What is SAP PI?SAP PI (Process Integration) is an integration platform which provides seamless integration between SAP and non-SAP applications within the organization A2A (Application to Application) or even outside the organization B2B (Business to Business). What is SAP PO?SAP Process Orchestration is a tool to automate and optimize business processes. It combines features of SAP Business Process Management (BPM), SAP Process Integration(PI) and SAP Business Rules Management(BRM). In other words, it's more advanced version of SAP PI and has all the tools required to integrate applications. Understanding SAP PI/PO with an ExampleBut this was a technical aspect of SAP PI, but to understand this better we will see the example of implementation of SAP PI.Example: To understand the concept of SAP PI more clearly, we take an example of a large-scale Dairy Industry, which is operating in a large portion of a state and dominating the region. But there is some small-scale dairy industries operating in the same region, parallel to the large-scale industry which is not making a profit due to their price variation compare to large-scale industry.
So to avoid the pricing conflict and maintaining the same price all over the region, large scale and small scale industry decide to link together, with the help of SAP PI. They interconnect with each other with the help of SAP PI and started to work as a single unit. Now, through SAP PI they are able to exchange all the information pertaining to dairy industry, including pricing and share an equal amount of profit.SAP PI connects different platforms like.
SAP and Non-SAP systems. B2B and A2A Scenarios. Asynchronous and Synchronous Communications. Cross-component business process managementIn this training, we will learn.Why SAP PI/PO?Prior to SAP PI, business would connect with each other through point-to-point communication. But this process is not used for multiple and complex processes. For smooth communication between multiple businesses, Mediated communication or Integration broker is used, and SAP PI adapts this system very well.
It enables interconnection of a different process via a central location known as Integration Broker, unlike the point to point connection which is more like a spider web. The integration broker or server is an integral part of mediated communication consist of based Advanced Adapter Engine (AAE) and an integration engine for routing.
Mediated communication is based on an integration broker which is executed by exchanging XML messages.SAP PI OverviewLet see how SAP PI handles the XML messages by the help of Integration Broker. Communicate: It can translate files into any format whether an internal file format or any business to business integration standard.SAP PI/PO ArchitectureSAP PI is not a single component responsible for the integration of SAP and Non- SAP application, but it is a cluster of components that together make SAP PI functional. This architecture of SAP PI or components is used during design time, configuration time and at run time. The various components of SAP PI include.
System Landscape Directory: It is a central information provider in a system landscape. SLD contains two types of information, 'Component Information (Installable & Installed) and Landscape description.'
. Integration Builder: It is a tool-set which contains a set of tools for accessing and editing integration objects.
Integration Repository: To develop, design and maintain data types, message structures, mappings, interfaces, integration processes and integration scenarios independently of system landscape, integration repository is used. Integration Server: It is a central processing engine of the PI. All messages are processed using this server. Central Monitoring: With the help of this monitoring of PI domain is done, and 'workbench' is the tool that is used for monitoring.
Adapter Engine: It acts as a connector to connect the integration engine to SAP systems and other systems. Message Processing Technique by PI: To access data from SAP and Non-SAP application this technique is used.
SAP PI uses an intermediate document like IDoc to Flat files to transfer their data. Design: Process Integration (PI) uses integration repository to design message structure. Configuration: Integration Directory (ID) is used to configure technical parameters for objects created in IR ( Integration Repository).
Message Processing: Once the IDOC is activated in SAP system, PI takes in charge and convert messages into XML format for its internal processing. Message Monitoring: The messages can be monitored and traced using 'Run Time Workbench'. This tool can be useful in monitoring sender and receiver adapters, Outgoing and Incoming messages, End to End monitoring of complete scenario and error traces.Connectivity: Proxy Framework & Adapter Framework Adapter Framework:SAP PI connects with any external systems (SAP or Non-SAP) using the Adapter Framework. The adapter framework is based on the AS Java runtime environment and the connector architecture (JCA) version. The data is received from the wire through a receive location that is listening for messages at certain protocol at a specified address.
After the message is received by the receive location, a message is sent to the adapter. It creates a new BizTalk message, attaches the data stream to the message. It adds any meta-data pertaining to the end-point over which the data was received and then the message is submitted to the message engine. Message engine sends the message to the receive pipeline where the data is transformed into XML, here the message sender is authenticated, a message is decrypted and the XML is validated. Next, the messaging engine published the message to the message box.
The message box is a Microsofttable containing messages to be processed. The messaging engine sends the message to either the orchestration or send port.SAP PI/PO SecurityFor messages, SAP PI provides the message level security for XI message protocol, for the SOAP adapter, for the RosettaNet protocol, for mail adapter, for the CIDX protocol and for connectivity with WSRM (Web Service Reliable Messaging) enabled systems. In SAP PI message level security enabled through the use of encryption, digital signature, SAML Assertion, Username token, Certificate token, etc.
