User Exits are the Procedural Approach Of Enhancements.
Business Add-Ins are the Object Oriented Approach of
Enhancements.

User Exits can be used in Only one project. That means we
can give only one implementation for User Exits.
Where as for BADIs we can give multiple implementations.

With BADIs No need to register in SSCR.( SAP Software Change
Request ) .

Answer / dushyanta kumar

User Exit is normal abap enhancing in Standard SAP .
BAdI is enhancing the object oriented approach.

Answer / rams

user exit can be called only once, Badi can be called N
number of times

user exit is not object oriented , BDAI is object oriented

user exit t-codes are CMOD SMOD , BADI t-codes are SE18 and
se19

in User exits we will code in standard sap program so if
there an upgrade then we may loss the code. that will not
happen in case of BADI's

when we use bdc and lsmw and bapis and ale idocs
