Creating Rules in BRFplus: Basic Example 9.2
How dare BRFplus come along and tell us it can do this better! Look at how it handles
the same task.
9.2 Creating Rules in BRFplus: Basic Example
This section walks you through the basic steps in creating rules in BRFplus, which
consists of three main steps: creating an application, adding rule logic, and calling
the BRFplus function in ABAP.
9.2.1 Creating a BRFplus Application
To start creating a BRFplus application, call Transaction BRFplus or BRF+ (either
will do; both transactions call the exact same program). Depending on your system
settings, you may be asked for your user name and password again. The first
time you run the transaction you may see a whirling circle for a few minutes;
afterwards, the BRFplus screen appears.
Note
The screens in BRFplus look very different depending on what version of SAP you are
running. This is one product that still ha s a large number of enhancements coming
through in each support stack.
Like Russian nesting dolls, you have to create many layers when creating an
object in SAP, and the same is true here. The innermost doll is the rule, and the
outermost doll is the application. You start with the outside—the application—so
click the Create Application button. The screen shown in Figure 9.6 appears.
In Figure 9.6, you can see the screen for creating an application, with all the standard
fields: Name, Short Text, and Text. Before version 7.4 you did not have to
start the name of applications with “Z” in this framework; you still don’t have to
in 7.40, but you get a warning if you don’t. When you get deeper inside of BRFplus
it’s best to have some sort of naming convention so that you can tell different
types of objects apart by looking at their technical names.
In the Storage Type field, you have three options: Master Data, which lives in
the current system and does not get transported, Customizing, which is clientdependent,
and System, which is like a workbench object.
