Is there any user_exit or solution for Tcode: COR1?

Hello,

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 IDES system, My requirement is that when I create a process order, the long text should be filled by specific value automatically.

Now I find some user_exit, for example: EXIT_SAPLCOZV_001, EXIT_SAPLCOZF_003, and so on, but when I create process order using Tcode COR1, these user exit will not be run.

could you please give me some suggestion?or solution???

thank you very much.
