How can i caculate in BI Publisher rtf templete the number of days between report day and Due date?

Summary:

Hello!

Trying to create a report of Open Receivables Transaction. So i have the column of Due Date (<?DUE_DATE?>) and i'm running the report with parameter of As of Date (

<?AS_OF_DATE?>).

I'm trying to create a column of "Days Late" that will calculate "As of Date" - "Due Date" in order to present to th customer how many days been passed since the due date for each transaction.

Does anyone know what formula can i use for it?
