Cascade dates

[datauser_2025]

Hello! 

I am trying to exapnd a target table to cascade the targets down to the weekly level from the monthly level. However, when I do a merge with my date table, it is returning blanks for all weeks that aren't the first of the month. How can I get the target table to expand to the weekly level with the appropriate targets?

Thanks!

Hi @datauser_2025 ,

Thanks for reaching out to us.

Based on your description, you can try filling down after merging.

Here's an example, after merging with the date table, there're blanks.

Select the columns and then fill down.

Hi @datauser_2025 ,

When you do the merge the values will only get pickup for the lines that match, so in this case you get the line for the first of the month filled out.

To achieve what you need you must be sure that your date is sorted by the date column asc so from 1st January to 31st of December, after that go to the columns that are blank and do a fill down that will mark all the values with the above value.
