BAPI uploading data

[Former Member]

Hi Experts,

I want to how exactly BAPI's are used as interfaces and for data transfering . Please provide me example codes for uploadinfg data into r/3 using BAPI's.

Thanks in advance.

Points will be awrded surely.

You need a FM or BAPI in R/3 which modify the table. This FM should be cal by a buttom in your VC...you can have a look to this document

Hi,

Umakanth.

Business Application Programming Interfaces enables the user to access the business objects from one R/3 system to another.

And at the same time the BAPIs in the Business Object Repository have the openness to be accessable from other software applications like Java, visual basic, etc.,

For its creation u follow the steps:

1. Create the structures like zkna1 and zvbak.

2. write a function module to obtain the sales details by giving the importing parameter as kunnr.

The function module must be remote enabled and the parameters must be only pass by value type.

3. Release the function module.

4. Go to SWo1 and give the function module that u have created as a method and implement it then release it.

5. Now implement ur bapi that was created in SWO1 in ur calling program and pass the appropriate parameters according to ur requirement.

Reward if Helpful.

Hi umakanth ,

A BAPI is defined as a method of an SAP Business Object.

To use a BAPI method, an application program only needs to know how to call the method; that is, it needs to know the method's interface definition. A BAPI interface is defined by:

Import parameters

Export parameters

Import/export (table) parameters

The BAPIs in the R/3 System are currently implemented as function modules, all of which are held in the Function Builder. Each function module underlying a BAPI:

· Supports the Remote Function Call (RFC) protocol

· Has been assigned as a method to an SAP Business Object in the BOR

· Is processed without returning any screen dialogs to the calling application

steps involved in BAPI

In the application hierarchy of the BAPI Browser you can display all the SAP business object types for which BAPIs have been implemented:

Tools ->Business Framework -> BAPI Browser : BAPI45.

Expand the nodes and the subordinate nodes of one of the application components

To open an object type, double-click on it.

To display a list of the key fields of the object, expand the node Key fields

To display a list of the BAPIs available for this SAP business object type, expand the node Methods

To display the parameters of a BAPI, expand the node for the BAPI and then the Parameters node

Eg Program:

BAPI_GOODSMVT_CREATE to post Goods Movement 

The following is an abap program making used of the BAPI function BAPI_GOODSMVT_CREATE to do Goods Receipts for Purchase Order after importing the data from an external system.

* GMCODE Table T158G - 01 - MB01 - Goods Receipts for Purchase Order

*                      06 - MB11
*
* Domain: KZBEW - Movement Indicator
*      Goods movement w/o reference
*  B - Goods movement for purchase order
*  F - Goods movement for production order
*  L - Goods movement for delivery note
*  K - Goods movement for kanban requirement (WM - internal only)
*  O - Subsequent adjustment of "material-provided" consumption
*  W - Subsequent adjustment of proportion/product unit material
