Walkthrough: Creating a data mash-up by using Power Query

You can use Microsoft Office Excel to analyze data from Microsoft Dynamics AX. You can use tools that are included in Power BI for Office 365 to incorporate data from a variety of data sources from outside Microsoft Dynamics AX for deeper analysis.

In this walkthrough, you will use an OData feed to get Microsoft Dynamics AX data into Excel, and then mash that data with population data from Wikipedia to create a Power View report to gain business insights. Then you can share the report with your organization by using Power BI sites.

Prerequisites 1. Create an OData feed 2. Import the OData feed into Excel 3. Import external data 4. Merge the data 5. Create a calculated column 6. Create a Power View chart 7. Share the report in Power BI sites

Analytics in Microsoft Dynamics AX Microsoft Dynamics AX integration with Power BI for Office 365

Prerequisites

Before you can complete the procedures in this topic, you must make sure that the following prerequisites are in place.

1. Create an OData feed

The Queries node in the AOT has a large collection of pre-built views that you can use to expose data via OData feeds. In this walkthrough, you will use an OData feed based on the custom query CustomerInvoiceLinesTVsonly, which is based on the CustInvoiceSRS query. If your Microsoft Dynamics AX installation already has the document data source based on the CustomerInvoiceLinesTVsonly query, you can skip this procedure.

1. In Microsoft Dynamics AX, click Organization administration > Setup > Document management > Document data sources.

2. Click New.

3. Specify the following values for the new data source:

   Property	Value
   Module	Accounts receivable
   Data source type	Custom query
   Data source name	CustInvoiceSRS After you enter CustInvoiceSRS, the Edit query window will appear. In Range, click Add. In Table, enter Customer invoice lines. In Derived table, enter Customer invoice lines. In Field, enter Item. In Criteria, enter T0004, T005. For the Date field, in Criteria, enter “1/1/2012”..”12/31/2012”. Click OK to close the CustInvoiceSRS Edit query form. Rename the data source to CustomerInvoiceLinesTVsOnly.
   Activated	Select the Activated check box.
   Description	Custom query based on CustInvoiceSRS.

4. Click Close to close the Document data sources form.

2. Import the OData feed into Excel

You can use Excel to consume OData feeds. Power Query is a Power BI for Office 365 component in Excel that helps you discover data that you can import into Excel for modeling purposes. First, you will import Microsoft Dynamics AX data from an OData feed and import only the required data.

1. In Excel, click POWER QUERY > From Other Sources > From OData Feed.

   Note

   You can install Power Query from here.

2. Enter the URL of the OData feed you created in the previous procedure. If you are prompted for credentials, select Windows and continue. The URL is in the following format:

   http://<ServerName>:8101/DynamicsAx/Services/ODataQueryService/
   

   Note

   Note the following:

   • The letters in the URL must be capitalized as shown above. The case is important for PowerBI refresh through the Data Management Gateway.

   • If you open the query service URL in a browser, you will see XML that shows a list of the OData feeds that are available.

3. In Navigator, double click CustomerInvoiceLinesTVsOnly. If you are prompted to select privacy levels, specify your desired privacy level. For this walkthrough, select Public.

4. Filter the data before importing it.

   Task	Instructions
   Isolate transactions in US Dollars	Click the CustInvoiceJour_CurrencyCode column drop-down and select only USD.
   Remove the transactions that are not subject to tax	Click the CustInvoiceTrans_TaxGroup column drop-down and clear No-Tax.
   Remove columns that aren’t needed	Select the CustInvoiceTrans_TaxGroup and CustInvoiceTrans_LineAmount columns. Right-click the selection and then click Remove Other Columns.

5. Click Apply & Close.

3. Import external data

Next, you will import external data that you will use to add additional context to the Microsoft Dynamics AX data.

1. In Excel, click POWER QUERY > Online Search.

2. In the Online Search pane, enter US population by state, and then press Enter.

3. Point to the Wikipedia entry called States and territories – List of U S states and territories by population, and then click Edit.

4. Select the State or territory and Population estimate for July 1, 2013 columns. Right-click the selected columns and then click Remove Other Columns.

5. Right-click Population estimate for July 1, 2013 and then click Rename. Enter Population.

6. Right-click Population, point to Change Type, and then click Number.

7. Click Apply & Close. The data is added to your workbook in a new tab.

8. Click POWER QUERY > Online Search.

9. In the Online Search pane, enter US state abbreviations, and then press Enter.

10. Point to the Wikipedia entry called Table listing U S state abbreviations, and then click Edit.

11. Select the Region_0 and Codes_1 columns. Right-click the selection, and then click Remove Other Columns.

12. Click Apply & Close. The data is added to your workbook in a new tab.

4. Merge the data

You now have data in three tabs. One contains the tax group (state abbreviation) and customer invoice transaction line amount from Microsoft Dynamics AX, one contains the population by state from Wikipedia, and one contains the states and abbreviations. Next you will merge the data so that you can work with all of it in one tab.

1. Click POWER QUERY > Merge.

2. Select CustomerInvoiceLinesTVsOnly from the first drop-down list.

3. Select Table listing U S state abbreviations from the second drop-down list.

4. Select the CustInvoiceTrans_TaxGroup column from the first source and the Codes_1 column from the second source to specify the column to use to join the two sources, and then click OK. If you are prompted to select a privacy level, select Public.

5. Click the drop-down in NewColumn and select Region_0. Codes_1 represents the state abbreviation and is already a column in the spreadsheet, so you don’t need to add it a second time.

6. Edit the column names:

   Column name	Rename to
   CustInvoiceTrans_TaxGroup	StateCode
   CustInvoiceTrans_LineAmount	LineAmount
   NewColumn.Region_0	State

7. Click Apply & Close. The merged data is added to your workbook in a new tab.

8. Click POWER QUERY > Merge.

9. Select Merge1 from the first drop-down list.

10. Select States and territories – List of U S states and territories by population from the second drop-down list.

11. Select the State column from the first source and the State or territory column from the second source to specify the column to use to join the two sources, and then click OK. If you are prompted to select a privacy level, select Public.

12. Click the drop-down in NewColumn and select Population. State or territory represents the state and is already a column in the spreadsheet, so you don’t need to add it a second time.

13. Right-click NewColumn.Population, and then click Rename. Enter Population for the new name.

14. Click Apply & Close. The merged data is added to your workbook in a new tab.

6. Create a Power View chart

Now that you have merged Microsoft Dynamics AX data with population data from Wikipedia and incorporated a calculated column that uses both data sources, you can use Power View to create a chart to gain business insights.

1. In Excel, click INSERT > Power View.

2. In the Power View Fields pane, expand Merge2.

3. Select StateCode, LineAmount, and Population.

4. In FIELDS, in the drop-down for Population, select Average.
