Enhancement Frame Work:- Adding custom development to the standard functionality without disturbing the original one is called as an Enhancement. In some cases standard functionalities may not meet our/user requirement. For this SAP has provided hooks to add user functionality to the standard business Scenario.
Initially User-exit were used as mode of enhancement. The user can add his code in custom include program and activate it. The main problem with user exits was that only a single implementation was possible. That means if an enhancement is included in project that cannot be reused as long as the project is active.
To over come this issue SAP has come up with BADI concept which supports multiple implementation.These enhancements were good with transactions some times an enhancement was required on a standard report for this SAP has provided an Enhancement Spots. These Spots can be implicit or Explicit.
