Technical device represents the bodily device, it incorporates all of the physical traits of your machine for eg even as developing a Technical gadget in your R3 gadget - u specify the host name, message server, OS, the customers and so forth.

Q10. What Is The Use Of Performance Monitoring?

You use performance tracking to display statistical facts at the performance of message processing. The records comes from the Integration Server (IS) or the Process Monitoring Infrastructure (PMI).The relevant tool for performance monitoring is the Runtime Workbench, which you call from the Integration Builder start page.

Q11. Disadvantages Of Xslt Mapping?

You can not use Java APIs and Classes in it. There is probably cases on your mapping whilst you'll must carry out something like a homes document look up or a DB lookup, such scenarios aren't viable in XSLT.

Q12. Differences Between Proxies And Adapters?

Proxies are interfaces, with the intention to get carried out within the software system. They can be created best in the device from message interfaces using the proxy era features. You can use proxies for systems with WAS >=6.20.

XI will communicate in local language with SAP structures through proxies. Proxies uses XML - SOAP based totally communication for each ABAP and Java Proxies.

Adapters will convert one format into another predicted/goal format. Manner from SAP widespread codecs and as well as 3rd celebration formats to goal codecs

Q13. What Are Advanced Java Functions In Xi?

They allow to add your personal features to the message mapping.

Q14. How Idoc Is Posted To R/3 System?

XI isn't answerable for posting idocs. XI is simply responsible for populating the idoc structure with the facts. The function module associated with idoc shape is posting the real statistics into the R/3 tables.

Q15. What Is The Main Difference Between The Monitoring Done Using Sxmb_moni And The One Done Using Runtime Workbench In Xi.?

SXMB_MONI is based at the ABAP stack whilst the runtime workbench is at the JAVA stack. Moreover the runtime workbench has different features like issue monitoring, mesg. Monitoring, end-give up monitoring, alert confg. , Performance monitoring and so on.

Q23. The Information From The Software Catalog Is Used By Which Component Of The Integration Builder?

Integration Repository to arrange improvement efforts.  Software Component Version organizes all design work in the Integration Repository. This makes sense, as interfaces logically belong to a software program component and to a selected model.

Q24. What Is Business System?

Business System is a logical entity, which represents logical view of your technical device. (Eg a customer in R3 system can be represented as business device in SLD) For one technical gadget you could have multiple enterprise structures.

Q25. Types Of Usefull Node Functions?

RemoveContext, splitByValue, collapseContext, Copy value, createIf, exits, useOneAsMany

1.RemoveContexts: "There is clearly no difference among my kids or grand youngsters or extraordinary grand children". Material Group is despatched inside the item node of the supply idoc but I want it in the header node of the goal idoc. So I want to fool the mapping runtime that Material Group is coming within the header node of the source. RemoveContext precisely does that.

2.SplitByValue: "I want a special figure for each instance of me"

I will attempt to give an explanation for the function with the equal mapping as readers can correlate properly. Each example of Itemno within the source structure should generate a goal itemNo and item beneath a exceptional example of the header node inside the target. As we are able to look at that occurrences of item inside the supply an target shape are exceptional we cannot map the elements of the object node at once. We use splitbyValue to reap the same.

Three.CollapseContexts: " There is just a moderate distinction among my youngsters or grand youngsters or excellent grand youngsters". Similar to removeContext but context change is replaced with "". If we want to create empty tags inside the goal for every context exchange inside the source we can use it. I did not locate it useful so I do not want to give an explanation for in detail.

Four copyValue: "How many ever instances I occur I am copied simply as soon as". This is not a node feature but I am explaining it as it's miles used very regularly in real-time.

Let us take an example of cloth group, that may occur as often as the item node. But due to the fact that we are mapping it to the header in the goal node I simply need to replicate the first occurrence of cloth organization and map it to the header node. CopyValue exactly does that.

5.Createif: "I have a standards for present". It is used whilst you need to create goal node or detail based on some condition.

Q26. What Are The Sap Xi Components?

A) Integration Builder

b) Integration Server

c) System Land Scape Directory,

d) Runtime Work Bench.

Pre-Delivered integration content material:

(Def: -SAP solutions convey their integration Meta information like CRM, SRM, SCM, xRPM, and so forth.) As brought with the combination repository of XI

Benefit: -

A) Out-of-the-container of integration answer

B) Simplified upgrade of SAP solutions

C) Versioning and modification management of integration of Meta information.

Openness and interoperability:

(Def: -Connect to current integration solutions) like

Through JMS messaging (e.G MQ collection) and SOAP.

