Which of the following is not a valid return type of a custom formula?

1. Date

2. Decimal

3. Text

4. Array

The correct answer is: Array

In Salesforce, when creating custom formulas, the return type defines the kind of value that the formula will produce. The valid return types for custom formulas include Date, Decimal, and Text. A Date return type is used when the formula calculates or returns a date value, making it suitable for situations that involve date-related functions, such as calculating the difference between two dates. A Decimal return type is essential for formulas that involve numerical calculations requiring decimal precision, such as financial figures or other metrics where fractional values are relevant. Text is the return type used when a formula produces a string output. This is beneficial for creating concatenated strings or textual representations of other values. The Array return type is not a valid return type for custom formulas in Salesforce. Formulas are designed to return a single value of a particular data type, and the concept of arrays does not fit into the single-value return format that formulas enforce. Therefore, this option is correctly identified as not being a valid return type for custom formulas.
