Power BI time functions

[Npg3]

Hi, 

I want to create a function in power bi to creates a new colum and adds a certain amount of time depending on a key word that is a period of time in a different column. 

example:

row 1  includes a date in column A and word in column B ( a word like ATO is 6 months) so when row 1 column B is ATO it adds 6 months onto row 1 column A and the new date is placed in new row 1 column C.

basically the amount of time added onto the row in column A is dependent on word in the corresponding row of column B

Hi @Npg3 

It depends. If not too many text variants and if only number of months to be added then you may try

Column C =
EDATE (
'Table'[Column A],
SWITCH ( 'Table'[Column B], "AOT", 6, "XYZ", 3, "ABC", 1 )
)

[Npg3]

It shows expression.error: the name 'EDATE' wasn't recognized. Make sure it's spelled right

The code is for DAX calculated column not Power Query M language.

How can I create this function in a custom column in power BI?

Hi @Npg3 ,

You can try M Code as below.

Date.AddMonths(
    [Column A],
    if [Column B] = "AOT" then 6 
    else if [Column B] = "XYZ" then 3 
    else if [Column B] = "ABC" then 1 
    else null)

Result is as below.

This works but the problem is if I want column B to have AOT and ABC in one row it does not work. The way the data is pulled in is in some rows of columb B they have multiple (codes). How do I have power bi choose the code with the lowest timeframe. I tried using LOOKUPVALUE but it will not recognize LOOKUPVALUE people have been using power querey for that function which I do not have. Any advice?

You may insert conditional column. Should be straightforward.
