Empty IF-Branch Check

What is the intent of the check?

This check searches for empty branches of IF statements.

How to solve the issue?

Fill the empty IF structure with code or remove it by refactoring the condition.

What to do in case of exception?

In exceptional cases, you can suppress this finding by using the pseudo comment "#EC EMPTY_IF_BRANCH which should be placed after the opening statement of the empty IF branch; or, in case of nested IFstatements, in the deepest structure within the branch.

Note that this check is the same as a check in the Extended Program Check (SLIN) delivered by SAP. That check accepts a pragma for suppressing its findings that Code Pal cannot evaluate (pragmas are inaccessible to ordinary Code Inspector checks). We recommend that you either use this Code Pal check or the corresponding SLIN check, but not both, since if you use both you get two findings for the exact same issue.
