option shown at the bottom left of Figure4.11. However, as opposed to the Code
Inspector equivalent in the ATC screen, there are two documentation lines:
왘 Check Title
Gives a description of the general group of errors you’re looking at with a list
of the individual checks.
왘 Check Message
Gives a description of the specific chec k that failed. In lower releases, this
seems not to work all the time; you sometimes only get the description of the
group of checks.
4.2.4 Dismissing False Errors
If you look back briefly at Figure 4.10, you will notice that it shows over 15,000
priority one errors just from one develo per. Unfortunately, when you first run
this for yourself you are likely to get such a result, and some of the check messages
say dire things, like Very Serious Error. When you first see this, you may
be horrified and want to jump off a bridge before anyone else discovers the woeful
state of your code.
In fact, things are in no way as bad as they may appear at first. Obviously, every
error message needs to be looked at, but such messages appear in groups of similar
errors. Although some problems are crying out to be fixed, some of the
“errors” are not in fact problems at all, but just the check tool being overzealous.
This brings us to the subject of false errors and, more specifically, false positives.
A false positive is an alert that an error has oc curred even though everything is
actually fine. To take an example from the real world, it was a false positive when,
in the former Soviet Union, a pigeon flew into a radar dish and triggered a warning
saying that the United States had just launched a massive nuclear attack. (The
rules, which the communication officer broke, said that he should have informed
his superiors—who would have instructed him to counterattack, thus causing a
nuclear war that would have destroyed the world. So it’s lucky he didn’t trust his
country’s own technology.)
Fortunately, in SAP terms, false positives are not that drastic. A common situation
in which a false positive may occur is when you have a variable that should
sometimes, but not always, be changed based on the value of another variable.
In order to make sure that this variable is changed as required, you could use a
