Hi Power Bi community
I want to expand my table with a lot more rows depending on values in some of the tabels columns.
I have the following columns:
1. Index (an index column)
2. Interval (a text column with the text "Annually", "Weekly" or "Daily"
3. Startdate (a date column that says when to start)
4. Enddate (a date column that says when to end)
If a row's interval value is Annually I need a row for each year between the start date and the end date
If a row's interval value is Weekly I need a row for each week between the start date and the end date
If a row's interval value is Daily I need a row for each day between the start date and the end date
Can some help me in the right direction?
All help is greatly appreciated.

Hi,
Add a new column
if [Interval]="Annually" then {Date.Year([Startdate])..Date.Year([Enddate])}
else if [Interval]="Weekly" then List.Dates([Startdate], Duration.Days([Enddate]-[Startdate])/7,#duration(7,0,0,0))
else if [Interval]="Daily" then List.Dates([Startdate], Duration.Days([Enddate]-[Startdate]),#duration(1,0,0,0))
else null)Stéphane
