Enterprise Services and webMethods

I have an environment utilising webMethods as the integration tool for SAP-nonSAP integrations.
My question relates to the future roadmap for enterprise services (ESB and enterprise services repository and registry). Do I utilise SAP PI 7.1 as the enterprise services bus or utilse the webMethods environment?
The reason why I am leaning towards SAP PI is that most of the enterprise services which will be exposed will be from the SAP environment. How would SAP PI manage the existing integrations that use webMethods and how much work would be involved in exposing these are services?
From a BPM and BAM perspective, would the PI enterprise services environment be able to monitor and interrogate the webMethods processes?

Enterprise Services and PI

I am looking for some white papers / blogs on calling SAP Enterprise Services via PI. I would also like to get sdome idea of the following points:
1) A typical scenario using Enterprise Services
2) Is it possible to extend Enterprise Services as one might a BAPI, in order to enhance it specifically for a customer?
3) What is the performance like compared to posting IDocs via PI?
4) Is it better to call Enterprise Services via XI, or directly into the ERP system?
Kind Regards,
Tony.

Enterprise Services and Persistence

Hi All,
One of the useful things about IDocs is that their processing involves 2 steps: 1) persisting the IDoc to a database 2) processing the document. Persisting IDocs is very useful since it allows you to edit and resend them.
I would like to know if SAP asynchronous Enterprise Services can/do provide persistence as well. Knowing this would help us decide between using IDocs or Enterprise Services in future developments.
Your help is very much appreciated.
Cheers
Gerard

Dear Gerard
SAP's asynchronous Enterprise Services uses proxy technology which provides persistence in the local integration engine. It is similar to IDocs, whereby the message data is persisted prior to processing by the application logic.
Additionally, SAP-delivered Enterprise Services uses Forward Error Handling (FEH) framework to enable error handling capabilities like editing and resending. Together with Error Conflict Handler (ECH) and Post-Processing Office (PPO), this enables capabilities similar to IDoc error handling.
For more info on FEH/ECH/PPO, you can check the below wiki and blog post
Error and Conflict Handler (ECH) - ABAP Connectivity - SCN Wiki
Michal's Tips: SXMB_MONI vs FEH/ECH vs AIF
I've also blogged about development of custom asynchronous proxies utilizing FEH/ECH/PPO. You can check the blog below for an example of how persistence in the integration engine is, as well as the editing and reprocessing features.

Enterprise services and Web services

Hi Everyone
I need documents about Invoking enterprise services from Netweaver PI and web services from Netweaver PI, I can find only NetWeaver CE, but not PI. So help, any links?? or pdfs?? or ideal would be some demo example of invoking a web service using PI.
Thank you

How to map business process and enterprise service?

Recently, I read some documents about ESA. I'm confusing about the relationship between business process and enterprise service. In other word, how to map the business process to enterprise service after the business process is analyzed? Is there any methodology/rule to define business process and wrap them into service in ESA?

Hi Sherry,
I like to add some of my thoughts about that discussion. From my point of view ESA is much more than just another BPM or Enterprise BPM. ESA is adresses six key areas and I think all of them are really needed:
- People Productivity as the word itself describes...it's about portals and productivity.
- Embedded Analytics has to integrate transactional and analytical content.
- Service Composition is used for model-driven service composition and services orchestration.
- Service Enablement is about a Enterprise Services Repository filled with business meaningful Enterprise Services and service patterns for enabled objects. Excactly this is where SAP has years of experiences.
- Business Process Platform is about service enablement of all application platform objects and engines. This is the place where "BPM" for core business processes resits.
- Life-Cycle Management has to cover the deployment, configuration, operation and change management for ESA based processes.
Therefore the term "BPM" is located in serveral layers of an ESA approach. On the level of Business Process Platform BPM is providing the choreography for core business preocesses.
At Service Enablement BPM needs to compose out of granular services (I would say "atomic" services)
buiness meaningful services (here we have "molecular" services).
The third level where BPM could be used is Service Composition because exactly this is the place
where serveral Enterprise Services could be combined to a process representation.
To come back to the discussion:
1. The question should be how to indentify business meaningful services which could represent single process steps. ATP check, Credit card check, ... could be examples. In theory this service could be out-tasked, defined more flexible etc. This means that processes needs to be evaluated for Enterprise Service candidates. Afterwards you can check against SAP's Enterprise Services Repository for already existing Enterprise Services. The evalution for enterprise services candidates will be supported by the metodology mentioned by Kaj and David.
2. I think domains in this context should be motivated by business and/or functional areas. Depending on the granularity. For example Order Fulfilment Services, Master Data Services, Search Services... These kind of serices can be combined again to services such as "Search of Master Data" (Search Service + Read Master Data Service) etc. or can be used to generate UI to be used in a ESA application.
Your thoughts?
Very best regards
Wulff

