Question 9
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 choices, 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.
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.
What should you do?
- In the Power Pivot model, change the data type for Workshop[ID] to General
- In the workbook query for Workshops, add an index column
- In the Power Pivot model, change the Table Behavior setting for Workshops
- In the workbook query for Workshops, filter [IsLatest] to equal 1

Which Excel formula should you use?
- =CUBEMEMBER(“ThisWorkbookDataModel”, “[DailyRepairs]. [Avg Revenue Per Hour]”, CUBEMEMBER (“ThisWorkbookDataModel”,“[Dimensions]. [Repair Type]. [Engine]”))
- =CUBEVALUE(“ThisWorkbookDataModel”, “[Measures]. [Avg Revenue Per Hour]”, CUBEMEMBER (“ThisWorkbookDataModel”,“[Dimensions]. [Repair Type]. [Engine]”))
- =CUBEMEMBER(“ThisWorkbookDataModel”, “[DailyRepairs]. [Avg Revenue Per Hour]”, CUBEMEMBER (“ThisWorkbookDataModel”,“[RepairTypes]. [Repair Type]. [Engine]”))
- =CUBEVALUE(“ThisWorkbookDataModel”, “[Measures]. [Avg Revenue Per Hour]”, CUBEMEMBER (“ThisWorkbookDataModel”,“[RepairTypes]. [Repair Type]. [Engine]”))
