BAdI (rather like saying what specific restaurant you want to go to).
6.4 Implementing BAdIs
After you have completed the steps in the previous section, the BAdI definition is
complete. You should still be on the BAdI Definition screen shown in Figure
6.14. Now, the time has come to fill in the Fallback Class section at the bottom
of the screen.
What you are about to create is a defaul t implementation (the so-called fallbackclass).In
Figure 6.21, you ca n see a ticked checkbox in dicating that you want a
fallback class, and that class is given a name. (You really only need a fallback class
for a single-use BAdI, because in that case at least one implementation is mandatory.
With a multiple-use BAdI, it’s fine if no implementations at all are called.)
Figure 6.21 Creating a Fallback Class
This takes you into SE24 again, so nothing to see here; you create the class in the
normal way. The system does ask you if you want the fallback class to show up on
the BAdI definition table as an exampl e implementation, so you could have an
