Employee Work Hours Projection in DAX

This guide details a structured approach using DAX to calculate and project the remaining work hours for employees based on the current week number, including steps for setup and relevant pseudo code for implementation.

Prompt

I have a number of employees that have a set amount of available hours to work each year.  I need to project out how many hours of work they have left in the year based upon the week number of the year.  I have a dates table that for every day, has the week number of the year.  Based upon the week number of the year, I need to project how much hours they have left to work.  How would I do this in DAX?  How do I also get the total number to sum up all the available hours left correctly

Answer

Objective

To project the number of work hours employees have left in the year based on the current week number using DAX.

Steps to Solution

Establish Available Hours Per Employee:
- Ensure each employee has a defined set amount of available hours for the year.
Create the Week Number Context:
- Extract the week number for each day from the dates table.
Calculate Remaining Work Hours:
- Based on the week number, determine how many hours an employee has left to work for the rest of the year.
Summarize the Total Available Hours Left:
- Sum up the available hours left for all employees to get the total projection.

Pseudo Code in DAX

Step 1: Define the Total Available Hours per Employee

Assume you start with a table Employees containing columns EmployeeID, TotalAvailableHours.

Step 2: Create a Dates Table with Week Numbers

Suppose you have a Dates table with columns Date, WeekNumber.

Step 3: Calculate the Remaining Hours per Employee

Create a measure to calculate the remaining hours for an employee based on the current week number.

// Measure to calculate the remaining work hours for an employee
RemainingHours :=
VAR CurrentWeek = MAX(Dates[WeekNumber])
VAR TotalWeeksInYear = 52
VAR TotalHours = MAX(Employees[TotalAvailableHours])
VAR WeeksLeft = TotalWeeksInYear - CurrentWeek
RETURN
    (TotalHours / TotalWeeksInYear) * WeeksLeft

Step 4: Get the Total Sum of Available Hours Left

Create another measure to summarize the remaining hours across all employees.

// Measure to sum up all remaining work hours for all employees
TotalRemainingHours :=
SUMX(Employees, [RemainingHours])

Implementation Notes

Data Model: Ensure that the Employees table and Dates table are correctly related, possibly through a common Date field.
Time Intelligence: Adjust the calculations if the working hours are not evenly distributed throughout the weeks or if there are holidays and other non-working periods to be considered.
Scalability: Ensure that the DAX queries are optimized for performance, especially with large datasets.

Conclusion

The pseudo code provides a structured approach to project the remaining working hours for employees based on the week number of the year. It includes defining total available hours, calculating the remaining hours, and summing them up for all employees, facilitating efficient projection and summarization in DAX.
