How does a user get alerted if the entered material in a sales order is not available?

When a user enters a material in a sales order that is not available, the system generates an automatic response to notify the user of this condition. In this case, availability control plays a crucial role in managing stock levels and ensuring that orders can be fulfilled based on real-time inventory data.

When a user is working within the sales order creation process and inputs a material that is unavailable, the availability control screen appears. This screen provides detailed information regarding the quantity available, the quantity confirmed, and any other relevant stock details, allowing the user to comprehend the situation effectively. It gives clarity on what can be fulfilled and what cannot, enabling the user to take appropriate actions, such as adjusting the order quantities or exploring alternatives.

In contrast, the other options may not provide the direct information required for understanding the availability status. The incompletion log relates to required fields in the order that have not been filled out, the highlighting of a schedule line indicates a processing step but lacks any relevant data about material availability, and an error message on the status bar might provide minimal feedback without the contextual details that the availability control screen offers. Therefore, the appearance of the availability control screen is the most effective method for alerting the user about material unavailability in a sales order.
