BADI

Business Add-in Definition

Name of the definition of a business add-in (BADI). Business add-ins are SAP’s new enhancement concept. There are two different views:

• In the definition, you create an enhancement that is called from the application code

• In the implementation,  you save the code for the functions for the enhancement

You create business add-in definitions using transaction SE18. They contain the business add-in interface. In the application code the instance variable is typed according to this interface. You can create several implementations for each add-in definition.
There are two main types of BADI definitions:

• Multiple use – that is, there can be several active implementations
• Filter-dependent  – that is, you apply a filter value to each method called (for example, a country). A  different (active) implementation is then called for each value. Possible filter values are characterized by the filter type.
