How to work with Formulas and Calculated Fields

The Formulas feature has been designed to enable operations to be performed automatically by PowerClerk by using references to Data Fields and constants. These can be used to create logical conditions such as to selectively run Automation action rules, create Validation rules for Automations, create Conditional Visibility rules, and much more. An intuitive drag-and-drop Formula editor is used to configure Formulas.

Calculated Fields are different than Formulas in that they are discreet Data Fields. This means that unlike Formulas, they house the data result of the Formula as a part of the project record. This allows the calculated results to be displayed real-time on Forms, to be used in Project List Columns, or to run local calculations for the purpose of more detailed Reporting.
 
Formulas can perform numeric operations (E.g. addition, subtraction, multiplication, division, etc.), Boolean operations (greater than, less than, is equal to, is same as, is not same as, etc.) on numeric data fields, and can also perform Boolean operations (is equal to, is not) on Boolean data fields (true/false). PowerClerk can also run calculations that result in a Date data field and run specific operations on Multi-Instance data fields such as tables. A few examples have been provided in Figure 2 and Figure 3 below. The top-right of the formula editor will tell you the data type that the formula result will be in.
 

Once a Formula has been saved, you can create a Calculated Field (Fig. 4) to use on your Forms, as Project List Columns, or in a Report. The definition of a Calculated Field cannot be edited. Additionally, any changes to the original formula after the Calculated Field’s creation will not be reflected in the Calculated Field, and a new one will need to be created. If editing a calculated field is needed, you must select “Copy to New Formula”, edit the newly created formula, and then create a new Calculated Field from the newly edited formula.
 
In the example in Figure 5 below, the Calculated Field created from the Formula comparing Estimated Annual Production to Historical Annual Consumption (kWh) designed in Figure 3 above populates the result automatically in the Form and updates automatically as data field values change.
 

 
Formulas can also be used within Automations to trigger Action Rules as shown in Figure 6 below:

Multi-Instance Formula Operators (valdation of multi-instance fields to ensure all field instances adhere to the desired criteria)
Operator	Description
	Returns Boolean True if all instance values across the entire multi-instance field match, or False if not.
	If all values across the multi-instance field match, returns that exact single value (whether that value is Numeric, Text, Boolean, or Date).
	Returns the summation of all values across a multi-instance field of Numeric data type.
	Provides an integer value (e.g. 1, 2, or 3, etc.) based on the number of Boolean (e.g. Checkbox) “True” values are found across the multi-instance field.
	Provides an integer value (e.g. 1, 2, or 3, etc.) based on the number of matching Text (e.g. Single Line Text) values that are found across the multi-instance field.

Dynamic Formula References

Use Dynamic Formula References to simplify complex Formula expressions by referencing existing Formulas as components (or Formula segments) of the larger Formula. My defining simple formulas first, these can then be “nested” into a larger formula to create more complex definitions.
 
To reference a Formula within another Formula, please use the Formula Reference operand that is listed under the “Dynamic” section in the Formula editor:
 

Figure 7: Dynamic Formula References

 
The Dynamic Formula Reference operator itself is not designated to return a Numerical, Boolean, Text, or Date result. Once a Dynamic Formula Reference operator is placed into a Formula container, the operator will turn into the respective data type. Then, a list of the available Formula Reference Expressions (matching the respective data type) will be displayed under the Properties tab on the right-hand side of the editor.
 
Please Note: Formulas can also reference Calculated Fields. Currently only one level of reference is supported (i.e. you cannot reference Calculated Fields that reference other Calculated Fields).

Figure 7b: Dynamic Formula Reference data types

Rules of Formula References

1. Incomplete Formulas cannot be referenced.
    
   

   Figure 8a: Formula Reference Rule 1

    

2. You cannot create circular Formula References.
    
   

   Figure 8b: Formula Reference Rule 2

    

3. A Formula Reference cannot be the only component of a Formula.
    
   

   Figure 8c: Formula Reference Rule 3

    

 
Completed Formulas that incorporate Dynamic Formula References may be used to create Calculated Fields. Please note: Once the Calculated Field has been created, any Formula Reference is fully resolved into the Calculated Field and indistinguishable from other Formula components.
 
When the Calculated Field is included on a Form, and configured to “Show Details” (as shown in Figure 9), each individual component of the Formula will be displayed as any prior Formula References have been flattened into the Calculated Field.
 

Figure 9a: Formula showing the Formula Reference

Figure 9b: Calculated Field with a flattened Formula Reference

Figure 9c: Calculated Field as displayed on a Form without any Formula References any longer

Advanced Visibility Rules

If you need to create an advanced visibility rule (see Forms), you first must start by defining a formula with a Boolean result. That formula can then be referenced to create your Advanced Visibility Rule (Fig. 10). Please note that if you change the Formula being referenced after it has been utilized for Advanced Conditional Visibility, you must remove and re-select the formula for the new conditions to take effect.

FAQs

Q: What should I keep in mind when working with Formulas?

A: Please consider the following guidance when working with Formulas:

• Formulas cannot reference another formula.
• The Calculated Fields are dynamic. If any field included in the calculation changes, the Calculated Result field will update accordingly.
• Calculated Fields cannot be read-only (they don’t need to be, as they are calculated based off other form fields).

Q: I am looking for a tutorial on how to get started with Formulas, can you help?

A: Please consider the following instructions as an exercise for your sandbox environment to familiarize yourself with PowerClerk's Formula functionality. With that said, let's get started!

• STEP 1: In your sandbox environment create a form by clicking Program Design >> Forms >> New Form. Name this new form "Calculator".
