if u specify destination in bapis dey become remote capable..

(BAPI) Predefined interface to data and processes in an SAP application, which is stored in the Business Object Repository and can be called remotely...i.e. from other systems..

u can read data from other systems and create data in ur system with same details as from other system..

for dis dere must be a valid link b/w 2 systems and also u've to specify destination in bapi call.

plz reward points if dis helps

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

•Documentation of the BAPI

•Generate ALE interface for asynchronous BAPIs

•Generate and release

NOTE:

Here we will not be covering the two points – Documentation of BAPI and Generating ALE Interface for asynchronous BAPIs.

NOTE: You can use the BAPI explorer (T-code BAPI) to get a step-by-step instruction / checklist in how to create a BAPI. In the BAPI explorer select the Project tab.

EXAMPLE – HOW TO CREATE A BAPI

In the example we will create a BAPI that reads some information about the line items for a Sales Invoice from table VBRP based on the Invoice No. that is supplied to the import parameter of the BAPI Function Module.

BAPI Name ZGetInvoiceItems

Function group ZBAPIVIN

Function module: ZBAPI_GET_BILL_ITEMS

FM Import parameters : IV_BILLNO TYPE ZBAPI_BILL_ITEMS-VBELN

FM Tables :IT_VBRP LIKE ZBAPI_BILL_ITEMS

FM Export parameters : RETURN LIKE BAPIRETURN

Defining BAPI 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. Use Data type -> Structure

In our case we do not have multiple inputs but just one input i.e. Sales Invoice No. and so we have not made use of any structure for the purpose. But if required, structure can be used for import parameter also.

The following are the components of structure ZBAPI_BILL_ITEMS:

Field Name Description

VBELN Invoice Number

POSNR Invoice Item Number

MATNR Material Number

FKIMG Quantity

VRKME Sales Units (Quantity)

NETWR Amount

Point of Caution

It is required to define a structure for every parameter in the BAPI and use of same structures which are used in existing applications cannot be done because BAPI structures are frozen when BAPIs are released and then there are restrictions on changing them.

Screenshot of Structure – ZBAPI_BILL_ITEMS

Creating BAPI Function Modules (For each method)

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

Screenshot of Attributes Tab in the FM ZBAPI_BILL_ITEMS

Screenshot of Import Parameters Tab in the FM ZBAPI_BILL_ITEMS

Screenshot of Export Parameters Tab in the FM ZBAPI_BILL_ITEMS

NOTE:

Since Remote Enabled module processing type is selected and the Import/Export parameters can only be BY VALUE for an RFC enabled function module, select the checkbox for Pass Value for each IMPORT/EXPORT parameter.
