Question sixteen. What Is Sap Pi?
Answer :
Process Integration is an Integral a part of SAP Net weaver.The goal of PI is to integrate extraordinary versions of both SAP and non-SAP systems implemented on exceptional flat forms (Java, ABAP, and so forth). PI allows you to implement cross-machine enterprise procedures.PI is based on an open structure, uses open standards and offers services that are vital in a heterogeneous and complicated
system panorama: namely a runtime infrastructure for message change, configuration alternatives for dealing with business methods and message float, and options for transforming message contents among the sender and receiver systems.
The application-particular contents are transferred from the sender to the receiver in a freely defined XML schema (XML: prolonged Markup Language) using the Integration Engine. The structure of a message is consequently decided via the interface information structures used.
The imperative idea is that, throughout the design section, all interfaces required are first of all evolved independently of a platform and made available inside the shape of a WSDL description (WSDL: Web Service Description Language). Using this description you could, as an instance, outline mappings between interfaces without this having an effect on an current gadget landscape. All layout phase records is stored in the Integration Repository to be applied later in a specific system panorama. In this second phase, the configuration phase, you could pick components, interfaces, and mappings stored in the Integration Repository that are suitable on your machine panorama and business methods, and assign them to each different in logical routing. The facts due to this configuration system is stored inside the Integration Directory and you may call and examine it from the runtime of the PI.
Features:
PI allows you to do the following:- Develop pass-gadget packages. You can change multiple system messages using the runtime infrastructure and synchronous or asynchronous communique. You can either broaden new and platform
-impartial interfaces, or connect with current interfaces at runtime, the use of adapters.
Adjust message values and structures for the receiver, the usage of mappings.
- Centrally keep the message glide between logical structures in the gadget landscape, the usage of logical routing.- Connect the logical receiver to a technical gadget, the usage of Services; this system can effortlessly be switched the use of this abstraction stage (technical routing). Describe your system landscape as the idea for the description of your cross-device commercial enterprise process.

Question 35. Types Of Usefull Node Functions?
Answer :
removeContext, splitByValue, collapseContext, Copy price, createIf, exits, useOneAsMany
1.RemoveContexts: "There is genuinely no distinction between my children or grand kids or amazing grand kids". Material Group is sent in the object node of the source idoc however I want it in the header node of the goal idoc. So I need to idiot the mapping runtime that Material Group is coming inside the header node of the supply. RemoveContext exactly does that.
2.SplitByValue: "I need a one-of-a-kind determine for every instance of me"
I will try and explain the function with the equal mapping as readers can correlate well. Each instance of Itemno inside the supply structure need to generate a target itemNo and item underneath a different example of the header node within the goal. As we are able to study that occurrences of item inside the supply an target shape are distinct we cannot map the elements of the item node immediately. We use splitbyValue to obtain the same.
3.CollapseContexts: " There is just a mild distinction between my kids or grand children or fantastic grand youngsters". Similar to removeContext however context alternate is replaced with "". If we need to create empty tags within the goal for every context alternate within the supply we are able to use it. I did not find it useful so I do not want to provide an explanation for in element.
4 copyValue: "How many ever instances I occur I am copied just once". This isn't always a node feature but I am explaining it as it is used very frequently in actual-time.
Let us take an example of cloth group, which could occur as commonly as the object node. But because we're mapping it to the header in the goal node I simply want to replicate the first occurrence of material institution and map it to the header node. CopyValue precisely does that.
5.Createif: "I even have a standards for current". It is used whilst you want to create target node or detail based totally on a few circumstance.
Question 36. Differences Between Proxies And Adapters?
