As listed in the Common Columns section (under Basic Concepts in PPDM), these columns (and others) were shown that they can be automatically populated.  That's great, but how do you use this to your advantage?  Well, one way is to decide how you are going to use the Active_Ind column.  By default, all rows will be populated with a 'Y' and the Effective_Date column will also be populated.  That's great.  

So, what is the business problem that you have?
