Hi,

What are the advantages of BAPI?

Hi anu,

1. Simple to use (its just an FM)

2. Not cumbersome like bdc

where we have to record each and every screen

sequence.

3. SAP guarantees the consistency

of bapi in future releases.

Hi,

One of the big plusses for BAPIs is that the interface and function are not supposed to change. This is a big plus when you do upgrades or hot packs because the transaction can change (format, required inputs etc) which means you then need to update the call transaction.

Some of the BAPIs are better documented and easier to use than others.

You usually need to perform the BAPI that actually does the COMMIT after you call your BAPI.

The Program coding for calling a BAPI is usually cleaner than setting up the screen flow etc for the Call Transaction.

You don't need to worry about special data circumstances interrupting the normal data flow of the screens and causing errors because of that.

BAPIs probably have better performance since they don't do the screen flow processing.

In general if the BAPI exists for the transaction you want to perform and you can figure out how to use it the BAPI is probably the best way to go.

This is just from my experience working with both BAPI and Call Transaction. I have had some very good successes with BAPIs, but very occasionally found that I could not get the BAPI to perform the update I needed.

Refer the transaction BAPI for detail information.

hello...

You calla BAPI exactly the same way you call a Function Module. What BAPI are you interested in using?

Also if you search the SDN forum on your specific BAPI you will find heaps of examples. Also never underestimate the power of Google (I have found many sample programs that way!).

BDC = Batch Data Commands

Comparable to macros in, e. g., Word. You enter data in a SAP standard transaction while recording it. This recording can be turned into an ABAP program or function module. You can modify these programs to change, e. g., the static data that you enteren in the recording to dynamic data that is read from a file or something like that.

Works best with "simple" transactions, espacially the newer "Enjoy" transactions aren't easy to implement.

Not recommended by SAP any more, although it can be simple and effective to use sometimes.

Works with single or multiple transactions (hence "Batch").

BAPI = Business Application Programming Interface.

From an ABAP programmer's perspective a BAPI is simply a certain type of RFC-enabled function module that obeys certain rules such as: No explicit COMMIT WORK in the FM, return a BAPIRETxxx message, no user interaction, etc. See the documentation for details.

Recommended and supported way for management of many SAP business objects. Many different objects and methods available, although not everything a programmer needs.

Synchronous function modules, generally only one business object per call.

Hope that helps (please reward me if it does ,

Programming is very easy using badis.

The labor of coding for the bdcs especially using table controls is very easy in bapi's as it is not dependent upon the screen flow of the transaction .

Hi Anu,

BAPIs are RFC enabled function modules. The advantage of BAPIs over RFCs is that they are used for business objects.

You can create Business Objects using transaction swo1.

Hai Anu Raadha

Go through the following Document

BAPI_CUSTOMER_CREATEFROMDATA

BAPI_CUSTOMER_CREATEFROMDATA1

Or you can use FM SD_CUSTOMER_MAINTAIN_ALL

what is BAPI?

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.

Java Connector(JCO) can call not only BAPI's but also the function modules which are remotely enabled..

BAPI's as i said earlier are remotely enabled function modules..

Hence, JCO can call also BAPI's(n not only BAPI's as u mentioned).

Check the following BDC over 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.

hi

1.Easy to use.Jus like normal FMs.

2.Provides an external interface to other systems thru which other systems(Non-SAP) can access the SAP Business Objects.
