# Configuring compatibility rules

# Configuring compatibility rules for horizontal relationships {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
As a provider, you can use compatibility rules to establish horizontal relationships between the specifications of multiple products, services, or resources.

You use a compatibility rule to define a source specification and a target specification and to establish a relationship between them.  
The ServiceNow AI Platform provides two types of relationships that you can use to define a compatibility rule:

1. Requires: The source specification requires the defined target specification.
2. Excludes: The source specification excludes the defined target specification.

While you're creating a compatibility rule, you can establish the horizontal relationship either by defining the specifications or by defining the details for the specification characteristics. You can also define the maximum and
minimum quantity of the specifications to support and fulfill your customer orders according to the defined decomposition rules.  
Before you can capture a new customer order that has a horizontal relationship, you must configure the compatibility rules by defining the source and target specifications. To learn more, see:
