Filter Editor

The filter editor lets you create filters for selected items. In a table style for example, we can filter the devices Existing, that do not have an associated Section.

In the image we see the buttons:

• Add Lines - to add rows to the table
• Remove Lines - to remove selected lines

In the table, we have the following columns:

• Concatenator - concatenates a sub-expression with another, creating the logic of the expression
• ( - to add parentheses, which can change the execution order of sub-expressions
• Property - choose a property that can be evaluated
• Operator - it is the operator doing the check. It compares the property value with a predefined value, or another property from a row below or above, depending on how it is configured
• Use Value - check to use an absolute value (number, text, etc) or uncheck if to use a value of another property
• Value - if the box above is checked, enter a value. Note that it assumes the unit of measure of the selected property.
• ) - to close the open parentheses. Note: you can change the execution order of sub-expressions

Add as many lines as necessary and fill in the necessary data to form a mathematical expression that can be evaluated, as in the example:

Watch the bottom of the screen, it will show information regarding the expression:

• Critical - the expression cannot be evaluated as it contains syntax errors
• Warning - there is no expression that can be evaluated
• Neutral - the resulting expression is well written and can be evaluated
