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"})

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)
