How to Use the DayName Function in Report Custom Columns?

In this tutorial, we’ll learn how to use the DayName function in expression design to display the day of the week (e.g., Monday, Tuesday) based on a date field such as Bill Date.

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 DayName() Expression

• Double-click your newly created expression to insert it into the script editor.

• Define the expression using the syntax:

  • Expression Name = DAYNAME(CDATE(BILL_DATE))

    • CDate(BILL_DATE) converts the bill date string into a proper date format.

    • DAYNAME(...) returns the full name of the weekday (e.g., Wednesday).

• 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.

Result

You will now see a new column in your report showing the name of the day (Monday, Tuesday, etc.) based on each transaction’s Bill Date.
