Existing Environment
Contoso, Ltd. is a manufacturing company that produces outdoor equipment Contoso has quarterly
board meetings for which financial analysts manually prepare Microsoft Excel reports, including
profit and loss statements for each of the company's four business units, a company balance sheet,
and net income projections for the next quarter.
Data and Sources
Data for the reports comes from three sources. Detailed revenue, cost and expense data comes from
an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business
Central. The balance sheet data is not related to the profit and loss results, other than they both
relate to dates.
Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint
Online list. Quarterly projections relate to the profit and loss results by using the following shared
dimensions: date, business unit, department, and product category.
Net Income Projection Data
Net income projection data is stored in a SharePoint Online list named Projections in the format
shown in the following table.Questions & Answers PDF P-10
Revenue projections are set at the monthly level and summed to show projections for the quarter.
Balance Sheet Data
The balance sheet data is imported with final balances for each account per month in the format
shown in the following table.
There is always a row for each account for each month in the balance sheet data.
Dynamics 365 Business Central Data
Business Central contains a product catalog that shows how products roll up to product categories,
which roll up to business units. Revenue data is provided at the date and product level. Expense data
is provided at the date and department level.
Business Issues
Historically, it has taken two analysts a week to prepare the reports for the quarterly board meetings.
Also, there is usually at least one issue each quarter where a value in a report is wrong because of a
bad cell reference in an Excel formula. On occasion, there are conflicting results in the reports
because the products and departments that roll up to each business unit are not defined
consistently.
Planned Changes
Contoso plans to automate and standardize the quarterly reporting process by using Microsoft Power
Bl. The company wants to how long it takes to populate reports to less than two days. The companyQuestions & Answers PDF P-11
wants to create common logic for business units, products, and departments to be used across all
reports, including, but not limited, to the quarterly reporting for the board.
Technical Requirements
Contoso wants the reports and datasets refreshed with minimal manual effort
The company wants to provide a single package of reports to the board that contains custom
navigation and links to supplementary information.
Maintenance, including manually updating data and access, must be minimized as much as possible.
