--- Difference between BADI and Customer Exit

BADI	Customer-exit
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects.	CUSTOMER EXITS (enhancements) are FUNCTIONS so they are called using CALL FUNCTION (or more exactly CALL CUSTOMER FUNCTION
Badi’s 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	Customer exits assumes a two-level infrastructure (SAP and customer solutions)
Some BADI can have multiple independent implementations, which is much better for software deployment as several developers can implement the same BADI independently.	Customer-exit implemented in one project cannot be implemented in other.
