title: MDS business rule
body: <p>I am new with MDS, and I have a question about one to many relation mapping in MDS</p>
  
  <p>I have a product, contains descriptions in multiple languages. I have created two entities with derived hierarchy structure: product (P_ID, P_name)and Addtional description(P_ID, P_Name_in_German, P_name_in_English). </p>
  
  <p>Additonal description is a drop down from product table from MDS UI, but I only want to populate info that releated with its same P_ID. How can I achieve that? Can I use business rules here and how it should look like? </p>
