Query On BADI

[former_member200116]

Hi helpers,

I am beginner in this area and have few queries which are not cleared after searching the existing posts.

• This is with reference to Available SAP BADI.

1. What is the exact use of the Adapter Class in BADI ?

2. All the implementation for the BADI's are called by the program. Then how can I call the specific implementations for the same BADI as I do not want to call all the implementations . Is FILTER technique relevant here ?

Thanks in Advance

Regards

Adapter class :When we creates an interface for this Add-in enhancement management generates an adapter class for implementing the interface

When you implement An interface with 'IF_EX_' inserted between the first and second characters of the BAdI name and

An adapter class with 'CL_EX_' inserted between the first and second characters of the BAdI name.

Filter : Yes filter is used at this scenario The advantage of filter is Business Add-ins may be implemented depending on a specific filter value (example, country-specific versions: Distinct implementations of the BADI can be created for each country). A filter type must be entered when defining your enhancement (a country or industry sector, for example). All methods created in the enhancement's interface have filter value ' FLT_VAL' as their import parameter. The method then selects the active implementation based on the data provided in the filter value.
