How to Use the CVAL () Function in Report Custom Columns?

In this tutorial, we will learn how to use the CVAL function to convert string or text-based numeric values into decimal numbers, enabling accurate mathematical calculations in reports.

Accessing the Expression Designer:

• Navigate to the Reporting section.

• Open the Sales Register Detailed Report or any "Report".

• Go to Setup Column Attributes.

• Here, you'll see a list of available columns that can be used to build expressions.

• Click on "Add/Edit Expression Columns" where you can write your expression using predefined functions.

• Before adding the expression to the report, go to Other Settings.

• Ensure the Script Editor is set to VBScript.

• Click Save.

  • Note: VBScript is the default for new configurations but always verify this setting.

Writing Your First Expression

• Every expression must start with the script header: '#@LSCRIPT

• Click the (+) Plus icon to create a new expression.

• Fill in the required fields:

  • Expression Name – A unique name for your expression.

  • Expression Type – Choose either Text or Numeric depending on the expected output.

Creating a Simple CVAL() Expression

• Double-click the new expression name to insert it into the script editor.

• Define the expression using the syntax:

  • Expression Name = CVAL('TOTAL_QTY')

    • CVAL converts the value to a decimal, which can then be used for calculations like sums or averages.

    • Replace 'TOT_QTY' with the string-based field you want to convert (keep the field name in single quotes).

• Save the expression once defined.

• Scroll down and check the box beside the expression name to enable it.

• Save and proceed to check the effect.

• Refresh the report to view the final result.

Output:

With the CVAL function, the system can now treat these as numeric values in totals, filters, or other numeric expressions.
