Filter direction isn't valid for this relationship

[dorukturkoglu]

Hi all, I have just created a one-to-one relationship, however by default cross filter is enabled. When I try to change it from 'both' to 'single' I get the above error, would you have any idea how can I fix this

Hello @dorukturkoglu ,

this phrase is from microsoft documentation "The relationship filters in both directions, which is always the case for one-to-one relationships."

check the full documentation https://learn.microsoft.com/en-us/power-bi/guidance/relationships-one-to-one

If I answered your question, please mark my post as solution, Appreciate your Kudos 👍
