Interface SAP/ABAP-Host - Non SAP/ABAP Host

Hi experts,
I need to define an interface technoloty between an ABAP-host and a Non-ABAP host.
I know, that non-abap hosts are able to call RFC-Function Modules of the ABAP-host and that I can use this method to exchange data between the systems. This means, the non-abap host starts the action.
But I don't know, how I can do it on the other way, so that the ABAP-host starts the action.
So how can I call a function/program on the non-abap host out of SAP?
Do I need to define this as an external program call in SM59?
And if so, how does the syntax needs to be look-like, which I need to implement in ABAP.
Is it an normal RFC-FM which has the destination of the SM59?
Kind regards and thank you for every tip.

Hi Christian,
SUP i.e Sybase is the interface which is used to connect non SAP to SAP system via RFC-FM. It does not require to do RFC settings through SM59.

SAP 4.7 Interface through RFC with non-sap system

We have SAP 4.7 instance and no XI and currently we are looking at following solutions using SAP connector, need following infrormation:
1. Which standard connector can be used ?
2. How Master Data to be replicated from SAP system to non-sap system( Outbound) ?
3. How Transactional data from non-sap sytem to SAP system ( Inbound)?
We need the above input considering that we don't have XI

hi ,
Can you tell me which other non-sap system you are using
either it is dot net or some other

Transferring SAP data to non-sap system

Hi All,
My client has non-sap CRM system. We have a requirement to pass material stock information from SAP system to non-sap CRM system. We don't need to update this information on instant basis. We require the update should happen twice or thrice a day.
- IDOC LOIMSO01 can be use
- Also we can use PI.
Appriciate if you give some alternative solution, like developing a program which can generate a file etc....
Thanks,
Jennifer

you need a load program in your non-sap system.
if this need to be developed by yourself anyway, then I would not develope another one in SAP for the extraction, instead I would use the standard MB52 stock report and download the result as textfile. And subsequently read this text file to load into your non-sap-system

How to connect one SAP system to Non-SAP system(Example:Window's7)?

Hi Experts,
In general, One SAP system can connect another SAP system through RFC.How to connect One SAP system to Non-SAP system(example:window's 7) and is it possible through RFC?
Thanks and Regards,

Hello Wolfgang Schaper,
Thank you so much for quick response.
As you told I am trying to work with BRFplus/DSM to call decision services from nonABAP systems,so I tried with RFC.But it is not possible as you told.
Please give any solution Without using Web Services, is there any ways to connect from SAP system with the Non-SAP Systems.

Hi,
you can create the same...
but normal practice what we do is create swc for each system so that it is easy to maintain and easy to extend in the future..
or else follow some conventions if you are just starting the things..

Integration of SAP XI and none SAP tools

Hi!
I would like to start working with SAP XI.
Where can I find the Step by Step case studies describing different SAP XI scenarios (IDOC/ALE, RFC, File, etc.).
What is the most famous example of integration of SAP XI and none SAP tools?
Are there tool free of charge and can be downloaded?
Thank you very much!

SAP to External Non SAP Systems C++ Connections

Hi guys,
i should develop a C++ application that should transfer/receive data from an external Non SAP System to a SAP System (MM SD FI Modules) and viceversa,
This bidirectional integration should be synchronous and asynchronous, depending on the data flow type,
I was thinking to use IDocs for this communications,
I should be able to send purchase and sell orders requests from the Non Sap System to the Sap system and receive the result of SAP processes once the SAP transactions will be finished.
So i'll have a C++ process that send idocs (created with sdk end sent throught RFC to SAP) for SD or MM operations and a SAP Abap module that receive this idocs and start internal operations.
After this i need an internal SAP abap module that send to my external application Idoc's with the result of internal operations.
Are the idocs the common way to transfer data(low cadinality) in this scenario, or there is a better way?
Note: my sap system versions are previous to the netweaver release, so i can't use a Service Oriented comunication...
Thanks in advance!!!

Hi,
try sending the data through BAPI Function Module.
and use the FM in your C++ program.
hope this works....
try
best of luck!!

Data load into SAP ECC from Non SAP system

Hi Experts,
I am very new to BODS and I have want to load historical data from non SAP source system into SAP R/3 tables like VBAK,VBAP using BODS, Can you please provide steps/documents or guidelines on how to achieve this.
Regards,
Monil

