Functions and characteristics without failures
Explanation:
A search for functions and characteristics that have no failures will be performed
Example:

- This structure consists of three structure elements, each of which have two functions (
),  one product characteristic (
) and one process characteristic (
) assigned. - It is possible to see from the structure list which functions and characteristics do not have failures.
 
Search result: ![]()
The following are hits in this Quality Rule: function Fn2 and the three process characteristics PrcC1, PrcC2, PrcC3. For this rule, it is not important whether the functions, characteristics or failures are linked in nets.
