Visualize and analyze the data

You are a Power BI report creator for a non-profit organization. You have a semantic model with a 'Donations' fact table (columns: 'DonationID', 'DonorID', 'Date', 'Amount', 'CampaignID') and a 'Donors' dimension table (columns: 'DonorID', 'DonorName', 'City', 'DonorType' (Individual/Corporate)).

You are a Power BI developer for a retail company. You have a semantic model that includes a 'Sales' fact table with columns: 'Date', 'ProductID', 'StoreID', 'Quantity', 'UnitPrice'. The 'Product' dimension table includes 'ProductID', 'ProductName', 'Category', 'SubCategory'. The 'Store' dimension table includes 'StoreID', 'StoreName', 'Region', 'District'. You need to create a report page that allows users to analyze sales performance by product category and store region. The report must include a matrix visual with: - Rows: Product Category - Columns: Store Region - Values: Total Sales Amount (Quantity * UnitPrice) Additionally, users must be able to drill down from category to subcategory in the rows, and from region to district in the columns. You also need to ensure that when a user selects a specific store region, the matrix only shows data for that region and its districts. You have created the measures and the matrix visual. However, when you test the drill down, the hierarchy does not work as expected: clicking the expand icon on a category does not show subcategories. What is the most likely cause?
