SAP BAPI
What is BAPI in SAP: SAP BAPI (Business Application Programming Interface) — A standard interface of the business object models in SAP R/3.
Most of the time, BAPIs are how customer code and third-party applications deal with SAP products. Transnational BAPIs encapsulate the intermediary SAP business object model-layer to ensure that any appropriate business logic, validations or authorization checks are done when we reference a prefix which has been written via your program.
How BAPI works
Implementing them as function modules with API to SAP internal is called BAPI. They could be implemented calling business object models defined using the Business Objects Processing Framework (BOPF), or legacy models defined with programs, tables and function modules.
BAPI Meaning ; BAPIs are standardized interfaces that enable communication between SAP systems and external applications. They are used to perform various business functions, such as creating, updating, or retrieving data from an SAP system
Some Important Features about BAPI
Some of the important points related to SAP BAPI:Â
1) SAP BAPI mustn’t contain call transaction.
2) BAPI mustn’t invoke commit work instead of commit work. We call the BAPI-TRANSACTION_COMMIT function module.
3) BAPI structure mustn’t contains includes.
4) There is o functional dependences between any two BAPI’s.
5) BAPI never calls to terminate the program.
Whenever an error occurred in BAPI it written those errors through written parameter.
6) BAPI must not contain dialogue programs.
7) BAPI mustn’t contain Submit reports.
Steps to create our own custom BAPI:
Best way to learn SAP BAPI Tutorial with complete steps
1. Create the BAPI structure (SE11)
2. Create the BAPI function module (SE37)
1. Which is remote enable.
2. Must contains RETURN parameter
3. All parameters are pass by value
3. Create the object and methods for BAPI function module (SW01)
4. Release the object and method (SW01).
Object: Develop a custom BAPIs to display the purchasing doc number, doc date & vendor number based on the given purchasing doc number.
Steps to create the BAPIs structure:
-> Execute SE11.
-> Select the radio button data type.
-> Provide the BAPI structure name (ZBAPI_STR).
-> Click on create.
-> Select the radio button structure. Enter.
-> Provide short description (BAPI Structure).
-> Provide the component & component type.
EBELN EBELN
BEDAT BEDAT
LIFNR LIFNR
-> Save in own package. Check, activate.
Steps to create function group:
-> Execute SE37.
-> In the menu bar click on goto -> function groups -> create group.
-> Provide the function group name (ZBAPI_FG), short description.
-> Save in our own package.
Steps to activate the function group:
-> In the menu bar click on environment -> inactive objects.
-> Expand the function group under transportable objects.
-> Select the function group. Right click -> activate. Enter.
Steps to create function module:Â
Import
Source code :
Select single ebeln bedat lifnr from ekko into wa_ekko where ebeln = i_ebeln.
-> Save, check, activate.
-> Click on back. In the menu bar click on function module. Release -> Release.
-> Function module is released.
Steps to release the object & method for BAPI function module:
-> Execute SW01.
-> Provide the object name (ZBAPI_OB).
-> Click on create.
-> Provide the same to all. Select the application (M). Enter.
-> Click on enter. Save in our package.
-> Place the cursor on methods. In the menu bar click on utilities. API methods -> Add method.
-> Provide function module name (ZBAPI_FM1). Click on enter.
-> Click on next step (CTRL + SHIFT + F11). Click on next.
-> Click on yes. Click on save.
Steps to release the object & method:
-> Place the cursor on object (ZBAPI_7OB).
-> In the menu bar click on edit -> change release status -> object type ïƒ to modeled
(to implemented, to release also).
-> Select the method. In the menu bar, click on edit -> change release status -> object type component-> to modeled (to implemented, to released also).
-> Click on generate (CTRL + F3).
Steps to check BAPI in SAP is available or not in BOR:
-> Execute BAPI transaction.
Click on alphabetical tab & Observe our BAPI.
Steps to identify the standard BAPIs:
Method 1:
-> Execute ‘SE93’.
-> Provide the related transaction code (ME23N).
-> Click on display.
-> Click on display object list (CTRL + SHIFT + F5) in the application tool bar.
-> Expand the package.
-> Expand the business engineering.
-> Expand the business object types.
-> Double click on our required business object.
-> Expand the method. Double click on our required method (Get details).
-> Click on ABAP tab.
-> Identify the BAPI name (BAPI_PO_GETDETAIL).
Method 2:
By using BAPI methods, we can identify the standard BAPI. Some of the BAPI methods are
1. Get list ()
2. Get details ()
3. Get status ()
4. Existence check ()
5. Create ()
6. Change ()
7. Delete ()
Steps to identify the BAPI based on BAPI method name:
-> Execute ‘SE37’.
-> Provide BAPI *<Method name>. Click on F4.
-> We get the list of BAPIs related to that method & identify our required method.
Note: -When ever we are working with crate, change, delete BAPIs, then we must committed the data base by using ‘BAPI_TRANSACTION_COMMIT’ function module. Other wise the data base isn’t updated.
Steps to create the bank details manually:
-> Execute ‘FI01’.
-> Provide bank country key (IN).
-> Bank key (121516). Enter.
-> Provide the bank name (HDFC Bank).
-> Save.

ex: GETLIST( ) bapi’s are called instance independent bapi
2.Instance dependent bapi : For which bapi’s, we must provide the input than BAPI’s are called instance dependent BAPI

Difference between RFC and BAPI
The main difference between BAPI and RFC is , RFC is used to enable communication between different systems or applications, while BAPI is used to provide a standardized way of accessing and manipulating business object
it is a common SAP BAPI interview questions.Â
Note: -BAPI is used to connecting from SAP to SAP as well as SAP to NON – SAP. Where as RFC is used to connecting from SAP-SAP only.

Differences between BAPI and BDC
How to find BAPI in SAP ABAP
Go to Transaction SE37 This is the tcode which is used to display or manage Function Module.
-> Next Search for BAPIs: Basically in in Function Module enter search term as per your need in BAPIs related like BAPI_NETWORK. Then Press F4 to get a list of function modules .
Here are some specific BAPIs and function modules related to network creation and maintenance:
BAPI_NETWORK_MAINTAIN: Used for maintaining network data.
2002_NETWORK_CREATE: A function module for creating networks.
NETWORK_CREATE: Another function module for creating networks.
NETWORK_ENJOY_CREATE: A user-friendly function module for creating networks.
CNPB_M_NETWORK_CREATE: A function module for creating networks, possibly with additional features or specific use cases.

RFC in SAP ABAP
RFC stands for Remote Function Call, which is a way to execute functions or methods on a remote SAP system. This allows for seamless integration and communication between different SAP systems.
