date/time addition

[maxkhan]

Hi Team, I have been given a project to work on that calculates the originial planned duration of a task and the actual time it took to complete the task.

For instance if a task n is planned to take 4 hours and on the day it takes 5 hours, it should be documented.

I have imported everything correctly but would need some help.

So there is not an actual duration column for every task that has been completed. I need to calculate it myself.

I have the columns: ShiftStartTime & ActualStartTimeOffset (This gives the amount of minutes that task started after shift started)

How can I add ShiftStartTime (date/time format) to ActualStartTimeOffSet (minutes, integer value for example, 300 (which Is 5 hours))?

I would then need to subtract ActualEndTime - ActualStartTime which would get the amount of hours it took for the task to be done in only integer value.

Can someone help with how I can do this in powerqueryeditor and by adding new column for the actual start time of a task and then actual time It took?

Hi @maxkhan,
Thank you for reaching out to the Microsoft Fabric Community Forum regarding your issue.

In addition to the helpful response provided by @Omid_Motamedise  ,I kindly suggest adding a custom column using the following query.This may help you obtain the task hours as an integer value:
= Number.RoundDown([ActualDuration])

Hi @maxkhan ,
Thank you for your response. Below is a detailed overview for your reference.
Add a New Column for the Actual Start Time of the Task

• Open Power BI Desktop and load your dataset,In the Power Query Editor go to the Add Column tab
• In dialog box, givea name to the new column . For example, enter ActualStartTime as the column name.
• In the formula area,enter the below code

= [ShiftStartTime] + #duration(0, 0, [ActualStartTimeOffset], 0)

Add a New Column for the Actual Duration of the Task

• Again, go to the Add Column tab. Click on Custom Column, name new column as ActualDuration.
• Use the following formula to calculate the duration in hours

= Duration.TotalHours([ActualEndTime] - [ActualStartTime])

Convert the Duration to an Integer Value

•  Go to the Add Column tab. Click on Custom Column.
• Name the new column as Duration In Integer.
• Use the below query

= Number.RoundDown([ActualDuration])

Hope the steps provided will be helpful in guiding you to create custom columns.If so,

For the first question, add new custom column and use the following formula

DateTime.AddMinutes([ShiftStartTime], [ActualStartTimeOffset])

For the second question add another custome column and use the following formula

Duration.TotalMinutes([ActualEndTime] - [ActualStartTime])

You can do each [DateTime] + #duration(0,0,[OffsetMinutes],0)

How can I do this as a calculated column? So if offset minutes are stored in a diff table than the shift start time, what will my M code will be?
