Hi All,

Case 1: One data provider contains year (2002,2003,2004) ,sales and other data provider contains year ( 2005,2006) ,purchases.

If we apply merge , what is the output of year ,Is it like 2002,2003....2006 ?

Case 2: One data provider contains year (2002,2003,2004) ,sales and other data provider contains year ( 2002,2003,2004) ,purchases.

If we apply merge , what is the output of year ,Is it like 2002,2003,2004 ?
