Issue citing
Issue citing is another way of filtering your detected issues. For example, changing an issue's status to Ignore indicates that this issue was found in code that you don't care about.
The default status filtering shows only issues in Analyze and Fix status. Use "Not a Problem" status to handle isolated false positives for a particular issue type (for example, CL.FFM.ASSIGN).
On the other hand, if there's an issue type that you really don't care about, you can disable it using the Configuration Editor, which is an entirely different activity from filtering. Enabling and disabling issues is one way of customizing your analysis.