Enterprise Services, Service Operations and Functional Business Component

Hi,
in the Enterprise Service desing guide (see https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/40c05360-0501-0010-63bd-aedd415b6e05 ) the relations between Enterprise Services and Service Operations are covered.
I understand that one Enterprise Service consists of one or more Service Operations. For Example General Ledger Processing ES offers seven Service Operations. (See Solution Composer)
Functional Business Components offer one or more Enterprise Services and several Service Operations. As mentioned in the Design Guide, an Enterprise Services is dedicated to a certain Functional Business Component. An Enterprise Service could use several Service Operations of one ore more Functional Business Components.
When browsing the Solution Composer I couldn't discover any Enterprise Service that uses Service Operations of more than one Functional Component.
Here's my question: Does anyone know an Enterprise Service described in the Solution Composer which uses Service Operations of several Functional Business Components? If there aren't any, why?
Regards,
Sebastian

Sebastian,
I haven't looked through the entire set of preview services, but most of what I have seen is consistent with what you are describing. I think the short answer is the ESA preview system is really a pre-release of the intial ESR which itself is essentially an extension of XI's integration repository. These are basically the finer grained object and interface level services.
SAP should be releasing some significant content updates to this ESR after NW2004S goes GA later this year. More importantly the next edition of the ESR tied to the BPP release will greatly expand on the scope including containing the more complex service defintions and process models which cut across components that you are looking for.

Difference between Webservice and Enterprise Service

Hi all,
In SAP, web service is known as Enterprise Service. What makes Enterprise Service different from a normal web service?

Hi,
Enterprise Service is a web service with business semantics.
The tecnology is same i.e HTTP,SOAP,WSDL.
But there are some governance rule for defining an Enterprise Service and it can be defined only in ESR(using business objects, process components etc).
There are no such governance rule for defining a web service. You can simply write a mehtod/functional module to add two nos and expose it as a web service . But would not be called as Enterprise Service.
Hope this helps.

Piyush

Understand the technical base for Enterprise Services?

Hi all,
I am trying to understand what is the technical base for enterprise services and the restrictions when activating them. The best documents I have found are:
Note 1566412 u2013 Enhancement package 6 for SAP ERP 6.0.
Note 1359215 u2013 Technical prerequisites for using enterprise services
sdn blog u201CDetermin the SOA readiness of your System with the ES Workplace (Part 1 and 2)
EHP Master Guide - https://websmp107.sap-ag.de/~sapidb/011000358700001183052011E
The documents are quite informative, however there are still questions. Maybe someone can shed some light of these:
1.) Is my understanding correct that Enterprise services can have three different base u201Cmodulesu201D?:
a. An EHP (with relation to a business function).
b. The swc u201CESA ECC-SE 60xu201D (without relation to a business function). E.G. ES Bundle "Bank Communication Management".
c. The SWC u201CSAP APPLu201D (without relation to a business function). E.G. u201CBusinessPartnerERPUpdateRequestConfirmation_Inu201D
2.) Is it possible to activate enterprise services (bundles) that rely on business functions after a EHP installation or ONLY during the EHP installation?
3.) Is it possible to activate enterprise services with base u201CESA ECC-SE 60xu201D after a EHP installation or ONLY during the EHP installation?
4.) Is SWC u201CESA ECC-SE 60xu201D a u201Ctechnicalu201D business function, whose activation cannot be reverted either? If yes what effect has the activation von u201CESA ECC-SE 60xu201D on the current ERP customizing?
5.) How do the Enterprise Services relate with Service Interface definitions from SAP Process Integration (XI Content)?
Do I need the XI Content with the service interfaces in ES Repository (and SPROXY) only if the communication is B2B (with PI) or also if the communication is Point-2-Point (without PI)?
Thanks for your feedback!
Chris

