Hi,

BAPIs : A nice way to work with your data without learning the SAP data model. BAPIs are functions that are "published" by SAP for customer use. They are very well documented and bring less surprises than internal functions. Go to transaction BAPI to get the tree of the functions by functional areas. In addition to simply using them for data extracts or updates you can look into their source code to understand how the data is organized (but this is not an easy task). BAPIs are the first thing to check if you need to update the data (the next thing would probably be BDC - described in Knowledge Corner as well). Using BAPIs for updates can speed up your program significantly (like 100 times!). You can use them to select the data, but of course if you know how to access the database directly, simple select will work faster. Sometimes BAPIs are the only way to get the data, as it is the case with accessing some objects in APO (that are stored only in "Livecache" memory).

HI,

Programming a BAPI consists of some tasks like:

• Defining BAPI Data structures ( using SE11 )

• Creating BAPI Function Modules (For each method)

• Defining BAPI Methods in the BOR

• Generate and release

1. Defining BAPI Data structures: This is the basic step followed while creating BAPIs. All the relevant structures that are required for BAPI have to be created using T-Code SE11. The structures can be created for Import/Tables parameters.

2. Creating BAPI Function Modules: We must create new function group for each BAPI. If the BAPIs are related then the same can be grouped under the same FUNCTION GROUP to enable the sharing of global data amongst the related BAPIs.

3. Defining BAPI Methods in the BOR: When creating a new object type in BOR (Business Object Repository), there can be two possibilities. Either it is created as a subtype of an existing business object or it is created as a new business object from scratch. Create a business object using the T-Code SWO1. The business object gets created with the standard interface that contains an Interface IFSAP, an Attribute ObjectType, and two methods namely ExistenceCheck and Display. All these cannot be changed. You can add a method to the business object. For this, we will choose from the menu path, Utillities -> API methods -> Add method. To use the business object Object type status has to be set to Implemented.

4. Generate and Release: Go to SE37 and release the API enabled Function module. In the Object created in the BOR, set the status of Object Type Component to Released.

You can then display the BAPI in the BAPI Explorer. Invoke the same using the T-code BAPI.

Also have a look at below links.

Hi Kannan,

BAPI stands for Business API(Application Program Interface).

I have answered this question before..

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.

Example Code

U need to give the step_nr, item_nr, cond_count and cond_type so the correct conditon will be updated. If no condition exists for the given parameters, a new condition will be created.

U can find these parameters for a particular condition type in table KONV.

Bdc to Bapi

The steps to be followed are :

1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).

[for VA01 use BAPI_SALESORDER_CREATEFROMDAT2]

2. Create a Z program and call the BAPi (same as a Funtion module call).

2. Now, if you see this BAPi, it has

-> Importing structures.

eg: SALESDOCUMENT: this will take the Sales order header data as input.

-> Tables parameters:

eg: ORDER_ITEM_IN: this will take the line item data as input.

Note :

Only specify fields that should be changed

Select these fields by entering an X in the checkboxes

Enter a U in the UPDATEFLAG field

Always specify key fields when changing the data, including in the checkboxes

The configuration is an exception here. If this needs to be changed, you need to complete it again fully.

Maintain quantities and dates in the schedule line data

Possible UPDATEFLAGS:

U = change

D = delete

I = add

Example

1. Delete the whole order

2. Delete order items

3. Change the order

4. Change the configuration

Notes

1. Minimum entry:

You must enter the order number in the SALESDOCUMENT structure.

You must always enter key fields for changes.

You must always specify the update indicator in the ORDER_HEADER_INX.

2. Commit control:

The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.

For further details... refer to the Function Module documentation for the BAPi.

Bapi to VB(Visual Basic)

Long back I had used the following flow structure to acheive the same.

Report -> SM59 RFC destination -> COM4ABAP -> VB.exe

my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.

You need to have com4abap.exe

If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.

else refer OSS note 419822 for installation of com4abap

after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.

for setting up com4abap and rfc destination please refer to the documentation for com4abap.

Invoke NEW DCOM session

call function 'BEGIN_COM_SESSION'

exporting

service_dest = service_dest "(this will be a RFC destination created in SM59)

importing

worker_dest = worker_dest

exceptions

connect_to_dcom_service_failed = 1

connect_to_dcom_worker_failed = 2

others = 3.

call function 'create_com_instance' destination worker_dest

exporting

clsid = g_c_clsid

typelib = g_c_typelib

importing

instid = g_f_oid

exceptions

communication_failure = 1 message g_f_msg

system_failure = 2 message g_f_msg

invalid_instance_id = 3

others = 4.

call function 'com_invoke' destination worker_dest

exporting

%instid = g_f_oid

%method = 'UpdatePDF'

sntemp = g_v_const_filent

snsysid = sy-sysid

snflag = 'N'

tables

rssaptable = g_t_pdfdetail1

%return = g_t_pdfdetail1 "t_test

exceptions

communication_failure = 1 message g_f_msg

system_failure = 2 message g_f_msg

invalid_instance_id = 3

others = 4.

then close the com session , using

FM delete_com_instance

FM END_COM_SESSION

Hi Kannan Nataraj,

After reading primary information about BAPI you can run BAPI function module for example BAPI_PO_GET_DETAILS

for better understanding abt the BAPI functional modules

Hope this information would help u,
