Format Date which is a string / Using a View

[yellow_days]

Hello,

I have a Date column which is a String . I would like to generate a new column, that shows me the last n days. Therefore I need to convert my Column in a date

Im using this code:

Column_NewDate = FORMAT(PIVOT_TABLE[DATES];"DD.MM.YYYY")

I get a new column but as soon I create a new column for the last n days, i get a error msg.

Im using following code:

IF(DATEDIFF(PIVOT_TABLE[Column_NewDate ],TODAY(),DAY)>=7, "Yes", "No")

I get the Error Msg that I can not convert "23.10.2017" of Type "Text" into Date

I dont know what Iam doing wrong. Is it maybe because Iam using a View?

Look at the DATEVALUE function. https://msdn.microsoft.com/en-us/query-bi/dax/datevalue-function-dax

I get the same Error Msg "You cant convert text to date"

I tried following Code:

Test = DATEVALUE(PIVOT_TABLE[DATES])

Maybe I should mention that my text date looks like this: DD.MM.YYYY

Use SUBSTITUTE to replace your "." with "/" before you try DATEVALUE.

Hi,

There could be one of 2 problems.  Either . is not a recognised date seperator in your Windows Installation or if it is, then may be your systems date format in MM/DD/YYYY.  It could also be both reasons.
