Hi Venkat,
If your product is controlled then you should activate no control check during classification. This will allow the order processing without license.
If you are assigning the ECCN ( in your case its ECL99 - No Lic Req ) you need to have license for same.
In your screenshot you can see that the Lic determination strategy is also applied for same ECCN. NLR lic type has been picked up. You have to create a new licence for ECL99. Or Check if you have existing lic which is expired.
