VAT and CR number validation during order creation.

The system is allowing order creation and submission even when VAT and CR number values are missing. Specifically, the CR number is coming as NULL, but the order is still getting submitted successfully.

Could you please confirm:

• Is there any standard validation available for CR number in Oracle Order Management?
• What is the recommended way to enforce VAT and CR number as mandatory before order submission?

Any guidance would be appreciated.

Thanks.
