Hi,

BAPI stands for Business Application Programming Interface. It 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.

There are 5 different steps in BAPI.

- Create BAPI Structure

- Create BAPI Function Module or API Method.

- Create BAPI object

- Release BAPI Function Module.

- Release BAPI object.

Step1. Creating BAPI Structure:

- Go to <SE11>.

- Select Data Type & Enter a name.

- Click on Create.

- Select Structure & hit ENTER.

- Enter the fields from your database. Make sure that the first field is the Primary Key Field.

- Then SAVE & ACTIVATE.

Step 2. Creating BAPI module:

- Enter Transaction code <SE37>.

- Before entering any thing, from the present screen that you are in, select the menu

Goto -> Function Groups -> Create Group.

Enter a name (Note: This name Must start with ZBAPI)

Let this screen be as it is and open another window and there, enter transaction code <SE80>.

Click on Inactive Objects.

Select the group that you just created and click on Activate.

- Go back to <SE37> screen and enter a name and hit <ENTER>. Then enter the group name that you just created and activated.

Now click on the first Tab that says [ATTRIBUTES] and select the radio button that says remote-enabled module since we will be accessing this from any external system.

Then click on the second tab that says [IMPORT].

Enter a PARAMETER NAME, TYPE and the structure you created in the first step. Also select the check box ‘Pa’. All remotely enabled functional modules MUST be Pa enabled, where Pa means ‘Passed by Value’ and if you don’t select ‘Pa’, then that means it will be passed by reference..

Then click on tab that says [EXPORT].

Enter the following as is in the first three fields

RETURN TYPE BAPIRETURN (These 3 field values are always same)

Here also select ‘Pa’ meaning Pass by value.

Note: BAPIRETURN contains structure with message fields.

Then SAVE and ACTIVATE.

Step 3. Creating BAPI object:

- Enter Tr.Code <SWO1> (Note. It is letter ‘O’ and not Zero).

- Enter a name and then click on create. Enter details.

- Enter Application ‘M’, if you are using standard table Mara. If you are using your own database then select ‘Z’ at the bottom.

- Then hit <ENTER>.

- Now we have to add ‘Methods’. High light METHODS and then select the following from the menu: Goto Utilities -> API Methods -> Add Methods.

- Enter function Module name and hit <ENTER>.

- Select the second FORWARD ARROW button (>)to go to next step.

- Check if every thing looks ok and again click on FORWARD ARROW button (>).

- Then select ‘YES’ and click on <SAVE>.

- Now on a different screen goto TR.CODE <SE37>. Enter Function Module name and select from the top menu Function Module -> Release -> Release.

- Goback to TR.CODE <SWO1>.

Here select the menu combination shown below in the same order.

- Edit -> Change Release Status -> Object Type Component -> To Implemented.

- Edit -> Change Release Status -> Object Type Component -> To Released.

- Edit -> Change Release Status -> Object Type -> To Implemented.

- Edit -> Change Release Status -> Object Type -> To Released.

- Then click on <SAVE>.

- Then click on Generate Button (4th button from left hand side looks like spinning wheel).

- Then Click on the button that says ‘PROGRAM’ to see the source code.

To check if this is present in work flow goto transaction code <BAPI>.

Here it shows business object repository.

- First click on the middle button and then select “ALL” and hit ENTER.

- Goto tab [ALPHABETICAL] and look for the object that you created. This shows that the BAPI object has been created successfully.

IDocs

IDocs are text encoded documents with a rigid structure that are used to

exchange data between R/3 and a foreign system. Instead of calling a

program in the destination system directly, the data is first packed into

an IDoc and then sent to the receiving system, where it is analyzed and

properly processed. Therefore an IDoc data exchange is always an

asynchronous process. The significant difference between simple RFC-calls

and IDoc data exchange is the fact, that every action performed on IDocs

are protocolled by R/3 and IDocs can be reprocessed if an error occurred

in one of the message steps.

While IDocs have to be understood as a data exchange protocol, EDI and ALE

are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to

deliver data to the receiving system. ALE is basically the scheduling

mechanism that defines when and between which partners and what kind of

data will be exchanged on a regular or event triggered basis. Such a

set-up is called an ALE-scenario.

HI,

BAPI (Business Application Programming Interface) is an API method of a business object which intern is a RFC enabled Function Module.

Business Objects are the Objects which has business sence associated to it. Ex. Sales Orders, Purchase Orders etc.

The Properties of BAPI are:

Every BAPI name should start with letters 'BAPI'.

It is an API method of a Business Object.

it does not contain a internal COMMIT statement in the Function Module.

It does not contain "CALL TRANSACTION" statements.

BAPI do not raise 'EXCEPTIONS'.

a RETURN structure is defined as an interface parameter of a BAPI which is used to log all the errors, warnings and the successful processes tha are triggered in the course of execution of a BAPI.

A successful execution of a BAPI requires the data to be commited and this process of performing a COMMIT is achieved by calling the BAPI_TRANSACTION_COMMIT' explicitly if there are no errors logged in the RETURN structure.

There are two types of BAPI's: Instance Dependent & Instance Independent.

BAPI provides an access to the SAP system for external applications to have the business data processed in the form of web services. When BAPI's are used to post the data in SAP system these are used as Function Modules.
