Delivery Block

Hi,

Since the orders are to be entered by the regions, it is proposed that the sales order is created with the default delivery block which blocks delivery confirmation when the order is created. Therefore, the order will initially have no confirmation schedule lines.

HO user will run a report to find out the list of blocked orders, and replace the delivery block with another block which allows confirmation but blocks actual delivery. This block is important for making sure that all the documentation like road permit is in place before the delivery is made.

This is my requirement.

Can someone suggest me how to cope up with this requirement?
