Parent rules allow you to create logical sets between several shipping cost rules.
They are used to establish hierarchical or conditional relationships between different rules, thus offering a more precise and flexible management of your delivery calculations.
Thanks to this feature, you can:
Combine several rules to create complex scenarios
Define application conditions between rules: a rule applies only if another is validated
Optimize performance and readability by grouping similar rules under a main rule
Imagine you want to implement a differentiated delivery policy for your professional clients in France (Shipping costs from 100€, surcharge of 20€ for deliveries to Corsica).
You could create a parent rule entitled: Professional Clients Delivery France
This parent rule would serve as a logical container for specific sub-rules.
