Table to add discount rates for accounts (customers) to be used in a sales "muniment"

From the account, we choose the customers folder, all customer accounts will appear in the table, and then the percentage is recorded in the table of the discount rate. This discount percentage will be used at the level of the discount rate in the sales "muniment" and on all items

Note: The price table is left blank if the barcode price is used

Note: The option to use account discount must be activated in the "muniment" properties (sales) to activate the discount
