I am new to the forum…
I’d be grateful if someone here could give a solution to this problem.
I must make a communication diagram for the following case.
And after that an activity diagram of the same case.
- The client comes with a product to return it
- The cashier asks from the customer the receipt and he validates it.
- The cashier starts in the register machine a new process for the return of the product
- The cashier inserts the password of the receipt
- The system takes from the store the Info that apply to the given receipt and displays the date and the total price
- The cashier inserts the password of the product (that the customer brought to return)
- The system search the linesale(sale products) and displays it.
5a. The receipt is not valid
1. The system validates that the product hasn’t been purchased before 5 days
2. The cashier tells the customer about the problem and cancels the process
That was all.
It is very important for me. Thanks in advance… Sorry for my English…
