Hi iwould like to check if there is any function that allows me to take the last 4 char or a String? Or the 1st two char of a String? I require this because i require to have a auto increase product id. Example current productid stops at WA0059. When admin goes to add new product page, WA0060 should be filled into the productid box automatically. THis is to ensure the naming convention is consistent. Any suggestion how to implement this?
