Hi Everyone,
I have just started to work on Power BI. I am stuck currently.
In the table, if there is a null value for a row, I want to create new rows and copy previous date's data in the rows but not the date. Date's value I want to copy from other column.
Below tables will give the idea of my problem and the output I need.
And the output table I need is as below-
Can someone please help me with this?
Solved! Go to Solution.
let
Source = your_table,
group = Table.Group(
Source, "DateRange",
{{"x", (x) => if x[Date]{0} = null then null else x},
{"Date", (x) => if x[Date]{0} = null then x[DateRange]{0} else x[Date]{0}}}
),
down = Table.FillDown(group, {"x"}),
xpand = Table.ExpandTableColumn(down, "x", {"Transactions"})
in
xpand
let
Source = your_table,
group = Table.Group(
Source, "DateRange",
{{"x", (x) => if x[Date]{0} = null then null else x},
{"Date", (x) => if x[Date]{0} = null then x[DateRange]{0} else x[Date]{0}}}
),
down = Table.FillDown(group, {"x"}),
xpand = Table.ExpandTableColumn(down, "x", {"Transactions"})
in
xpand
Thank you so much @AlienSx . Will try this. But I need to add rows as well. Number of rows to be added depends on number of transactions present for the previous date.
