To represent the flow of activities for the use case "Print credit payments report," we need to gather information from the case study about the specific process and data involved in managing credit payments for painters. According to the case study, painters pay to use the FCP system by purchasing credits, which are used to prepare quotes for customers. Payment for credits is handled through PayPal, but FCP keeps a record of these transactions. Each quote costs a certain number of credits, and credits expire after three months. The system notifies painters when they need to purchase more credits or when they have run out of credits. Additionally, FCP provides summary reports each month, which include the revenue from payments for credits, broken down for each capital city. This information will be essential to create the activity diagram for printing the credit payments report, as it involves collecting and summarizing transaction data to generate the report.

Now, let's create an activity diagram for the use case "Print credit payments report":

Start: The process begins when the user $($e$.$g$.,$ Artie Brush$)$ initiates the request to print the credit payments report.

Collect Payment Transactions: The system collects all the credit payment transactions recorded in the database. This includes details such as the amount paid, the date of payment, and the painter's details.

Filter by Time Period: The system filters the transactions based on the specified reporting period $($e$.$g$.,$ monthly$).$

Categorize by City: The system categorizes the payment transactions by the painters' locations, breaking them down by each capital city.

Calculate Totals: The system calculates the total revenue from credit payments for each city.

Generate Report: The system generates a summary report that includes the total revenue from credit payments, broken down by each capital city.

Print Report: The system sends the report to the printer or generates a PDF for digital records.

End: The process ends when the report is successfully printed or saved.

The activity diagram for this use case will visually represent these steps, showing the flow from the initiation of the report request to the printing or saving of the final report.
