Is there Method to make Header Text empty for Tcode: COR1?

When we use tcode COR1 to create a process order, there is a long text near by the process order number. Generally, after we create a process order, the long text will be filled by relevant material description in my Production system, My requirement is that when I create a process order, the long text should be Empty or should be filled by specific value automatically.

Please suggest how to do this????

Thanks in Advance
