Having a problem which may be as much a methodology issue as a technical one.
i have a scenario where i use key tables to filter 2 data tables simulateously.
[Data table1]*----1[key table]1----*[Data table2]
There are many 'key tables'.
The problem i am having is i want the key tables to filter based on other key tables selections
For example i wouldnt want to see every Regionin the world in my 'keyRegion' table if i am (in a different filter) only looking at clientX in using the KeyClient table.
I know if i had one table i could simply create fitlers from this, but with two tables i cant figure it out.
i know with one table i can use a star schema method and cross filtering, but with multiple data tables i cannot do this.
im half way to setting up a whole series of key tables that filter each other or using the DAX method here LINK
OR..more likely..i may be askign something that should never be an issue and i need to reevaluate from the bottom up.
Any advice would be appreciated!
This is effectively a many to many pattern. Have a read of my article here explaining how to push a filter from one data table onto anoher lookup table. The examples are not quite the same, but the principle is.
Thanks for the link, i have been reading it.
Has this scenario come about (in my case) from poor design, or is it something fairly typical?
Im trying to get my head around the above.
I can filter using my key tables, it just means the end user has to scroll through lots of fields that arent necessary.
i will attempt to work through your article. I admit i struggle with 'Calculate' but also know i need to get more famililar with it
