Top 9 Interface and Integration Methods in the SAP System

The file interface is a traditional method used to connect SAP systems with external third-party applications. It involves transferring data through text or Excel files, either by sending them to a designated directory or extracting them from the application server. This approach offers a basic and straightforward way of exchanging information between different systems.

This method involves minimal intricate programming, simplifying the process for users to use FTP/SFTP for transferring a specific file from SAP to an external system. The file is then forwarded to the SAP NetWeaver Process Integration (PI) framework where it undergoes conversion and mapping according to the requirements of the third-party system. This ensures that the file can be sent in various formats such as JSON, XML, and others as per need.

2) IDoc

Another method that can be used to enable communication between SAP and non-SAP systems is through the use of Intermediate Document (IDoc).

By utilizing the SAP Gateway feature, organizations have the ability to offer RFC interfaces and SAP ABAP functions through a REST API. This enables users to utilize the HTTP protocol for seamless and real-time data transfer between different systems and file formats.

Below are some notable distinctions between REST Web Service and SOAP APIs.

  • REST provides a lighter design and functionality
  • REST is faster than SOAP
  • REST can transform data directly into JSON or XML format
  • REST supports critical CRUD (Create, Read, Update, and Delete) operations
  • REST can operate synchronously or be set to align with system requirements
  • REST is stateless, allowing system resources to be saved

4) SOAP

SOAP offers a smart web service that enables efficient communication and data exchange between SAP and non-SAP systems. This allows companies to utilize the HTTP protocol and Web Service Description Language (WSDL) features, enhancing their communication capabilities.

SOAP APIs are commonly used in an asynchronous manner, but they can be customized to suit specific business needs. By utilizing the SOAP interface, organizations can guarantee dependable messaging (RM), which ensures that the receiving system successfully receives the message and facilitates regular data transfers between different systems.

5) Remote Function Call

The usual method for establishing connections between SAP and non-SAP systems, as well as between two different SAP systems, is through the Remote Function Call (RFC) interface. This interface utilizes the Client and Server concept to execute functions by making synchronous calls to the RFC server.
