Hi @yuhkao ,

Based on my test, the column that related in the relationship should be the same data type even though they are in different format.

But in your Table2, the Date column is whole number type and it cannot be converted to the date type(or be converted to the wrong date). You should check for it first.

Both data type and format should match to use relationships. I always create a DateKey to use as my relationship linkage between tables. You can do this in the Query Editor by adding a custom column and using the formula:
=Date.ToText([Date], "YYYYMMdd")

For your Table 2 you may have to do a bit more cleansing to convert it into a date data type first.
