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
Solved! Go to Solution.
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)
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"})