Hi
In order to load into SAP you have the following options
1. Use IDocs. There are several standard IDocs in ECC for specific objects (MATMAS for materials, DEBMAS for customers, etc., ) You can generate and send IDocs as messages to the SAP Target using BODS.
2. Use LSMW programs to load into SAP Target. These programs will require input files generated in specific layouts generated using BODS.
3. Direct Input - The direct input method is to write ABAP programs targetting on specific tables. This approach is very complex and hence a lot of thought process needs to be applied.
The OSS Notes supplied in previous messages are all excellent guidance to steer you in the right direction on the choice of load, etc.,
However, the data load into SAP needs to be object specific. So targetting merely the sales tables will not help as the sales document data held in VBAK and VBAP tables you mentioned are related to Articles. These tables will hold sales document data for already created articles. So if you want to specifically target these tables, then you may need to prepare an LSMW program for the purpose.
To answer your question on whether it is possible to load objects like Materials, customers, vendors etc using BODS, it is yes you can.
Below is a standard list of IDocs that you can use for this purpose to load into SAP ECC system from a non SAP system.
Customer Master - DEBMAS
Article Master - ARTMAS
Material Master - MATMAS
Vendor Master - CREMAS
Purchase Info Records (PIR) - INFREC
The list is endless.........
In order to achieve this, you will need to get the functional design consultants to provide ETL mapping for the legacy data to IDoc target schema and fields (better to ahve sa tech table names and fields too). You should then prepare the data after putting it through the standard check table validations for each object along with any business specific conversion rules and validations applied. Having prepared this data, you can either generate flat file output for load into SAP using LSMW programs or generate IDoc messages to the target SAPsystem.
If you are going to post IDocs directly into SAP target using BODS, you will need to create a partner profile for BODS to send IDocs and define the IDocs you need as inbound IDocs. There are few more setings like RFC connectivity, authorizations etc, in order for BODS to successfully send IDocs into the SAP Target.
Do let me know if you need more info on any specific queries or issues you may encounter.
kind regards

Triggering SAP workflow from non-SAP system

I am trying to use WF-XML to trigger a workflow in SAP from non-SAP system.
I have already created a workflow template in SAP and want to test the scenario if this will be really hit by the incoming xml message.
Questions:
1. How the data from incoming xml is tranferred to workflow container element? IF system does it, how is done? If not how to address it?
2. Do we have some tool here, to simulate this situation - to create a test xml incoming message with SAP and really see if that triggers the desired workflow template. Pupose is testing the scenario first in SAP and then going to the other system to test the real interface.
This is somewhat similar that we see in incoming IDoc. In Idoc we can simulate the incoming IDoc structure and test.
Is any one here who can guide on this?
Thanks in advance.
Rgds.

Hi,
You don't need a triggering event. In the xml it says which workflow should be started. You don't need a class to fill the container. The service does this.
I think there is a way to generate an example xml but I don't know exactly how. In the <a href="http://help.sap.com/saphelp_nw70/helpdata/en/54/de9e3887d6174fe10000009b38f842/frameset.htm">SAPHelp</a> there are some examples of the documents. Check also the entry above it about the creation of a WF_XML document. In the first and third example it shows a container element and its value (QUESTION).
Try to get a copy of the book "Practical workflow for SAP" by Alan Rickayzen. It has got a part about this.
Also check this link from the SAPHelp:

SAP IDOC - XI - NON SAP IDOC (tRFC)

Hi all,
our scenario is as follows:
1) SAP ERP 2005 send an IDOC to XI (NW04S, 7.0)
2) XI dos nothing, just routing. So no mapping or stuff like that
3) XI should send the IDOc to a non SAP System via a tRFC (registered program id)
a) IDOC can be sent to XI and for test we introduced a file adapter. The IDOC is written to the file system successfully.
b) tRFC is registered connection test ok to the NON SAP System.
c) SLD is maintained with a NON SAP technical and a business system
d) Which adapter to use?
- IDOC Adapter (following error)

If I set the IDXNOALE the message is succesfully processed but not received by the NON SAP system which is connected to the same tRFC.
I do not know how to set this scenario, any ideas?
Thanks
BR Markus

Hi all,
at first thanks for the fast reply.
I do not use any kind of mapping, so the message should be prozessed through without any changes.
So two questions:
1) Where to set the exactly once, ...?
2) Where to set the return paramaters?
Inside the SLD the logical system name is configured. I had the settings maintained like Sergio wrote it.
I changed my configuration to the following:
- No Party
- No Business System
- Creation of a Business Service with the same Logical System as configured in the Bus of SLD
-> Everything works all right
So I created the scenario with No Party but again with the Bus and everything was all right, so.
I had any error in the first scenario but I do not know which one, too many thing changed during the process of problem solving.
Thanks a lot anyway.

Extract Tables/views into ECC 5.0 SAP system from Non-SAP system

Hi,
I am looking for some inputs on how to set up the following scenario of extracting data stored in tables/views in a non-sap external system into my SAP ECC 5.0 SAP database.
Currently we are using a middleware between SAP and the external system to fetch data. I would like to get rid of the middleware and set up a scenario to call this non-sap external system and pull data stored in views into our SAP system directly. Is that possible in SAP version 5.0? If yes let me know the steps to be performed... do I need to set up XI ?

maybe you can access sap data using some connector such as java or .net connector.

Integrate or connect SAP system to non-SAP system

Hi All,
We need to connect SAP system or integrate inspHire rental software to SAP. Do you know the process or initial summary on how to integrate this one?
As of now, the only way that we know to integrate SAP to non-SAP for posting is thru LSMW and batch input.
your suggestions will be greatly appreciated.

