3. Select the Enh. Spot Element Definitions tab page.
4. Choose Create BAdI.
A dialog box appears.
5. Enter a name and a short text for the BAdI.
BAdIs are in the same namespace as global data types from the ABAP Dictionary, global classes, or interfaces. For BAdIs, we recommend using the prefix “BADI_” (or “ZBADI_”, and so on, in the customer namespace).
The new BAdI appears as a node in the tree display of the tab page.
6. On the right-hand side of the page, do the following:
a. Enter the attribute for multiple use.

Here you can:
a. Enter the filter name, filter type, and description.
b. Optional: If you choose Constant Filter Value During Call, you may only specify a constant value at the respective filter when using GET BADI. This is provided for future performance improvements of the statement.
c. Optional: Enter either a data element or a domain with fixed values, or a search help. Alternatively, enter a check or input help class, and a length (together with decimal places). In this way, the filter values specified at GET BADIcan be checked during the BAdI implementation.
