Credit order - Error

Hi,

While entering the credit order for non-stock item, at detail level in item number field we have to enter the non stock item code.

I am entering the stock item code instead of non-stock item code, system allowing me to save the order.

Is there any way so that whenever I enter the stock item instead of non-stock item system should throw an error and do not allow to create the credit order with stock item code?

Only allow to create the credit order with non-stock item code.

Is there any functionality exist?

Regards,
