a!customFieldSum( value )
Used to create a custom record field, this function returns a sum of values. You can calculate the sum of record fields, related record fields, or literal values of type Number (Integer) or Number (Decimal).
Keyword  Type  Description 


Any Type 
An array containing any combination of record fields, related record fields, or literal values to be summed. You must have at least two values in the array. 
The a!customFieldSum()
function can only be used to create a custom record field that evaluates in real time. This means you can reference related record fields, constants, and other supported functions in your calculations.
To create a custom record field that evaluates in realtime:
Enter an expression using any Custom Field function.
Note: Custom record fields that evaluate in realtime must use at least one Custom Field function.
You can use the a!customFieldSum()
function in conjunction with other Custom Field functions, like a!customFieldSubtract(), a!customFieldDivide(), or a!customFieldMultiply() to create the calculations you need.
See the Realtime evaluation recipes for an example.
Let's say you want calculate each employee's total salary, which includes their base salary, restricted stock units (RSU), and an annual bonus that is only applied if they qualify.
On the Employee record type, you could create a custom record field that evaluates in realtime so you can add the baseSalary
field, the related record field rsuDollarAmount
, and the related record field annualBonus
. However, the annualBonus
field will only be included in the calculation when the constant cons!DISCRETIONARY_BONUS
is true.

}
)
In addition to record fields, related record fields, and other custom record fields, you can reference any of the following supported functions in the value parameter of a!customFieldSum()
:
Note: You must reference at least one record field, related record field, or another Custom Field function in the value parameter.
