Why web service is used?
Web services allow different organizations or applications from multiple sources to communicate without the need to share sensitive data or IT infrastructure. Instead, all information is shared through a programmatic interface across a network.
What are two types of web service?
Generally, there are two types of web services as follows: Soap Web Services. RESTful Web Services.
Is API a web service?
Though APIs and web services can both facilitate data transfers between applications over the internet, they are not the same, and the terms should not be used interchangeably in every case. The key distinction is that web services are a type of API: All web services are APIs, but not all APIs are web services.
Is REST API a web service?
Overview. A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.

What is web service?
Web Services are a standardized way of communication between a client application which consumes e.g. information from a server application in service-oriented architectures. SAP NetWeaver Application Server ABAP can be used both as a provider and a consumer of Web services. You can create, configure, publish, and consume services.
Why is communication using web services needed to be monitored for errors and performance issues?
The communication using web services needs to be monitored for errors and performance issues to ensure a smooth information flow.
What is an ABAP message?
Web Service Messages (ABAP): Web Service messages collected from SRT_UTIL → Message Monitor. Can be collected for ABAP systems.
What is web service?
Web Services are based on the client server interaction model which means two machines namely a client machine ( known as a service requestor, hereinafter “Requestor” ) and a server machine ( known as a service provider, hereinafter “Provider” ) are interacting with one another with the Requestor initiating the communication ( by issuing a request ) and the Provider machine finalizing the communication ( by issuing a response ).
What type of service interface is used to send a message to a PI?
Remember PI is exposing itself as the Provider. Therefore from the Requestor’s perspective, to send a message to PI requires the utilization of an Outbound Service Interface ( Sender’s use Outbound Interfaces ). Note Figure 5 below:
What is SOAP in XML?
SOAP is the content based format that both the Requester and Provider use to communicate with one another. SOAP is basically a standardized XML set of tags describing the content of messages being sent between the client and the server. Let’s say a sales order is being sent between the Requestor and the Provider.
What is PI in Rana?
Figure 2 above is borrowed form Rana’s tutorial. PI ( the runtime identification of which is referred to as the “Integration Engine” in the above graphic ) is considered to be a message based “Integration Broker” because it sits in between the system sending the message (hereinafter “Sender” ) and the system receiving the message ( hereinafter “Receiver” ) and performs certain tasks on behalf of both to insure the messages are both processed and transferred successfully between the two thus ensuring a smooth running integration process that a customer could design and implement. Our sales order mentioned above could be a message that PI processes for example.
What does the field in message type represent?
Note the fields contained in the message type in Figure 4. They represent the business data of the message ( in this case information about a material master record ) and will be present in the SOAP Body ( as discussed earlier ).
Does PI require a sender agreement?
We’re getting close to the goal line now. PI doesn’t always require a “Sender Agreement” to receive a message but in this case one is required. Note Figures 12 through 14 below.
Why do we need SAP PI?
Why do we need SAP PI Apart from Legacy Systems, in a large business establishment, SAP ERP does not consist of a single system but several integrated systems i.e. CRM, SRM and FICO etc. To handle with such complexities SAP introduced Process Integration a platform to provide a single point of integration for all systems without touching existing complex network of legacy systems. This is a powerful middleware by SAP to provide seamless end to end integration between SAP and non-SAP applications inside and outside the corporate boundary. SAP PI supports B2B as well as A2A exchanges, supports synchronous and asynchronous message exchange and includes built in engine for designing and executing Integration Processes.
What is the source system of a PI?
The source system is known as the sender system and the target system is known as the receiver system. The PI is not a single component, but rather a collection of components that work together flexibly to implement integration scenarios.
What is SAP ERP?
Enterprise Resource Planning i.e. ERP is an effective approach that most businesses implement to enhance their productivity and performance. SAP ERP is SAP AG’s Enterprise Resource Planning, an integrated software solution that incorporates the key business functions of the organization. The basic functionalities i.e. HR, MM, SD, FICO etc are called business modules in SAP. SAP builds them as products and sells them in the market. There are two more modules which do not support business functions directly but are utilized for presentation and integration. The former is called EP (Enterprise Portal) and the latter is called PI (Process Integration). All the business modules are developed in ABAP while EP and PI are developed mostly in Java. These modules are not executables but they need to be deployed in an Application Server i.e. ABAP Web Application Server for ABAP modules and Java Web Application Servers for Java modules.
What is integration server?
Integration Server is the central processing engine of the SAP PI. All messages are processed here in a consistent way. It consists of three separate engines
What does SAP stand for?
SAP stands for Systems, Applications, and Products in Data Processing. SAP AG is a German multinational software corporation that makes enterprise software to manage business operations and customer relations.
What is the business process engine?
The Business Process Engine is responsible for executing and persisting integration processes.
Is PI built on the same platform?
When PI was first released, not all components were built on the same platform. Integration Engine and Business Process Engine was built in ABAP while Adapter Engine, Integration Builder, SL, CM and Mapping Runtime were built in Java. So PI needs both the Java and the ABAP environment to run and is known as the dual stack.
2. Import RFC to SAP PI
Right click on RFC under imported objects under software component and provide application server/system number/user credential. Then find the RFC from the list.
6. Create outbound service interface
This should be a outbound synchronous interface with SOAP request and response message types.
11. Publish the interface under service registry
