They are two different methods to do the same thing: to check and update the data into std trx.
The user-exit is the old concept based on function module
The BADI is the new concept based on OO ABAP.
So you can often to find a BADI and an USER-EXIT to do the same thing and you have to decide what you prefer to use.
Anyway the new trx and the enjoy trx use BADIs as exit

Hi,
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.
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.

What is difference between badi and user-exists?
What is difference between enhancements and user-exists? and what is the full form of BADI?
I have another doubt in BDC IN BDC WE HAVE MSEGCALL (i did not remember the > correct name) where the error logs are stored, MSEGCALL is a table or structure.
What is the system landscape?
1) Difference between BADI and USER-EXIT.
i) BADI's can be used any number of times, where as USER-EXITS can be used only one time.
Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.
ii) BADI's are oops based.
2) About 'BDCMSGCOLL' it is a structure. Used for finding error records.
3) Full form of BADI 'Business addins'.
3) System land scape will be depends on your project
Ex:- 'Development server'>'Quality server'-> 'Production server'......

Hi Spart,
<b>BADI</b>
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects.
Badis allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like).
Business Add-Ins can be created at each level within such a system infrastructure
Some BADI can have multiple independent implementations which is much better for software deployment as several developers can implement the same BADI independently.
<b> User-exits(modifications)</b>
USER EXITS are FORMS and are called by SAP standard programs using PERFORM.
Inside the form (user exit) you can read and change almost any global data from host program.
User exits are more flexible because you have more information to use in your code but on the other hand , it is very easy to manipulate erroneously global data and lead the standard program to a dump or even to make database inconsistent.
User-exit doesnt have any classification.
Basically designed For SD module
User-exits can be written only using access-key
With user-exits the code , the developer has written will not be there for next version unless modification assistance tool is used
<b>Customer-exit</b>
CUSTOMER EXITS(enhancements) are FUNCTIONS so they are called using CALL FUNCTION (or more exactly CALL CUSTOMER FUNCTION
customer exits assumes a two-level infrastructure (SAP and customer solutions)
Customer-exit implemented in one project cannot be implemented in other.

Hi,
BADI is just an object-oriented version of user-exit. Instead of entering program code into some function module (as in customer-exit), you define some class which has to implement predefined methods and those methods are fired at predefined points just like an old user-exit. Some BADI can have multiple independent implementations which is much better for software deployment as several developers can implement the same BADI independently.
