Difference between User exits , BAPI and BTE

Hi ,

Can any one tell me the difference between User exits, BAPI and BTE. It would be great if you provide me the example scenario & step by step process for BAPI and BTE.

    User Exits are functions that can be included inside a program, to extend it's funcionality...

    <b>CMOD and SMOD</b>

    BAPIS are Function Modules created to fulfill payment and contabilization tasks....BAPIS never produces short dumps and safer to use than Batch-Inputs...


    BTE are Business Transaction Events, something like User Exits but no longer used....BADI's are their replacement....


    Don't remember about BADI's transactions....They don't exist on 46C....

    <b>Difference Between BADI and User Exits


    Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.

    As with customer exits two different views are available:

    In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.

    <b>Difference between BADI’s and BTE’s</b>

    The concepts behind the Business Add-Ins enhancement technique and Open FI are basically the same. However, the two enhancement techniques do differ from each other in the following points:

    Open FI can only be used to make program enhancements, that is, you can only enhance source code using Open FI. You cannot enhance user interface elements with Open FI like you can with Business Add-Ins.

    Open FI assumes that enhancement will only take place on three levels (SAP - partners - customers), whereas with Business Add-Ins you can create and implement enhancements in as many software layers as you like.

    Open FI uses function modules for program enhancements. With Business Add-Ins, ABAP Objects are used enhance programs.

    In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.

    In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.

    SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.

    The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example).

    All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.

    The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects.