 Use open, XML standards for integration

 Incorporate existing functionality in to new system (Adapters (JCA),

Q32. What Is Sap Pi?

Process Integration is an Integral part of SAP Net weaver.The aim of PI is to integrate one-of-a-kind variations of both SAP and non-SAP structures applied on special flat paperwork (Java, ABAP, and so forth). PI enables you to put into effect move-gadget business strategies.PI is based on an open structure, makes use of open standards and offers offerings which are essential in a heterogeneous and complex

system panorama: particularly a runtime infrastructure for message alternate, configuration alternatives for coping with commercial enterprise strategies and message glide, and alternatives for reworking message contents between the sender and receiver systems.          

The software-precise contents are transferred from the sender to the receiver in a freely described XML schema (XML: prolonged Markup Language) using the Integration Engine. The shape of a message is consequently determined by way of the interface information structures used.

The valuable idea is that, for the duration of the design segment, all interfaces required are to start with advanced independently of a platform and made available inside the form of a WSDL description (WSDL: Web Service Description Language). Using this description you can, for example, define mappings among interfaces with out this having an effect on an existing device panorama. All layout section records is saved in the Integration Repository to be implemented later in a specific machine landscape. In this 2nd segment, the configuration phase, you may choose components, interfaces, and mappings stored in the Integration Repository which can be suitable on your gadget panorama and business strategies, and assign them to every other in logical routing. The records as a consequence of this configuration system is saved within the Integration Directory and you can call and evaluate it from the runtime of the PI.

Features:

PI allows you to do the following:- Develop pass-system packages. You can trade a couple of system messages using the runtime infrastructure and synchronous or asynchronous communique. You can both broaden new and platform

-unbiased interfaces, or connect to current interfaces at runtime, the use of adapters.

Adjust message values and systems for the receiver, the use of mappings.

- Centrally keep the message glide between logical systems in the machine landscape, using logical routing.- Connect the logical receiver to a technical device, the use of Services; this gadget can without difficulty be switched using this abstraction stage (technical routing). Describe your device panorama as the premise for the outline of your go-system enterprise manner.

Q33. What Are Routing Rules?

Receiver willpower policies and interface dedication regulations (consists of mapping assign).

Q34. What Are The 2 Main Areas Of The Sld?

The Software Catalog describes the set up merchandise and their constituent components. The Systems Catalog describes the structures inside the facts center from  perspectives.

Q35. What Are The Advantages Of Sap Xi Over Other Tools?

XI is a middleware like many others. It is properly proper for connecting SAP systems with each different and with non-SAP.If your awareness isn't always on SAP systems, different solutions might be a higher desire today. SAP XI presents an integrated workflow engine that permits to define adapters to non-XML-protocols and mappings to transform data content from source to goal.

Any completely mature middleware have to offer those three layers.

@An unbiased Message Queue

@A statistics consolidator and mapping engine

@Workflow processor.

XI is lacking full-fledged Message Queue compared to different set up Middleware products. Currently, SAP XI does now not have the capabilities like IBM Websphere, Seeburger or TIBCO.SAP's next XI launch would possibly provide this missing piece and many extra capabilities, which is due 2007 i guess. Here are the advantages of SAP XI from my factor of view. There are plenty of benefits however to list some:

* Easy Integration with SAP products & additives (RFC, IDOC, Proxy).

* Data security as anticipated from any SAP product.

* Standards based totally - XML, XSD, Xpath and so on

* Ability to talk with other messaging structures/products.

* Business Process Management

* Synchronous & Asynchronous conversation possible.

* Complex tactics for communication viable rather than handiest sending and receiving (commercial enterprise procedure management) (connect e.G. Asynchronous and synchronous steps, outline complicated communication scenarios)

* Mapping and so on feasible to perform in Java. Platform independent Java components.

* Java & .Net assist.

* Big range of adapters for distinct technology / equipment (SOAP, Mail, JDBC, CDIX...)to be had in popular or presented by using other corporations (EDI e.G. Via Seeburger).

* Process functionalities internal XI to modify content material inside the communique channel on own described regulations for commercial enterprise purposes.

* Central monitoring for data conversation for all of your communique between one-of-a-kind systems.

* And the marketing issue: SAP and its partners offer high extent of development competencies to make XI continually up-to-date for brand spanking new necessities.

Q36. What Is The Message Flow In Sap Xi?

Inbound dealing with, receiver dedication, interface determination, channel determination, mapping, outbound dealing with.

Q37. When We Use Xi Adapter?
