Comparing two columns in different tables and creating a new table with the difference.

Hi 

 

I have the column Job No in two tables (June & July).

 

I want to compare both the tables and pull out the new job no which are in July's table but not in June.

 

How can I do this in Power BI?

 

Thank You

  • Use Left Anti Join. 

    In July table, insert this statement where Source must be replaced with your previous step name in July table

    = Table.RemoveColumns(Table.NestedJoin(Source, {"Job No"}, June, {"Job No"}, "Temp", JoinKind.LeftAnti), {"Temp"})

    Using DAX.  Create a Calculated Table, and use the DAX EXCEPT Expression.

     

    Expression Name:  EXCEPT

    Description:  Returns the rows of the first table in the expression which do not appear in the second table.

    Syntax:  EXCEPT(<table_expression1>, <table_expression2> 

    Reference URL:  EXCEPT function (DAX) - DAX | Microsoft Learn

     

     

    To produce a delta table where you would like to show what Job Codes appear only in July,

    do the following:

     

    Dax Expression would be:  Jobs only in July = EXCEPT(July,June)
