When the salesperson creates a meeting or direct sales order, they are offered the option of including it in a grouping order.
Once in the sales order edition, the order can be removed from the grouping order.
When the order is finalized, the deliveries and payments proposed will be those set for the order type: direct sale in grouping order or meeting sale in grouping order.
Once an order has been paid for, it can no longer be removed from a grouping order or added to a grouping order.
