Slicer filter another slicer
Hi NerdFlanders
Power BI can't handle many to many relations, if that is what you are asking. What can you tell about the key-column in DIM1 and DIM2? If they are unique and equivalent, you can make the connection.
Best,

Hi Anonymous ,
the keys are not eqivalent. Imagine you have in the fact table the prices, in dim1 cars and in dim2 the years. So if I choose in dim1 a mercedes it would show years until 1926 and in the table the price for all cars since 1926, but if i choose Tesla it should filter the slicer with the years only until 2003.
Is this somehow possible without bidirectional filtering and joining tables?
especially on a live connection?
NerdFlanders sorry unless i am missing something why is it not possible to do a bi directional relationship from the dims through the fact? dim to dim, that wouldn't make sense, otherwise it would be in one table, it goes via the fact
the other options is to denormalise the whole model NerdFlanders
when you say live connection are you talkign sql server or sql server cubes?
NerdFlanders ah ok firstly can you actually alter relationships in the live connection? last i knew you couldn't
normalising would be summarising all the data into one table using the summarize function but once again, i am not up to date with the latest functionality in a live connection, i know its quite limited, if you need more flexibility and you aren't able to push back your requirement and do it in the source (the cube) then if its an option you might need to go the imported route.
however have you tried your hand at the lookup value function? however it is a bit of hard coding i think
