To make it very simple, we will create a brand new table (Tab50105.NewTable.al) with a few fields in it: 

table 50105 "NewTable"
{
    DataClassification = ToBeClassified;
   fields
     {

          }
      }
}

Then, we create a table extension (Tab-Ext50105.NewTableExtension.al) that extends the...