Hi,
LSMW is just tools for integration and you can use BDC Call Transaction, BDC session or BAPI, or Function to update something ins SAP.
1/Easier is if your non-SAP system is able to create file and ftp to SAP folder.
2/You will have background job running program that will every 5minutes or hour or daily(it is up to you how fast dat has to be bring to SAP) check if file was create in SAP folder.
3/Program will move file to folder in process
4/Program will process file, usinf function, or call transaction to update SAP on the base of file
5/Program will move file to process folder
If you need more info give me detail about what you would like to update in SAP and I could send you code.

Migration of SAP Workflow to non-SAP system

Hi All,
If there is a SAP Standard or custom Business Workflow in SAP system and if we want to implement the same business flow in some non-SAP system(EX: Oracle Apps,Workflow tools etc.,) where Workflows can be used...
Can we migrate the SAP workflow into that system (non-SAP) by converting to the SAP Workflow template in xml or other format that supports the non-SAP system?
Can the above said scenario be done?
Or what is the process of Migrations of Workflows from SAP to non-SAP or Vice versa.?
Thanks in advance
Hraish Kollipara

Hi,
From your posting what I can understand is you want to model the same Process in other System e.g. Oracle Apps which is already modeled and working properly in SAP system. I wonder if its possible to download the template from a system and use it in other. As per my knowledge every system has its own development Engine which is configured to work in a specified way. So if its possible then its really time saving.

Vaishali.

Installing Oracle for SAP on existing non-SAP RDBMS

The title says it all -
I haven't been able to find any real docs supporting or not supporting the practice of using an existing Oracle 10.2 RDBMS to add an SAP DB. I know it's technically possible, but since the SAP Oracle installer is configured to build a new RDBMS for each SAP instance/DB installation, I'm wondering if it can be altered and piggy back on an existing one.
The reason is I have a customer who would like to do this so they can continue to use an existing DEV Oracle server without adding the stress of an indepedent set of oracle binaries running, and consuming resources.

> But aside from that - let's assume the release and patch levels from their own DBs are equal to the requirements from SAP. What other considerations/issues/supportabilty problems might be encountered?
If it's not a production system you could certainly go for it.
I think though, that it's MUCH LESS maintenance work using a second ORACLE_HOME than to try to fiddle with the huge amount of single/interim patches SAP requires. If you just check
Note 871096 - Oracle 10.2.0: Patches/patch collections for Oracle 10.2.0.2 (59 interim patches)
Note 1137346 - Oracle 10.2.0: Patches/patch collections for Oracle 10.2.0.4 (39 interim patches)
I can imagine you having a pretty hard time aligning that with the other non-SAP databases. On top may come incompatibilities with OPatch (SAP uses a "special OPatch") where you may need to switch between the official one and the "SAP-one" depending on which patch you install.
The only additional resources the new ORACLE_HOME uses is harddisk space (some GB) - which shouldn't be more expensive than the work you'll need to invest to keep the system and working for both.
Technically it can be done - certainly.

Provision UserID/Password from SAP Ssyetm to Non-SAP System

Hi,
I have a requirement to be able to provision UserID & Password from a SAP ECC6 system to a non-SAP thick client application. All interactions between ECC6 & the non-SAP Application will be via SAP PI. (SAP EEC6 <-> SAP PI <-> Non-SAP App)
Our landscape includes:
SAP ECC6
SAP BI
SAP PI
SAP SOLMAN
SAP Portal
non-SAP App
SAP IdM has been ruled out due to budget constraints, Active Directory is not suitable due to the requirement that the non-SAP application must be able to authenticate users if the WAN/LAN is down.
Yes, we could simply maintain the users in both systems, but for the time being that has been deemed not appropriate.
I have thought about using CUA on SOLMAN to provision to the SAP Systems & then use SAP PI somehow to provision to the non-SAP App, but I have no idea how to pass the raw user password through SAP PI.
If anyone has any ideas or can point me to links where I can do further research would be much appreciated.
Thanks in advance,
Stephen Hall

The search term "password AND synchronize" will help you further to find "flamewars" from the past.
You cannot send "raw" passwords from CUA, as the password is represented by a "one way" hash which is not decryptable by mortals, but rather the "raw" password is encrypted and the hashes are compared locally. Non-SAP systems cannot do this... (bar trial-and-error).
A better option would be to use a SSO mechanism. This is very easy within SAP.
For bi-directional authentication with non-SAP you will face some challanges...
The easiest option is to re-use a PKI certificate based authentication or re-use the native Kerberos authentication available for Windows bases PCs.
In the SAP --> non-SAP direction you can consider using a verification library to extract the user name - but that is not "state of the art" and if such a UID should be encrypted then have fun...
In the non-SAP --> SAP direction you are best off forgeting about the infrastructure trust or worste-case-scenario is a password sync. Rather re-authenticate the caller using a realm which already exist.
Active Directory is not suitable due to the requirement that the non-SAP application must be able to authenticate users if the WAN/LAN is down.
I would consider an application specific password self-service as a failover only and go for the AD or an "identity provider" which your applications trust as a service.
If your AD or entire network goes down you will probably be in bigger trouble than passwords... so you should not expose "raw" passwords during normal operations for this eventuality...

Julius
