Date Relationship Not Working

I have used the date table multiple times but I am getting stuck with one data set.  I have double checked the date formats but nothing seems to work.  What I want is for the dates from one table to line up with the dates from the date table.

If the data type of the OPEN_TIME column is date/time, it will never match a date in your date table even if the format is date. There are more digits there that you've simply hidden with the formatting. The data types should match. If you need to preserve the time value from OPEN_TIME make a new column that takes only the date value from OPEN_TIME and use that new column in the date table relationship.

I've also had to go into power query to adjust the data type - just changing the date column from date/time to date in the format pane in power bi desktop did not do the trick. I had to go into power query and adjust the type there.

Thanks sooo much... I would have never figured that out.

It sometimes helps to think of relationships as exact lookups. The relationship can be valid but if no exact match can be found it, the relationship won't actually do anything.

I didn't realize that changing the format is just cosmetic and doesn't change the underlying data.

Me neither. I'm about to test this out and see if it works.
