:=

Description

:= always has an information field on its left (domicile, risk_level, etc.), and any kind of expression on its right side.

Attaching a condition with := to a field, means the field will only be assigned a value based on this condition if it doesn't already have a value. If a user has already provided a value for the field, the system will not override that value.

This operator can only be used when writing the assignment part of a process rule.

Examples

p is Person
---
p.tax_country := p.domicile

The field tax_countrywill be assigned the same value as the field domicile, unless another value for tax_countryhas already been provided.

c is Contract
---
c.service := asset_management

The service attached to this contract will be 'Asset Management', unless another service has already been entered in the field service.

p is Person
---
p.full_name := CONCAT(p.first_name, ' ', p.last_name)

The field full_name will receive a value that is the combination of the values in the fields first_name and last_name, separated by a space. Again: only if the field full_name hasn't already been assigned a value.
