Understanding a Conflicting Filter Situation
Hello,
I have a conflicting filter situation that I'm having trouble understanding. I would appreciate any help.
I have a date table, a fact table, and a users table.
Here are the relationships in place:
- The date table has a 1:n relationship with the fact table on a date column.
- The users table has a 1:n relationship with the fact table on a user column.
I'm wanting to filter a display by both the date column from my date table and the user column from my users table. However, ever time I try to filter by the user column from the users table, the date filter empties out. For some reason, I can't filter by both the date and the user (from the users table).
What could be causing this?
Some potential causes I've thought of:
- My users table has relationships with other fact tables and those fact tables also have a relationship with the date table on the date column. Could this be causing issues?
- My users table has some rows that don't have any rows in the fact table. Could this be causing issues?
Thanks for your time.

Anonymous , do you have a bi-directional relationship? If yes, make them single direction. This should not happen in case the date is coming from the date table and the user from the user table in a single direction relationship.

amitchandak , the fact table I am currently working with doesn't have a bi-directional relationship.
However, one of the other fact tables that is connecting to the user and date table does have a bi-directional relationship between the fact and date table. I have found that when I remove the users table relationship to this particular fact table, then I can filter by both the user column and date table.
I don't understand bi-directional relationships enough to understand why this causes a conflict with the filter. I'll have to learn more to understand this.But more importantly, now I need to understand why PowerBI is forcing this one fact table to have a bi-directional relationship with the date table. I am unable to do a single direction relationship for some reason. I will research this, but if you have any thoughts on this, I'm all ears.
Thank you for your quick response and help!-Caleb
