( DISTRIBUTION =  HASH ([Process_Key]))  
AS SELECT   
                      A.[PROCKEY] AS 'Process_Key',  
                      A.[LOCATION] AS 'Location',

                      COUNT_BIG(*) AS 'TOTALCOUNT'  
  
                      FROM [PLTG_STG].[ABC] A                                                                            
                      
                        INNER JOIN  
  
             [PLTG_STG].[ZEN] B  
            ON  A.[LOCATION] =  B.[LOCATION]  
            GROUP BY   
            A.[PROCKEY],A.[LOCATION],A.[INDICATOR],B.[SALESITEM] ;
