DATEDIFF - Calculate date difference from different tables

Hi, I have two related tables Products and Logs. I need to calculate difference of dates as

Products.Date_Entered and

Logs.Date_modified.

Unfortunately Power BI DATEDIFF does not allow me to use columns from different tables using New Column.

Please suggest me a way to achieve this without using any aggregate function on 1 column.

This is Error "A single value for column 'Date_Entered' in table 'Products' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."

Your earliest response will be highly appreciated.
