How to fix 3 decimal no price list
Hello, I sell diesel at petrol stations in Europe thought plastics cards. My clients can obtains discounts if use as payment mode my card. I need trace de discount plan for each client. Normally my discounts can be 0'066, 0,054, 0,042 € per liter. I'm using products modules for record the cards (card tipe 1, card tipe 2). And to trace discounts I'm using price book. The problem is that I only can put two decimals at price list field. I have tried to fix to 3 decimal but I can not do it. Can you explain me how to fix 3 decimal at price list, quotes, invoices, etc... Thank you in advanced. regards Paco
