    Key Features

    • Condition Builder: Users can add conditions using and / or buttons, delete conditions with the minus icon, and create new condition sets.
    • If and Else If Statements: Define primary and alternative conditions, with options to specify dependent conditions.
    • Logic Type: Select between Decision (for compliance status) or Run policy (to evaluate nested policies).
    • Log Configuration: Customize log levels, messages, and output types, utilizing a data picker for concatenating multiple strings.
    • Calculated Fields: Perform mathematical operations using a variety of numeric operators to compute values in policy logic.

    Key Outcomes

    By effectively utilizing policy logic condition fields, ServiceNow customers can streamline their compliance checks, enhance decision-making processes through nested policies, and customize logging for better tracking and reporting. This ultimately aids organizations in maintaining regulatory compliance 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:

    Data concatenated.

    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".
