How can I change the amount awarded to the loyalty card on purchases from a specific group?

Depending on what is set in the RetailVista Settings, the percentage of a purchase from a specific group is assigned to a loyalty card. In Settings -> Loyalty section, it can be set whether saving is done through the classification structure, product categories, cash register groups, or VAT rates. In most situations, saving is done through the product categories. By going to Settings -> Loyalty section, you can set which table is used for saving. Then, in the Administration, the respective table can be selected and the loyalty card percentage can be set for each group.
