Single Portal to connect to multiple back end ECC system

Hi Experts,
I want to connect existing SAP Portal 7.3 to new ECC(ECC EHP 5) System for ESS MSS.
The requirement is that my existing backend system (ECC EHP 5 ) should also exist. i.e. I should able to use current portal to connect to existing SAP ECC System as well as new ECC System with single portal .
Please let me know how it works in ABAP Webdynpro?
Do let me know how this can be achieved ? Is the same portal url be used to access the 2 different backend system for ESS MSS.
-Pravesh

Hi Pravesh,
for using different backend systems in the same portal, just adapt these systems in your system landscape and define your system aliases in appropriate iViews or write a DSR service.

How to connect to MySQL back end in Syclo Agentry?

Hello All,
       I have worked on Syclo agentry with Non-SAP back end (MsSQL) and with SAP back end(Work Manager App).
       But now I wanted to connect with MySQL Back end, I know that it is possible, because Syclo can deal with Oracle,IBM Maximo, MsSql and SAP(ERP,CRM...etc)
       But how to connect with MySQL Back end. What is the procedure and the Configuration changes.
       Could anyone help me out to find the way.
Thanks,
Swaroopa.

Swaroopa,
You may also need to create/define your database globals if you are using SDML database tags in your queries. For example <<database.getSystemTime>> will evaluate differently for MySQL compared to SqlServer or Oracle
You will want to create a mysql_sd.ini file containing the various database SDML tags and their corresponding MySql values. I would suggest copying the sqlserver_sd.ini and then update based on mysql syntax.
You will then want to update your Agentry.ini queryConstantFiles entry for the mySql backend settings to point to your new filename.

How can I get connection between VC and back end ABAP system

Hi, I'm developing the kits in the VC platform, and I need to access the back end system designed by ABAP. For example, the system provides some public functions(not web services), and I hope when I click the "search" button, the VC front can call the remote functions and get the data from the back end system. In addition to that, the most important is I must keep the connection real-time. How can I do it?

Thanks for your help. At present, my VC version is 7.1.4 which isn't installed in the portal server but in local machine, and I'm new in the VC. What I want is when I click the "search" button(in the properties pannel), I can get the data from the remote server. I know the VC 6 provides similar functions, but the current version doesn't. Could you explain the details of how to get and keep the connection between them? Thanks so much.

Connection between CRM back end and ASP front end website for Ecommerce

Hi All,
I want to establish the connection between a ASP website and CRM back end server(we are replacing th existing ERP back end system with SAP CRM ).
I want to know whether I have to go with XI or any other connectors provided by SAP to establsih the communication between the existing ASP website and CRM back end server..
Can anyone please help me out.
Thank you,

Okay here is the general concept for your scenario:
-You will call standard/custom RFC's(could be BAPI's) in the CRM system from the existing application.
-You will need to write a new model layer in your ASP application that calls the RFC layer in CRM
-You decide what data you want to use from CRM in your application
Let's assume at minimum you will want to use the product master, business partner master, and business transactions. You will need RFC's/BAPI's for every interaction point where you will consume/publish data to CRM.
So when an user creates an order from your e-commerce site, you will need to support saving an order in CRM. This is example of how you need to map out each function in your existing site to a part of the CRM system. Since we don't know what your site currently does, this is something you would have to do.
Once you have mapped out the business level data to the CRM system, then you can evaluate where you will need a BAPI and/or RFC call. Once that is done, then you can look at the CRM system and see what standard pieces can be called. Then everything else is custom development. Your ASP application will call CRM via RFC.
It is possible to do what you want to do, but it is going to require a lot mapping work and a fair amount of development effort to integrate the two pieces. I don't know if you might be better off looking at the SAP Internet Sales Solution instead so you could focus only customizing that application, instead of worrying about an integration problem. It just depends on how much special functionality your existing e-commerce site has today.
My general recommendation would be for you to hire a consultant that has done an SAP e-commerce project using SAP CRM in the past and let them guide you on the implementation issues. An on-site resource could better answer your "high-level" questions.
However if you have more questions please ask and I will try to answer to the best of my knowledge.
Good luck,
Stephen

Two SRM systems connected to One back end system

Hi..
Note: I have posted this message earlier ......but couldn't find that. I am just reposting the message:
In our quality environment, we have two SRM and two backend systems. One for testing purpose and other for training purpose. We are planning to remove one back end system and connect both the SRM systems to one backend system.
1. Is it possible to have this landscape?
2. In SRM & R/3 we can define two RFC connnections but from R/3 side, I am not sure how the system will determine the respective RFC connection during GR or any other process.
3. Are there any other difficulties?
We are in SRM 4.0 using Extended classic scenario. We are using SRM for processing shopping cart, Po and confirmations.
Please advise.
Thanks.

Hi Prashanth,
is very much possible.
for this you need to configure the partner profiles.
need to define port
need to configure inbound paramters and outbound parameters.
we20 - create partner profiles.
define outbound parameters and inbound parameters of the message type.
we21 - define port.
under Transactional RFC.
and create a distribution model and add message type.
revert back to me if any problem still you find.

