Add Column Comparing Two Date Columns and Returning the Next date in Column 2 from Column 1

‎07-23-2025 09:46 AM

I am customizing my date table for my business. I have built a column containing only the dates we are open. As we are closed on the weekend I have null values for Saturday, Sunday and holiday closures.

 

I need a third column added to my date table containing the current business day if open or if closed, the next day we're open.

 

I have tried Table.Min with little success. I have tried MINX with filters for open_date<> null and open_date>=Date.Date. I keep getting circular reference errors.

 

This is the result I'm looking for. Thank for looking.

You may be able to add the column referencing the [date_open] column and then doing a Table.FillUp() (or Table.FillDown() depending on which way the table is sorted) step to the new column.

Thank you for looking.

 

Table.AddColumn(#"Removed other columns", "result", each Table.FillDown(table name, [date_open]))
 
Result was an error:
Expression.Error: A cyclic reference was encountered during evaluation. 
 
That's the error I've seen a lot so I must be doing something fundamentally off. The table I'm using is the name of the table.

Try doing it in two steps.
Add a column that is just [date_open] and then in the next step fill down that column.
