In Blue Prism, what is a stage Expression?

In Blue Prism, an expression is a statement that is evaluated at runtime to produce a value. It is essentially a formula constructed from data items, literals, operators, and built-in functions. Expressions are fundamental components used within various stages, most notably the Calculation stage to compute a result and the Decision stage to evaluate a condition to either True or False, thereby directing the process flow. The expression itself is the logic or formula, not the resulting output or descriptive text.

B. An output from a Decision stage is a control flow path (e.g., 'True' or 'False'), which is determined by the evaluation of an expression, but it is not the expression itself.

C. The description of a Blue Prism stage is a text field used for documentation and annotation; it is not a formula and is not executed by the process.

D. The output from a Calculation stage is the value produced by the expression, which is then stored in a data item. The expression is the formula used to generate that output.

1. Blue Prism Official Documentation Portal: Data Types and Expressions Guide. In the "Expressions" section

it is stated: "An expression is a statement that can be evaluated to produce a value. Expressions are made up of data

contained in data items

and literals

which are manipulated by operators and functions." This directly supports that an expression is a formula used to produce a value.

2. Blue Prism Official Documentation Portal: v7 User Guide - Process Studio. In the section "Calculation Stage

" the guide describes the 'Expression' field as the area where the user enters "the expression to be evaluated." The 'Store Result In' field is separately defined for the output value

distinguishing the expression from its result.

3. Blue Prism Official Documentation Portal: v7 User Guide - Process Studio. The "Decision Stage" section explains that the stage "evaluates an expression" to determine which of two paths to follow. This reinforces that the expression is the evaluative logic

not the resulting path.