How to develop portal application connecting to SAP R/3(backend system)

Hello Everyone,
Can anyone guide me on how to create portal aplication(JSPDYNPAGE), that will connect to backend SAP R/3 system, & it will fetch the data from some table from that R/3 system. Any reference material will be appriciated, it will be of great help.
Thanks
Chetan.

Hi Chetan,
Connection to R/3 systems through Portal can be done in many ways. Since you have mentioned that you are using jspdynpage then its better that you use JCo for connecting to R/3 system.
U can write the JCo code using the jspdynpage component. I hope you have pdfs related to JCO. Incase u dont have then give me you mail id. OK
Another approach could be developing a web dynpro java application that access a r/3 table using a BAPI. You can a dynpro model to easily connect to R/3 system.
Just develop an iview based on this web dynpro application. And finally navigate to this iview through your jspdynpage.
I hope this helps you in some way

Connect CRM multiple clients to ECC

Hi SAP Gurus,
I have one Question regarding CRM->ECC connectivity.
Will it be possible to connect multiple clients of CRM to ECC ? Like more than one client can talk to ECC ?
Because in BW we can not connect multiple clients to source system ! does this true with CRM also or not ?
Thank you

1) As datasources are client independent so do we need to activate the datasources (like 2lis*) in all clients one by one? or just activating in one client will make it ?
You need to activate the datasources individually for all the client. If you will activate in one client, it will be specific to that only
) If we replicate the datasources for new clients in BW side and then want to reload the data from New clients (set-up tables filling and INIT)?would it have an affect on existing deltas (for datasources 2lis*)for existing Source client 100? What shud be the precautions? How we can proceed?Please let us know your opinons plz
If you will replicate in one client system, it wont affect delta and init from other client.
One thing you can do, to identify data from different source systems, you can use source system compounding in your infoobjects. Make sure you are not loading data from both the client at the same time. it may lock the DSO and master data.

How to not update the model value whe, multiple back-end validation failed

Hello !
I have a save button who perform in backend code multiple validations on some fields. The validations can be ok, if not, I show specific error messages in my page. It's working fine.
The problem is that all the InputText I need to valid are value binded with value=#{backing.somepropery} to the model and when the code of the ActionEvent is called the model was already update.
So the validation is useless, you see error message ok but I can't prevent action to be done.
As the validation occurs only when I press a specific button I can't use custom validator.
does someone have an idea to manage that ?
Thank You.
Dan.

Thnaks for your repsonse but, it"s not working because the values are bound so the modifications are already done.
I'm sure that there is a way to do that.

ACK_ channel for handling ALEAUD back to ECC system

Hi,
I have created a channel called ACK_Receiver_XI_TO_ECC for sending ALEAUD for all IDOC's that are received from ECC to XI. I also have another receiver IDOC channel for all IDOCs that are sent from XI to ECC. I read in one of the pdf's that when there are multiple receiver IDOC communcation channels, the one starting with Ack_ is chosen to send the ALEAUD. But in my case, in Development and QA system it is correctly picking the Ack_.. channel but in production it is picking the other receiver IDOC communication channel. Any ideas why and how this can be rectified? I have the "Restore original parties.." option checked on the Ack_.. one and not on the other so the selection of the other in production is giving me the "Unable to convert sender service to ALE logical system" error.
Thanks
ram

Hi Ram,
>I also have another receiver IDOC channel for all IDOCs that are sent from XI to ECC. I read in one of the pdf's that when there are multiple receiver IDOC communcation channels, the one starting with Ack_ is chosen to send the ALEAUD
I dont think so, the channel will be determined by the Receiver Agreement. If you have more than one what are valid for a message, that is take which is less generic. For example, if you have 2 Receiver Determinations and you type in the first at Receiver Interface a joker (*) and in the second for Receiver Interface a certain value the second Receiver Determination will determine the channel. This is a general rule for IB objects and allows to create generic rules but having exceptions.
Please compare the Receiver Determinations in the different transport layers.
"Unable to convert sender service to ALE logical system" means, that your sending system has no value for logical system. Control that at Business Component, Adapter Specific Identifier. If the sender is Business System, correct that at SLD and reimport the system.

Udo

User,Role Sync with back end Error.

Hello,
I am connecting a new back end ECC system for an existing RAR system with 2 backend systems.
I get the following error message. I have configured the Jco to the new system and it tests O.K.
" Error while executing the Job:Interface Controller does not exist for Component Instance "
Is it an configuration issue with the RTA at the back end ?
Thanks
Vidyar

Hello ,
Please check the following steps for the error.
1. Make sure that SLD is up and running.
2. JCO's are properly configured and are successfully pinged and tested.
3. After verifying the above steps, Restart the J2EE server.
TEST & PING the JCO in Web Dynpro =>Content Administrator =>Maintain JCOs. This JCO has to be the one which you are using for the connector for which you are running the SYNC job.
Periodically the JCo destinations, as part of the Netweaver framework, sometimes fail. Recreating them or restarting the system can make them work again.
