Dear Experts,

When we tried to maintain Vendor Based Long-term vendor declarations by using Product Number and Administration unit , I found that product origin and Preference flag are having BLANK information .

Also, subsequent to this I have found that below fields are not populating in Certificate of Origin ..

1. Preference Criteria
2. Country of Origin

Request you advise me how to get these fields populated automatically in Vendor Based long term declaration and Certificate of Origin .
