You use the Filter tab to create filters for use in your rules. Note that not all rules require a filter
Operand 1 — Enables you to select a rule component specified in the Rule Components tab.
Property — Allows you to select from a list of appropriate properties for the rule component that you select from the Operand 1 list.
Function — Enables you to select, if required, a function that will be applied to the selected property;
-
Length - Number of characters in string
-
Lower - String is lowercase
-
Substring – Part of the property string
-
Trim – Removes empty spaces before and after the property string
-
Upper – String is uppercase
Start — A numeric value only used with a Function substring to set the start point for the substring.
Length — A numeric value only used with a Function substring to set the length of the substring.
Operator — Enables you to select an operator for the logical relation. For more details, see Operator Descriptions.
Operand 2 — Enables you to select a rule component specified in the Rule Components tab, or select the Value operand of a property selected in the Property column. If you select a rule component, you create a relationship between properties of rule components. If you select the Value operand, you create a relationship between a rule component property and the property value.
Property/Value — Enables you to choose from a pick list where applicable. This applies to support table properties, plant group properties, or properties that are Boolean. If in the Operand 2 column you selected a rule component, you can select a property of a specific item type. If in the Operand 2 column you selected the Value operand, you can type a value for the property defined in the Property column. Depending on the operator, a value can be free text or a number of units of measure separated by commas or semi colons.
When you type a unit of measure, the software converts the value automatically to
the default units of measure defined in Smart Instrumentation.
Function — Enables you to select, if required, a function that will be applied to the selected property;

Start — A numeric value only used with a Function substring to set the start point for the substring.
Length — A numeric value only used with a Function substring to set the length of the substring.
Logical Operator — Uses the And/Or expressions enabling more than one filter to be used to a rule.
