    Key Features

    • Condition Builder: Create complex condition sets using logical operators (AND/OR) and manage conditions with easy-to-use buttons.
    • Field Descriptions: Each condition includes fields like Condition description, Source, Operator, and Value, which guide users in defining conditions clearly.
    • Else If and Else Statements: Specify alternative conditions if initial conditions are not met, enhancing decision-making flexibility.
    • Log Management: Define log levels and messages, and manage output types to capture relevant information during policy evaluations.
    • Calculated Fields: Use numeric operators to perform calculations within policies, supporting complex evaluations.

    Key Outcomes

    By utilizing policy logic condition fields, ServiceNow customers can create robust policy evaluations that enhance compliance management. This functionality allows for precise condition definitions, the ability to log decisions effectively, and the performance of calculations to drive accurate policy outcomes. Ultimately, this leads to improved governance and operational efficiency.

    Policy logic is a set of conditions that is used for determining whether a policy is compliant or non-compliant. You can use the condition builder to specify conditions for the policy.

    Select the or and and button to add multiple rules in the condition set. Select the minus icon Minus icon. to delete a condition.

    You can add a condition set by selecting the New condition set button.

    Table 1. If and else if statement fields
    Field Description
    Condition description Description of the field.
    Source Variable of the source for the condition.
    Operator List of operators to filter the source for the condition. The list changes depending on the source selected.
    Value Value to enter text. Select the Data picker icon Data pill picker icon. to concatenate multiple text strings with multiple data pills to select a variable for the log.
    Note:
    If your Source is choice, the Data pill picker icon is inactive.

    The else if statement enables you to specify a new condition if the first condition is false. The else statement enables you to specify a new condition if it does not apply to the if statement.

    You can add a dependent condition by selecting or or and next to the condition.

    Table 2. Then and else statement fields
    Field Description
    Logic type Select the logic type of the policy:
    • Decision: Determines if the policy is Compliant or Non-compliant.
    • Run policy: For nested policies, the parent policy will return the decision of the child policy that has been selected in the builder.
      Note:
      PaCE supports nesting policies for decision-making and up to two levels are supported, a child and a grandchild.
    Log level Level of the log.
    Log message Log message field to enter text or select the Data picker icon Data pill picker icon. to concatenate multiple text strings with multiple data pills to select a variable for the log.
    Output type Output type of the log. You can select the plus icon Add icon. to add multiple output types or the minus icon Minus icon. to delete the output type.
    Data Data field to enter text. Select the Data picker icon Data pill picker icon. to concatenate multiple text strings with multiple data pills to select a variable for the log.

    The following images show you are able to use the data pill picker to concatenate data in the fields:

    You can see a list of the data sources under the Data source tab.Data source tab.

    You can calculate fields using numeric operators and use these variables to calculate the desired value in a policy logic.
    Note:
    This only supports numeric fields.
    Table 3. Calculated fields
    Operator Description
    Plus (+) Add variables and constants. For example, "Var1 + Var2..."
    Minus (-) Subtract variables and constants. For example, "Var1 - Var2..."
    Multiplication (*) Multiple variables and constants. For example, "Var1 * Var2..."
    Division (/) Divide variables and constants. For example, "Var1 / Var2..."
    Parentheses () Use parentheses to support the order of operators.
    calc[] Use the brackets to evaluate an expression.

    You can mix and match between the operators. For example, "Var1 +Var2*Var3 / Var4".
