13.4.1
If a BLPU is a grandchild (it has a Parent BLPU, and that Parent also has a Parent BLPU), it is important to understand how LPIs are maintained to ensure consistency of data capture.
13.4.2
In this example of an office, the method for recording the grandchild property in LPI Records is shown.
PARENT:
PAO_START_NUMBER
LPI

PAO_TEXT
LPI
“Pineapple House“
STREET_DESCRIPTOR
STREET DESCRIPTOR
“Victoria Lane“
TOWN_NAME
STREET DESCRIPTOR
“Stevenage“
POST_TOWN
LPI
“Stevenage“
POSTCODE
LPI
“SG1 1XA“
CHILD:
SAO_TEXT
LPI
“East Wing“
PAO_START_NUMBER
LPI

PAO_TEXT
LPI
“Pineapple House“
STREET_DESCRIPTOR
STREET DESCRIPTOR
“Victoria Lane“
TOWN_NAME
STREET DESCRIPTOR
“Stevenage“
POST_TOWN
LPI

In this situation, the grandchild created can be processed like other LPIs to produce this address:
Suite 3
East Wing Pineapple House
5 Victoria Lane
Stevenage
SG1 1XA

This method can be further extended to great grandchildren, if necessary.
