Adding & Editing Properties - Parent/Child Relationships

ℹ️ Overview

Properties can be related in a hierarchical structure, defining their relationship across one or more levels.

• Parent BLPU → Represented by an LPI with an entry in the PAO but no entry in the SAO.

• Child BLPU → Represented by an LPI with an entry in both SAO and PAO.

👉 In most cases, the Child inherits the PAO from its Parent, but this is not mandatory for every level in the hierarchy.

🔗 Parent UPRN in DTF 7.3

From DTF 7.3, a Parent UPRN field is included to record the Parent UPRN on Child BLPU records.

• When a Parent/Child relationship is created or updated, this field is populated automatically.

• The field can also be edited manually if required.

• On a Child record, the main LPI determines the BLPU Parent UPRN field.

🏗️ Creating a Parent Property

1. Create a property as normal, following the usual process for adding a symbol.

2. The property will automatically qualify as a Parent Property.

3. It will then be added to the Parent Property List, making it available for linking potential Child properties.

👶 Creating a Child Property

➡️ Once a Parent property exists, you can then link new or existing BLPU records as Child Properties.
