What is the difference between RFC and BAPI in SAP?

The main difference between RFC and BAPI in SAP is that RFC is a mechanism that allows business applications to communicate with other systems whereas BAPI is a programming interface for business object models in SAP products.

SAP is enterprise resource planning (ERP) software. It integrates the main business functions of an organization. Business processes in SAP ERP are operations such as sales, material management, production planning, logistics, etc., finance such as financial accounting, management accounting, human capital management, and corporate services. Also, there are many modules available in SAP. Some of them include ABAP, Basic, PP, HR, etc. RFC and BAPI are two terms related to SAP.

What is RFC?

RFC stands for Remote Function Call . It is a method that allows a business application to exchange information with multiple systems. In addition, it is a SAP protocol to establish communication between systems. A function on one machine can call a function on another machine using RFCs. It is also possible to call a function in a different program on the same machine using RFCs. But, this mechanism is usually used to call functions running on a different machine. The RFC interface helps to configure the RFC connection between multiple SAP systems or a SAP and non-SAP system.

RFC provides a number of benefits for developers. Avoid developing modules over and over again on remote systems. Also, it triggers certain routines to start communication with the remote system and handles errors that occur in communication.

What is BAPI?

BAPI stands for Business Application Programming Interface . It is a standardized programming interface for business object models in SAP products. Additionally, it wraps the internal layers of the SAP business object model to confirm that all business logic, authorization, and validation are executed correctly when accessing or changing business objects.

The BOR (Business Object Repository) defines BAPIs as methods of SAP business object types that can perform business functions. Also, BAPI functions suitable for most SAP business objects are called standardized BAPIs. Some of them are the following.

BAPIs for reading data – GetList(), GetDetail(), GetStatus(), ExistenceCheck()

BAPIs for bulk processing – ChangeMultiple(), CreateMultiple(), DeleteMultiple().

Difference 

Definition

RFC is the SAP standard interface for communication between SAP systems, while BAPI is a standard programming interface that allows external applications to access business processes and data in the R/3 system.

Long way

While RFC stands for Remote Function Call, BAPI stands for Business Application Programming Interface.

Use

RFC allows you to call function modules that reside on different machines. In contrast, BAPI allows SAP functions to be accessed through formal, stable, dialog-free interfaces. So, this is another difference between RFC and BAPI in SAP.

conclusion

The main difference between RFC and BAPI in SAP is that RFC is a mechanism that allows business applications to communicate with other systems, while BAPI is a programming interface for business object models in SAP products. RFC and BAPI are two terms related to SAP.
