Making a column based of repeating data for a group of rows baes on the response of one of the rows

[CHealy]

I am trying to make one column(date by group) all the same date based on a grouping. This is a survey based data set and I would like to a column where the date is the response date for the specific Grouped Column (Grouped column is an individual survey). There are to many questions to be able to pivot and unpivot the data. I am also trying to avoid making an additional table andlinking them based on the grouped column. Any Help would be amazing

Hi @CHealy ,

1. In the power query editor, copy an original table.

2. Group and get the response date for each group.

3. perform a merge query on the two tables.

4. expand table2.
