How are BAPI's related to Conversions

Former Member · ‎2007 Aug 13

Hi friends,

I am new to BAPI's. I wonder how BAPI's are related to conversions? If anyone of you could please help me regarding this it would be helpful to me.

Thanks,

Haritha.

BAPI (Business Application Programming Interface) is a set of interfaces to object-oriented programming methods that enable a programmer to integrate third-party software into the proprietary R/3 product from SAP. For specific business tasks such as uploading transactional data, BAPIs are implemented and stored in the R/3 system as remote function call (RFC) modules.

Hence conversion related!

Hi Srinivas,

Thanks for the reply.

From the legacy system itself, do we call BAPI, which does the conversion?. How is BAPI bettter than BDC or Call Transaction?

Thanks,

Haritha

No, regarding the subject, generally you call BAPI from an ABAP program which previously loads legacy data to memory, and converts it to BAPI parameters structures.

However, BAPIs CAN be used from external systems also.

It's better than BDC in that in the future any transaction screen may change, and your program stops working.

With BAPI's, SAP assures you that the interface will remain the same so no need to adapt program.

SAP recommends using BAPIs over BDC method whenever possible.

Hi Haritha,

what is BAPI?

BAPI stands for Business API(Application Program Interface).

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.

The following standardized BAPIs are provided:

Reading instances of SAP business objects

GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.

The BAPI GetList() is a class method.

GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type

The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.

Create( ) and CreateFromData! ( )

The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.

Change( )

The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.

Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.

The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.

Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.

Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

Business application Prograaming Interface is nothing but the Method of a Business object.
