  • Develop Custom Adapters: You can use adapter SDK to develop custom adapters for extra connectivity requirements.
  • Access Public APIs: You can customize the SAP cloud integration access with public OData APIs. 

5. Briefly explain the SAP CPI architecture.

The SAP CPI architecture comes with two integration nodes, such as runtime node and tenant management. Basically, the runtime node features the Java Virtual Machine (JVM) and inflows run throughout the JVM node. It regulates the audit log and processes messages. Most frequently, it interacts with external systems through the load balancer. 

On the other hand, the tenant management nodes help read the data and manage the runtime node that the runtime node is liable for writing. This node offers a front-end editor to developers and administrators performing a variety of tasks, like user creation and role management. Moreover, it acts as an agent between varying runtime parts of human users and CPI. 

6. What do you know about the sorting or filter concept in CPI?

SAP CPI filters can be used to extract information or data from an incoming message. Through the CPI filter, you can keep just the necessary data or information. For effective filtering of information, you will need profound knowledge of XML. 

However, there is another method of filtering the information in SAP CPI as well, which is through message mapping filtering. There is also groovy mapping that helps perform complex and advanced filtering. In CPI, sorting is not an inbuilt concept. Thus, you will have to rely on custom solutions for it. 

7. What are the integration services that CPI offers?

The SAP CPI offers a variety of integration services. For example, it provides Application Programming Interface (API) management that assists in managing the API, assessing the use of API, and limiting API access. 

CPI provides connectivity as it assists in connecting the on-premise application with the CPI interface. Apart from this, it also provides process integration that is extensively used by SAP consultants. It helps in developing and exchanging information through varying connectivity adapters. Lastly, SAP CPI also provides an API business hub that helps in publishing custom APIs in the business hub. 

8. What integration scenarios can you build through SAP CPI?

The diverse integration scenarios that you can develop through SAP CPI are cloud-to-cloud integration and on-premise-to-cloud integration. While the former helps in connecting diverse cloud applications, the latter helps in connecting on-premise systems and cloud apps. 

9. Differentiate between Neo and Cloud Foundry?

Here are some differences between neo and cloud foundry:

  • The primary difference between neo and cloud foundry is that the latter comprises an open-source runtime and the former comprises SAP proprietary runtime. 
  • Moreover, the cloud foundry environment is supportive of Bring Your On Language concept and the neo environment does not support that. 
  • Another major difference between the two is that the cloud foundry is supportive of multiple data centers, like GCP, Azure, and AWS while neo only supports SAP data centers. 

10. What are the SAP pre-built adapters used for?

SAP provides a set of prebuilt adapters with CPI, which can be used for the following:

  • Synchronous and asynchronous data integration
  • Application-to-application (A2A) integration
  • Business-to-business (B2B) integration
  • Data source and applications integration between cloud and non-premise apps
  • Data source and applications integration between non-SAP and SAP systems

23. Define pooled tables in SAP.

A pooled table is a specialized table available in the SAP Advanced Business Application Programming (ABAP) dictionary and is used to store control data. It is an SAP proprietary creation and has many-to-one relations with tables in the SAP database. This simply means that for a given pooled table in a database, the SAP data dictionary can have several small tables. SAP will be using pooled tables to hold and integrate a large number of small tables. This, in turn, helps in decreasing the resources and space needed at the database level. Mainly, SAP uses pooled tables for system data maintenance. 

24. What do you know about SAP R/3?

While SAP R/3 can be used by any company, it still varies in terms of operations. There are three primary layers in SAP R/3, such as:

  • Presentation Layer: It comprises software components made of SAPgui (Graphical User Interface). This layer is liable for sending the input of users to the application server and for receiving the data to be showcased.   
  • Application Layer: It comprises multiple or single application servers along with a message server. This message server helps transmit requests from one application server to the other in a system. Alongside this, it holds information related to application server groups and the current load balancing. It uses the information to assign an accurate server when someone logs into the system.
  • Database Layer: This one comprises a central database system with every data in the R/3 system. SAP has come up with its own database, which is named HANA and it is compatible with several other databases as well. 

25. What is the difference between Native SQL and Open SQL?

Here is the difference between Native SQL and Open SQL:

Native SQL

Open SQL

It consists of database-specific SQL statements. 

It consists ABAP specific SQL statements. 

Native SQL can be used on such database tables that the ABAP dictionary is not administering. 

Open SQL can only operate on such database tables that were created in the ABAP dictionary. 

It doesn’t support table buffering in the SAP application server. 

It supports table buffering in the SAP application server. 

It is not supportive of conjunction with ABAP construction. 

It supports conjunction with ABAP construction.
