OUTLINE
1. Making the report on Powerbi desktop
2. Publish the report to Powerbi cloud
3. Pin a dashboard in Powerbi cloud
- Making the report on Power BI desktop
What is Powerbi desktop?
Power BI Desktop is a free application you install on your local computer that lets you connect to, transform, and visualize your data. With Power BI Desktop, you can connect to multiple different sources of data, and combine them (often called modeling) into a data model.
What is Power BI service or Power BI cloud?
Power BI cloud runs on the internet and allows for effective access to Power BI reports, dashboards, etc. Most users who work on business intelligence projects use Power BI Desktop to create reports, and then use the Power BI service to share their reports with others.
The supermarket sales report contains three sheets which shows different analysis and visualizations for branch A, B and C of the supermarket.
Sheet 1 report
(i) What is the gross income and gross margin for the three branches?
NOTE : to select a visualization tool in powerbi desktop simple click the right pane which contains different charts, and select the appropriate data fields.
We can use a stack bar chart to visualize the gross income and gross margin for the three branches.
(ii) What is the quantity of product line sold in the three branches?
Clustered column chart is used here.
(iii) What is the customer type, rating, invoice ID, date of payment, type of payment, city of purchase and product purchased per branch?
Pivot table is most suitable for this representation

2. Publish report to Powerbi cloud
Now we can publish this report to Power BI cloud , so we can share with everyone and also pin a dashboard from it.
3. Pin a dashboard in powerbi cloud
We can easily pin a dashboard from the report we published, to see information for just branch A supermarket sales. When the dashboard is clicked , it opens the main report for more information.
CONCLUSION
