Scenario Overview

In this business scenario we need to update open Opportunities on a daily basis to set a Remaining Business Days field.

We want this Remaining Business Days field to factor in our custom Calendar so that we know how many working days are left. This will provide useful information for reporting and scheduling. 

We will also set up a Schedule that will periodically run this formula over all Open Opportunities to ensure fully updated Opportunities

North52 Decision Suite Solution

The North52 Decision Suite solution works like this:

  • A formula of type Save - Perform Action is created on the Opportunity entity
  • When the Est. Closed Date changes, the formula is triggered
  • The formula checks to see does Est. Closed Date contain data
  • If it does, the formula sets the default Calendar for this formula to be Super Holidays
  • It then calculates the remaining business days using the DiffWorkingDays function
  • The formula then updates the Remaining Business Days field with the result of the calculation

North52 Decision Suite Steps

The following set of steps outline how to create this formula:

Note: you will need to create a new whole number field on the Opportunity entity called Remaining Business Days for this solution.

      • For From Date, enter UtcDate()
      • For To Date, select Est. Close Date
      • Click Generate
  • Click Save
    • Take note of the shortcode, it will be needed for the Schedule

The following set of steps outline how to set up the Schedule:

  • Create a new Schedule