Hi Chris,
I'll try and provide answers where I can...
1.) Is my understanding correct that Enterprise services can have three different base u201Cmodulesu201D?:
I personally don't agree with this understanding. Enterprise Services would always relate to some or other business function, unless we have a different understanding of what "Business Function" means . What changes is how the Enterprise Services (or versions of them) are delivered.
SAP APPL for example would be relevant to most of the enterprise services shipped with a standard ECC EHP*. So it will relate to the business functionality for the applications that are shipped with an ECC installation.
2.) Is it possible to activate enterprise services (bundles) that rely on business functions after a EHP installation or ONLY during the EHP installation?
I don't understand this question but I'll try and offer a generic answer. You can activate/use Enterprise Services whenever you want to as long as they are already available in your current installation. If they are only available in an EHP that you don't have yet then you will need to upgrade (but I also seem to recall some workarounds - SAP notes - as an alternative to upgrading).
3.) Is it possible to activate enterprise services with base u201CESA ECC-SE 60xu201D after a EHP installation or ONLY during the EHP installation?
You decide when you would like to activate it, it's generally after. SAP will ship them anyway.
4.) Is SWC u201CESA ECC-SE 60xu201D a u201Ctechnicalu201D business function, whose activation cannot be reverted either? If yes what effect has the activation von u201CESA ECC-SE 60xu201D on the current ERP customizing?
There is a tool call Impact Analyzer, read up a little on it. It allows you to do an impact analysis before activating. It might also help posting a separate thread on of the ECC functional forums here on SCN for more impact analysis. I'm not sure if the activation can be reverted.
5.) How do the Enterprise Services relate with Service Interface definitions from SAP Process Integration (XI Content)?
The XI Content is the design equivalent of the Enterprise Services as you see them in SPROXY. It's only relevant in certain cases, examples:
- If you want to enhance standard SAP Enterprise Services
- If you want to do additional transformation/s & routing.
If you are planning P2P type communication, then the XI content is not relevant. One thing to be aware of though is if you have your backend ECC system connected to your PI ESR, the view that you get in SPROXY will reflect the SWC view of the ESR. So you might want to download the XI Content & import it into your PI ESR anyway.

Enterprise Service Repository

Hi,
I like to know the differences in between Enterprise Service Repository and Integration Repository (XI)?
Thanks & Regards,
Kamaljeet Singh

hi Kamaljeet,
ESR is a meta data repository, meaning that it stores data that describes other data. The meta data inside the ESR is then used by development tools, modeling tools, operational management tools, and by other services to help them do their jobs. The ESR has also been given the job of storing descriptions of business objects and models that show how services work together in process components.
Perhaps the best way to quickly understand the ESR is to list all the different types of metadata stored in in and quickly explain how that data is used.
Type of data and How it is used as follows:
Web Services Definition Language (WSDL) files These files describe the service interfaces of enterprise services and are used by development tools and during run-time to look up interface definitions.
Business Object Descriptions Business objects are used in modeling to show what structures exist in an application that are implementing services.
Process Component Models This data describes models that show how enterprise services work together to implement business processes. These models show how a service is used and what business objects implement the service.
It is important to remember that services are not implemented in the ESR. The ESR holds descriptions of services that are then implemented in applications that are separate from the repository.

How to find BADI for the enterprise service?

Hi Experts,
We are enhancing an enterprise service for Businesspartner creation by adding an additional field in the structure. But we are not able to find out the correct BADI for the enterprise service. We are using the following enterprise service - 'BusinessPartnerERPCreateRequestConfirmation_In' . I could not find any BADI in ES workplace also .How to search for a BADI for this ES.
Any help on this will be well appreciated.
Thanks in advance
Sanu

Hi Sanu.
Not all the services is an BAPI or BAPI, maybe this is an interface.
To see the related object go to esworkplace and find the service.
You will find in the page the label "Related Web Service Definition".
Copy the related value(in your case ECC_BusinessPartnerCrtRC) it and go to SAP GUI. In transaction SE84, go to enterprise service and choice service definition.
Paste the value copied in esworkplace in field Service Definition, then F8.
In the next screen double click in the returned value.
In the next screen you will see a Reference Object field. Double click in the value and you will see the related object.
In this case is an interface. You can see in Provider Class.
Hope that's help you.

Enterprise Service Outbound - SXMSPMAST Pipeline EVENT - no msg to PI triggered

Dear guys
at the moment we are trying to set up SAP enterprise services outbound in the healthcare environment, which should be used through SAP PI.
The ABAP backend is already configured to communicate with SAP PI using ABAP proxy.
We went through the documentation and set up the according customizing, hopefully we did not miss anything.
While running the mentioned report for transmitting business data via enterprise services the according proxy classes have been determined and called, logs look quite promising.
Looking at transaction sxi_monitor in ABAP provider system entries with status 110 - Event Distributed Successfully pipeline EVENT are visible, but none for pipeline SENDER, which is quite common for ABAP proxy request to SAP PI.
Configuration of Business Event
All services that are developed in Enhancement Package 5 are Point to Point enabled i.e. a service can be consumed or received directly without having any Process integration (PI). All information services (i.e. outbound services) are Business event enabled i.e. event is published when an action is performed in the system.
In order to receive the outbound information directly (i.e without Process Integration) one has to enable the Event option in the logical port configuration of the service in SOAMANAGER transaction and also check if the event in activated via SLEI_EVT_LINKAGE transaction.
According to the documentation this enterprise services could be used with or without SAP PI. So for me at the moment is not quite clear, if additional configuration is needed in SOAMANAGER or if this is only needed while working without SAP PI.
I assumption so far was it should be not necessary, and the ABAP proxy configuration already available should be used automatically to send the according request to SAP PI.
Maybe someone could give me a hint if some configuration is missing and how to get the data pushed to SAP PI.
I think the configuration is common for SAP enterprise services and not healthcare specific.
Thanks in advance,
best regards
Jochen

