Coding Action Validations
The generated class for each action vali dation implements the same interface as
the generated class for consistency validations—namely, /BOBF/IF_FRW_VALIDA-
TION. Therefore, the CHECK_DELTA and CHECK methods have the same meaning,
and there is no need to restate that information here. However, it’s worth taking
a look at the coding for the action validation for the sake of completeness.
First off, create a new message, which wi ll be shown to the users if they try to
execute the action and the data is incorrect (Figure 8.26).
Figure 8.26 Action Validation Error Message
Then, add that message to your monster exception class (Figure 8.27).
