not registered.
Could any one help me out here.
Thanks,
Senthil

Hello,
Please make sure you have completed the starting of SMD agent also after the setup, u can find it in the guide.
also check the p4 or Https port number is correctly mentioned.
The user and pass mostly would be that of SMDadmin, created during the setup, or u can use SIDADM which will wrk fine.
sometimes root needs to be used as even sidadm can be restricted in ur envt. ( just in case).

Logical systems for ALE

HI all,
I'm configuring for an IDoc to be generated and downloaded to a file via a file port.
This IDoc is of message type PAYEXT.
The file is to be sent ot the bank via the meansa of third party software.
Do I have to create logical systems for these? Or only the outbound logical system?
Do I also need to set up the distribution model , and if so, how far do i need to set it up?
Points wil be awarded. Thanks!

Hi
Use BD64 Tcode to setup distribution Model
Define the 2 logical systems.
see the flow:
Outbound:
Step 1. Application document is created when transaction is saved.
         2. Message control is invoked.
         3. Messages are processed by system.
         4. Messages are Edited (if desired).
         5. Output (ALE / EDI) is checked
         6. Validate against Message control record from Partner Profile
         7. Application Document is saved.
         8. Entry NAST table is created for every selected output program
              along with Medium & Timing.
         9. Check for Process Immediately .
                 If (yes)
                   Determine Processing Program from TNAPR Table.
                 ELSE
                   Execute RSNASTED Program.
       10. Read Partner Profile to determine Process Code.
       11. Process Code points to the Function Module & Invoked.
       12. IDoc is generated.
       13. Check for ALE Request.
                    if (Yes)
                        Perform Filters, Conversions, Version Changes etc.
                    Else.
                        IDoc is stored in DATABASE.
INBOUND:
Step 1. EDI Subsystem creates an IDoc file from EDI Messages
        2.   Subsystem calls Functional Module                                 EDI_DATA_INCOMING from startRFC program.
         3. Data in Control Record is validate against the Partner                       Profile.
        4. IDoc is generated in Database and syntax check is                      carried out.
        5. IDoc file is deleted once file read.
        6. Event PROCESSSTATE REACHED is triggered in Idoc Object Workflow.
                   7. Check for Process Immediately.
               If NO
                 Execute RBDAPP01 Program
               Else
                  Read Process Code from Partner Profile
                       Process Code Points to Function Module
                 Application Document Posted.

Partner profile...port....logical system....!!!!!!!

Hello Everyone,
few stupid questions came to my mind but no document cleard it, so thought that someone might throw some light on this.
<b>
What is logical system in R/3 and why do we create that ?
what do we mean by partner profile and what is its significance?
what is use of port...???</b>
<u>these all three parameters we look when we create outbound IDOCs for IDOC to file (of any other) scenario.</u>
thanks,
Pranav

Hi Pranav,
What is logical system in R/3 and why do we create that ?
A logical system is your R/3 address where you can distribute data to and from an R/3 system.
http://download-west.oracle.com/docs/cd/B10464_05/integrate.904/b10299/ale.htm This link gives you a better idea of a logical system.
what do we mean by partner profile and what is its significance?
Based on an existing logical system, a partner profile is an identifier for a system used for communicating messages.
http://download-east.oracle.com/docs/cd/B10465_01/integrate.904/b10408/ale.htm gives you a very good idea regarding partner profiles and ports.
Hope these help,
Regards

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 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)

Setup Logical System from blank

the default logical system of client 100 is blank
now we have to set a logical system for ALE and BW data transfer
but we found that some documents will not be transfer and some document cound not be found
eg: we cant found the FI documents from material document as MB53
debug the program we found that the programe check the logical system
is there any way to change the old documents logical system to new?
i found there is a sap note to describe how to change the logical system from a old value to new
but it not suit the situation of set new logical system from blank value.

HI ,
You need to create the logical system name and assign that to that client.
This can be done in Transaction :SALE.
Have a look at the t-code SALE and its options....
SALE->Basic settings->Logical system---- we have three options.
one is for creation ,assigning itto client ,other one is coversion.:Last one is only called BDLS .(little critical)
Thanks.

Is Logical System required for Solution Manager to work?

Hi all
We will be upgrading to SAP ERP in the near future and will have to use Solution Manager.
We only have one company code and no business areas in our configuration. So that, we do not need ALE, consequently, we have not defined/used a logical system.
Do we now need to define a logical system and assign our client to it, in order to use Solution Manager?
tia
Manuel

Hi Manuel,
in logical components the term "Logical System" is used to discribe the combination of system and client in an ABAP system. This does not mean you have to define logical systems in ALE customizing. That is not required as far as I know.

Andreas