Dear guys
issue solved by creating logical port for proxy in transaction SOAMANAGER selection mode "PI runtime"
best regards
Jochen

Enhancing Enterprise Service - Input Message Enhancement

Hi
I am using a standard Enterprise Service and have successfully Enhanced the Output Message (Created a Data Type Enhancement in PI), did the BADI Implementation and mapped the Outgoing Response in Outbound Processing of BADI Implementation and able to get the new added fields in the Response from the Service.
Now need to understand, how to Enhance the Input Message (have gone through the Enhancement Guide) and as I understand need to Enhance the element in Inbound Processing of BADI. I can see the enhanced Data Type which I created in ESR and then Implemented the Proxy for Data Type Enhancement, nevertheless unsure what I can do with the data type in INPUT parameter/structure. As I need to map this to another Changing type parameter to be able to validate this in Outbound Processing., although I cannot create a new parameter in the Method.
Can someone guide in steps how to do Input Message enhancement - what to do I code in Inbound Processing-Method to make that available in Outbound Processing(Need to do validation based on this field to send the response back).
Thanks
Swetank

Have managed to do the same. Declared the Enhanced Input variable in public section of the class and was able to refer to the same in Outbound processing.

Which product for which Enterprise Services?

Hi,
I try to test Enterprise Services with the Netweaver Sneak Preview Edition.
On the ES Workplace there are Enterprise Services documented mainly for four categories
> mySAP ERP
> mySAP Supply Chain Management
> mySAP Supplier Relationship Management
> mySAP Customer Relationship Management
Does this imply, that these four are the products, which are required to run the respective Enterprise Services?
Only two Enterprise Services are presented for the Business Solution Maps (Human Capital Management, and Supply Chain Managemnt only for Retail).
Is it in general possible to test Enterprise Services with the NetWeaver Sneak Preview Version? I cannot download the ES Addons, since a registration for the Service Market Place is required, here.
Thank you for help,
greetings, Rafael

Each SAP Product will deliver its set of Enterprise Services and act as Service Provider. Most of them will come from mySAP ERP as it's the mostly used product in the world.
You can consume Enterprise Service from Netweaver Sneak Preview (Java or Abap) as long as you have access to one mySAP ERP system which contains Enterprise Services.

Enterprise Business Services and Oracle Service Bus

Hi,
We are using AIA and we have developed a number of EBS’. These are composite applications containing a mediator and are deployed to the SOA Server.
Am I right in saying that another option is to use the Oracle Service Bus and replace the composite application ESB’s with ESB’s in the Oracle Service Bus?
Robert

Gerhard,
I was thinking the benefits would be:
-     End point Virtualisation – Single end point for services we can configure.
-     Move the job of wiring the integrations from Development to Admin
-     Single point of monitoring for SLA’s and QOS
-     Improve visibility of ESB’s by providing a single list. (At the moment they are amongst many services in enterprise manager.)
At the moment we have 3 SOA servers connected to 6 systems. (Dev, Test and Prod) I was imagining it might be possible to have a single OSB with Service routing controlled by policies. This way we would not need three OSB setup’s.
I am also charged with planning for the development of further services and we already have a long list of composites in enterprise manager. I am imagining that this will quickly become unmanageable. With OSB we could hide the downstream services and only show the EBS’.
I also imagined that when we introduced a 11.1.1.6 SOA server we could simply adjust the routing rules at the OSB to set up a dev environment. Test out the new services work, then make similar adjustments on a per EBS basis until we have migrated completely to 11.1.1.6.
I agree that there are a lot of trade off’s and I do not really have the experience to weigh up the balance between the two. Yesterday I was asked to come up with methods of monitoring performance of the current integration as well as future integrations and the OSB data sheet talks a little bit about this which is why I am thinking more about it; Although have only got as far as looking at the OSB data sheet and some manuals.
I guess another option would be to go with some EBS’s as mediators and others on OSB but I think using a consistent method for EBS’s would be preferable.
Also there is the question do we have one OSB for all systems or separate OSB’s for Dev, Test and Prod.
