… Central

- Created a new query 'Top 5 Consumers' with a normal query type
- Defined query properties: caption, order by, and top number of rows
- Utilized dataitem 'Cust. Ledger Entry' with filters and columns for customer information and sales
- Implemented aggregate function 'Average' for sales
- Organized code with clear variable declarations and trigger sections
- Improved code readability by using descriptive names and proper indentation"
