Answer: Transaction tab is only visible when someone manually harvests the data from the system. This means that the data must be collected and organized manually in order to be seen in the transaction tab. This is a great way to keep track of all the transactions that have taken place in a system, as it provides a clear overview of the data and makes it easy to find specific transactions. Additionally, it is also a great way to ensure accuracy in the data, as it can be double-checked for accuracy before it is used.
