Layered If Statement with a mix of Dates and Text

[Brett007]

I made a custom column similar to this;

Text or Date = 
If(ISBLANK(Table1[Status], Table1[Step Status],
If(Table1[Status] = "In Progress", Table1[Step Due Date].[Date],

If(Table1[Status] = "C=Complete", Table1[Step Actual Date].[Date],

If(Table1[Status] = "Not Required", "Not Required",
Blank())))))

I receive a error:

Expressions that yield variant data-type cannot be used to define calculated columns. 

I have the column set to text.  I tried MIN( around the dates as well. 

Any ideas of what to try next?

Thanks

Hi, @Brett007 

Please try something like below.

Text or Date = 
If(ISBLANK(Table1[Status], Table1[Step Status],
If(Table1[Status] = "In Progress", format(Table1[Step Due Date].[Date], "ddmmmmyyyy"),

If(Table1[Status] = "C=Complete", format(Table1[Step Actual Date].[Date], "ddmmmmyyyy"),

If(Table1[Status] = "Not Required", "Not Required",
Blank())))))

First, you need to close your ISBLANK parentheses.

Addressing your actual question, you can use the FORMAT function to convert date to whatever format you'd like. For example, FORMAT ( Table1[DueDate], "mm/dd/yy" ) or FORMAT ( Table1[DueDate], "yyyy-mm-dd" ).

This is a good case to use a SWITCH function too.

Text or Date =
SWITCH (
    Table1[Status],
    BLANK (), Table1[Step Status],
    "In Progress", FORMAT ( Table1[Step Due Date], "yyyy-mm-dd" ),
    "C=Complete", FORMAT ( Table1[Step Actual Date], "yyyy-mm-dd" ),
    "Not Required", "Not Required",
    BLANK ()
)
