# Manage Rules

:lock: Product.**Edit**

## Overview

This operation is used to manage the Rules of the Characteristics of the Product.

## Setup

No specific setup is required other than to meet the precondition of the transaction.

## Preconditions

* Product exists in the system and it is Created.

## Sequence of Steps

The Manage Rules wizard can be called from the **Product** page by selecting **Characteristics and Rules** from the section menus on the right, and then selecting the **Rules** tab.

### Step 1: Context

1. Specify as many contexts as you need by using :material-plus:. You can also delete or order information, and use the Search to find a specific **Step**.
2. Specify the Context Details by providing the following for each:
      * Step
      * Logical Flow Path (optional)
      * Context (BOM, Checklist, Data Collection, Document, Durables, Recipe, Recipe Parameter, Service, and Inspection Plan)

    !!! info
        For the same Step, there cannot be two Rules where one Rule defines a Logical Flow Path and another does not. Hence, for the same Step, either all Rules define a Logical Flow Path or all Rules do not define one.

    !!! info
        The Step and Logical Flow Path Order is defined by you and you can choose to change the Step Order, which will affect all Rules of that Step and Logical Flow Path combination.

3. Select **Next** to continue.

### Step 2: Rules

1. Specify as many **Rules** as you need by using :material-plus:. You can also delete or order information, and use the Search to find a specific **Step** or **Context**.
2. Specify the Rules Details by providing the Condition:
      * If needed use the Help Condition
  
        ![Screenshot showing a help condition for managing rules.](images/manage_rules_help_condition.png)
  
      * The Product Characteristic Rule Condition supports a subset of the JSONata query syntax. If needed use the :octicons-info-16: icon to view supported expression format as follows:
        * Equal to/Not equal to comparison operators ('='/'!=').
        * Less than/Less than or equal to comparison operators ('<'/'<=').
        * Greater than/Greater than or equal to comparison operators ('>'/'>=').

            !!! info
                These operators work with strings and numbers, so on writing the conditions, you must ensure you understand when you want to compare strings and when you want to compare numbers (do not use inverted commas).<br>Additionally, if you intend to compare numbers, guarantee that the source Lookup Table only has numeric values.

        * And/Or boolean operators ('and'/'or').
        * Boolean values for ensuring a expression are always true or false ('true'/'false').
        * Quotation marks to define Product Characteristic values (for example, "Dark Blue" or 'Soft Blue').
        * Reference to Product Characteristic without whitespaces (for example, Color = 'Blue').
        * Reference to Product Characteristic with whitespaces or special characters (for example, \`Wheel color\` = 'Blue')
        * Parentheses for precedence in compound expressions (for example, Color = "Blue" and (Size = "Small" or Size = "Medium") ).

    !!! note
        The system validates only characteristic values defined in Lookup Tables, and autocomplete suggestions during condition editing are available only for characteristics linked to those Lookup Tables.

3. Specify other mandatory information depending on the selected contexts.
