SAP provides the developers with the freedom to add enhancements to the standard function modules. There can be requirements when standard functionalities may not offer some of the functionalities that system demands. Such demands can be accomplished by adding some functionality to SAP standard function modules.
Initially User-exit was 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.
