Does this meet the goal?

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer chokes, but the text of the scenario is the same in each question in this series.

Start of repeated scenario

You are creating reports for a car repair company. You have four datasets in Excel spreadsheets. Four workbook queries load the datasets to a data model. A sample of the data is shown in the Data Sample exhibit.

Data Sample exhibit:

The data model is shown in the Data Model exhibit. (Click the Exhibit button.)

The tables in the model contain the following data:

* DailyRepairs has a log of hours and revenue for each day, workshop, and repair type. Every day, a log entry is created for each workshop, even if no hours or revenue are recorded for that day. Total Hours and Total Revenue column.

* Workshops have a list of all the workshops and the current and previous workshop managers. The format of the Workshop Manager column is always Firstname Lastname. A value of 1 in the IsLatest column indicates that the workshop manager listed in the record is the current workshop manager.

* RepairTypes has a list of all the repair types

* Dates has a list of dates from 2015 to 2018

End of repeated scenario.

When you attempt to create a relationship between DailyRepairs and Workshops, Power Pivot generates the following error message: ''The relationship cannot be created because each column contains duplicate values. Select at least one column that contains only unique values''.

You need to ensure that you can create a valid relationship between the tables.

* Dates has a list of dates from 2015 to 2018

End of repeated scenario.

You create a measure named Average Revenue Per Hour that calculates the average revenue per hour.

You need to populate a cell in a worksheet to display the Average Revenue Per Hour where Repair Type is Engine.

Which Excel formula should you use?

You have the Excel worksheet shown in the exhibit.

You need to transform the data by using Query Editor.

What should you do first?

You have multiple workbook queries that load data from tables in Microsoft Azure SQL Database to a Power Pivot data model.

You discover that new rows were added to the tables in Azure SQL Database.

You need to ensure that the workbook has the new data.
