comparing same data for 2 different dates

thank you

i read your blog - it did helped me to find how to compare data for 2 diffrent dates which is what is need.

the problem is that i also need to see the actual data (see the 2 matrix in the picture i sent), and if i use your method , than i cannot use the dates filters to see the actual data since i need to remove the connection between the date tables and the main data table (as you said in your blog - "Please note that we have not performed any join here with the Sales table. All three tables are independent tables.")

again , the main issue is to see metrix data for each dates (2 dates) and next to it, the diffrences.

i hope i was clear enoght .

thank you again.
