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. 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:
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.
Logical Operator
Uses the And/Or expressions enabling more than one filter to be used to a rule.
