Hi @ericklasimin61 

Here is the simple source code to achieve the requirement. Also, attached video recording for your reference.

  public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
    {
        public delegate void PersistDelegate();
        [PXOverride]
        public void Persist(PersistDelegate del)
        {
            if (Base.Document.Current != null)
            {
                SOLine objSOLine = Base.Transactions.Select().FirstTableItems.ToList().FirstOrDefault(); // To get the First Row from Document Details tab
                Base.Document.Current.OrderDesc = objSOLine.TranDesc;
            }

            del();
        }
    }
