Figure 6.13 Creating a BAdI Definition: Part 1
Figure 6.14 Creating a BAdI Definition: Part 2
On the screen in Figure 6.14, there are a lot of nice buttons to press and boxes to
check. The first screen area is called Usability. You will see that by default Multiple
Use is on. A single-use BAdI is one in which only one implementation of the
BAdI is ever going to be called at an y one time. A multiple-use BAdI is one in
which between one and one trillion bill ion million (approximately) BAdIs are
called in a random order, depending on how many implementations have been
created. In OO terms, this is like raising an event, often called the publish–subscribe
pattern.
