Hi,

Technically, not much at all. They are both remote enabled functions that can be accessed from outside of SAP (to be more technically correct, from outside of the ABAP stack).

From a usage/functional perspective however, BAPIs are a little bit more special from RFCs.

Bapis:

- are designed as the methods of business objects in the business object repository (accessable using transaction BAPI or SWO1)

- have non-technical parameter names (the technical field names in SAP are mapped)

- have a fixed interface and functionality across all SAP releases (this is probably the key point as it means you can develop integrations with them which do not need to be changed when you upgrade)

Generally, if you are trying to find a function for a particular requirement you should look for a BAPI first, then for a RFC function which has a released status (check the function attributes in SE37), and then just a normal RFC last.

The benefit of an RFC function with released status means that it also has a fixed interface which will not change with new SAP releases.

See the below threads for the detailed information:

U can make it remote enabled by checking a check box which is available when u create that.

Thanks,

hi,

A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..

You can make your function module remotely enabled in attributes of Function module but

A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).

BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

To know what kind of animal a Bapi is, nothing better than the BAPI user guide site!

RFC and BAPIs are remote enabled function modules. They are practicly the same. A BAPI is one step further as it usually is a self contained business function, such as "Create Purchase Order", or "Change Sales Document". BAPIs interface is very well defined and documented. BAPIs can be found in the BAPI browser via transaction BAPI. RFCs are just remote enabled function modules.

BAPI stands for Business Application Programming Interface. It is a library of functions that are released to the public as an interface into an existing SAP system from an external system.

RFC is the protocol used to call functions in an R/3 system by a caller external to R/3 or to call programs external to R/3 from an R/3 system. Functions can only be called via RFC, if they are tagged as RFC functions in the SAP development workbench.
