SUM

Description

SUM adds all the values you provide in between a set of brackets, each separated by a comma, and returns the result.

SUM can also return the added total of values in a single list that is produced by another function.

Example: Multiple values

p is Person
SUM(p.base_fee, p.transaction_fee, p.report_fee)

This expression calculates the total of the base fee, the transaction fee, and the report fee regarding a person in a case.

Example: From single list of properties

SUM can also return the added total of values in a single list that is produced by another function.

SUM(get_properties_from_instances(instances(AccountHolder), personal_income))

This expression works in a couple of steps to bring you the result:

• SUM( .... ) is the overarching function, of which you want the result. In between its brackets sits another function.

• get_properties_from_instances(.......) is the function inside the SUM brackets, which goes and fetches the property of the instances you specify. For more information see also get_properties.

• instances(AccountHolder, personal_income) returns the personal income of all the accountholders.

• These three combined, give you the sum total of the personal incomes for all the accountholders in the case.
