Activate rental article
Registering a rental article in ST:4 can not be done before the rental price (PRT) has been set. After the price has been set, the rental article price is ready for activation. You can press F12 to open the action menu where you will find an option called Set to ST:4 (Rental Article). Choose this option to activate the rental article.
Assuming the goods article is in stock, the rental process may be started at this point.
