SAP PI Interview Questions and Answers
This technology facilitates seamless communications among systems and applications, facilitating quick data transmission, validation, and transformation processes.
1. What is SAP Process Integration?
SAP Process Integration is an Enterprise Application Integration Platform designed to facilitate the seamless fusion of SAP with non-SAP apps; PI is essential in unifying peripheral apps as it creates an orderly data path between systems.
2. What is the role of PI in integrating peripheral applications?
Its PI enables integration among peripheral applications like SAP ECC 6.0, third-party payroll solutions and mainframe applications.
3. How does PI help organisations streamline their processes, improve efficiency, and maintain a competitive edge in the market?
By meeting the challenges associated with complex customer landscapes, PI can assist organisations in streamlining processes, increasing efficiency, and retaining competitive advantages within their market environment.
4. What is PI used for?
PI can be utilised for A2A integration within an organisational landscape and B2B.
5. What is the difference between A2A and B2B integration?
A2A refers to communication among applications within one customer landscape, while B2B encompasses integration among multiple businesses.
6. What runs on the SAP Web Application Server?
SAP PI runs on the SAP Web Application Server, which is used by all components in NetWeaver and PI.
7.What is the System Landscape Directory?
PI’s System Landscape Directory provides vital information regarding all systems within its customers’ landscapes. Specifically, the technical techniques that register on it enable PI to connect and understand products/software components from these techniques based on information available within it.
8.What is the importance of the SLD?
An SLD provides customers with information regarding all systems within their landscape ECC systems, third-party apps such as SAP Portal or cloud services like SuccessFactors within which their business exists.
9.What is the enterprise services repository?
An enterprise services repository is where all design work should occur in Project Intelligence; you will define data formats and mappings between systems here.
10. What is the integration directory?
An Integration directory is the component of PI where interfaces can be configured; this represents configuration time, while an enterprise service repository acts as design time.
11. What is the integration engine?
An Integration Engine executes the main pipeline of Process Integration and any components it may include.
12. What is the purpose of monitoring in PI?
Monitoring is crucial to track messages sent between systems, for example, from SAP IDOCs being processed downstream to the downstream method or vice versa or files sent from third-party systems being received in SAP systems.
13. What is the non-central adapter engine used for?
The non-central adapter engine connects applications such as SAP systems, service providers and service consumers through integration or adapter engines.
14. What is the system landscape directory, and how can it be accessed?
A System Landscape Directory contains all systems within a landscape and is easily accessed using any browser, such as Internet Explorer, Chrome, or Firefox.

An ESR is a design environment for Process Integration that enables users to design and construct interfaces using objects like data types, message interfaces, service interfaces and scenario editors.
16.What is the difference between the ESR and the integration directory?
ESR represents the design phase, while the integration directory is the configuration time. ESR allows designers and builders to design objects while the Integration director controls how those objects will be utilised during runtime.
17.What is the role of the system landscape directory in the ESR?
The System Landscape Directory is used by ESR to access software component versions from SLD for use within it.
18. What is pre-delivered integration content?
SAP offers pre-delivered integration content, which can be imported directly into ESR for easy configuration of interfaces without building anything from scratch in PI.
19.What can be done with the integration directory?
An Integration directory allows developers of ESR objects to use them during the runtime of PI, using multiple configuration editors or wizards as desired to define how an end-to-end interface will run during the execution of runtime processes.
20.What are the different types of objects in the ESR?
ESR comprises data types, message interfaces, service interfaces, and scenario editors, each with a purpose that can be designed or built using different kinds of editors in ESR.
21. What is CCBPM?
It is a design time component used as the runtime; CCBPM helps orchestrate stateful interactions in an organised fashion through its runtime part and runtime component PI.
22.What is BPEL?
BPEL is an industry-standard language that helps users design and model interfaces; in turn, CCBPM uses this code.
23. What is the enterprise service repository?
The Enterprise Service Repository serves as the design centre of PI, where interfaces are developed and tested on the Java stack.
24. What is the integration directory?
An Integration Director is the configuration time of a PI server where individual components from an enterprise service repository can be combined into an end-to-end interface.
25.What are the three components of the integration server in PI?
PI’s integration server comprises three engines or components: an adapter engine, an integration engine and a business process engine.
26. What are the main components of PI?
At its heart lies an enterprise service bus for messaging across systems or other locations on the internet, as well as features like its platform, which works particularly well when integrated with SAP systems and has the core concept of document-based B2B trading.
27. What is the focus of the PI system?
The primary function of the PI system is to connect NetWeaver trial accounts with other strategies for application-to-application integration, business-to-business relationships, and file transfer services.
28. What is the Service-Oriented Architecture?
SOA refers to any system that allows users to plug in services, add methods, and remove others seamlessly with little need for administration and manual intervention from IT or service teams.
29. What is the difference between the dual-stack and single-stack architecture?
Dual stack architecture places configuration at the top of the system, and adapters communicate between themselves; in single stack architecture, messages are collected directly by adapters for storage within their engine.

30. What are adapters?
Adapters provide communication channels between systems; receiver receives messages from connected systems, while another distributes those to third-party systems.
31. What is an XML document?
An XML document typically comprises a declaration, UTF-8 encoding, and an order tag that organises its structure and attributes, such as headings, date formats, line numbers, and content currency.
32.What is mapping in the SAP system?
Mapping refers to translating one format to another, something for which the Pi system was specifically developed.
Integration between these systems is possible as each wants to send their message out in their preferred manner and receive it on their design system.
33. What is XSLT?
XSLT is an XML transformation language designed to transform documents from one format into another for structural operations or mapping elements, among other tasks.
34. What is the graphical mapping tool?
The Graphical Mapping Tool allows for mapping between documents, giving users visibility of each node’s data as they examine its context relative to other elements in a document.
35.What is the role of the PI tool page?
The PI Tool Page in a repository offers monitoring capabilities; the SLD catalogue is also helpful in tracking installed products with their software components and describes any upgrades necessary.
36. What is the purpose of SLD in PI?
SLD is an essential component in PI that allows users to design software components, products and business systems; it is used in the design and configuration area, where users can build new items and import existing ones from SLD’s SLA repository.
37. What is the integration server?
An integration server serves as the core component of Process Integration, comprising three essential parts central adapter engine, integration engine and business process engine.
38. What is the non-central adapter engine?
As with the central engine, this will be discussed further when discussing various architecture options of PI in later modules of this course.
