I have a form that I use to enter a sales quote for a customer. The data is stored in the sales quote table. I am in the process of designing another form from a query that will pull of the of the data from a particular sales quote and turn it into a sales order. My dilemma is the following: Once the sales order is created I want to secure the data in the sales quote table for the particular transaction so that it cannot be changed. Since the quote turned into a sale I do not want the historical info to change. How do I do this?
