DATEADD function does not work well with filter.

Hi Anonymous 

dateadd() is a very tricky function

according https://docs.microsoft.com/en-us/dax/dateadd-function-dax

The result table includes only dates that exist in the dates column.

If the dates in the current context do not form a contiguous interval, the function returns an error.

so, if your data model doesnt ensure continious of dates it's better to use statements like 

Table[Date] + 90

or to create a Calendar Table for more complicated calculations

Anonymous , as explained by az38 you can not use dateadd. He also suggested solution. You can also create a date add like this

New Date = date(year(table[date])+0,month(table[date])+0,day(table[date])+0)

+0 is what you have replace in year , month or date

To add 7 days

New Date = date(year(table[date]),month(table[date]),day(table[date])+7)

To add 7 Months

New Date = date(year(table[date]),month(table[date])+7,day(table[date]))

You can add more than 12 month too
