In the Personal Range of prouducts you need to have the Home & Business version (not Personal Plus - next product up). They are called "TAGS" not classes but same thing. If you have tags set up you can find the list under TOOLS menu.
Tell me about tagging transactions
Tags provide an additional way of classifying transactions in Reckon Accounts.
For example, you can use tags to group transactions for a specific event such as a vacation. Just create a tag called vacation, and tag all the applicable transactions accordingly. Later, to see the total cost of your vacation, you can customise a report such as the transaction report to include transactions with the vacation tag.
If you purchased Reckon Accounts Home & Business, Reckon Accounts includes a specialised type of tag called a business tag. Business tags show you the income, expense, and deduction information for a business. See how tags work with businesses for more information.What can I do with tags?
Is there something else you want to do?
Is there a maximum you can add to the security type? When I tried to add a new one recently, there was message saying"All security type in use". And I could not add any more.
