I need to send a detailed email to notify a customer when any of the following occurs - sales order deleted, item on a sales order is deleted or a quantity or price on an item on a sales order is modified. Can someone please give some pointers on the script to detect these actions. Additionally, I am planning to create a PDF template that will take as input, as saved search to provide all the details of the sales order and the changes. Does this seem to be the right approach? Thanks!
