The order number like is an optional field. It can be applied as an "equal to" statement or a "like" statement.
If an order number is typed and is not ended with a percentage sign (%) the function will regard it as an "equal to" statement. If ended with a percentage (%) the function will regard it as a "like" statement.
If a value is typed in this field it will directly impact on the calculations for Cum Qty Released and Cum Qty Shipped for "Cum Customer Order Demand" since the customer order lines selected to calculate Cum Qty Released and the movements selected to calculate the Cum Qty Shipped will be limited to order lines and movements where the order number is equal to or like the order number entered in this field.
