In Brazil POS the user is able to select an employee, who is currently a sales document creator, manually every time while performing a sale. Only employees who are assigned to the current location will be displayed in the employees list in the popup which appears after clicking on the Pay button.
Enable this setting by going to POS Settings -> Configuration -> Sale -> Choose Employee Manually
Let's test the flow:
Step 1. Add any product into the shopping cart
Step 2. Click Pay
Step 3. There is a popup to select the employee who will be a creator of this sale.
