In Tableau I approached this IF statement below by creating a parameter for each item [More than a week], [Missed this week], [Second Warning] and [First Warning] all as parameter and carried out an IF statement.
In using Power BI I am not sure what the best apporach is and if an IF statement is still applicable.
How can i approach this pleas, any comments assistance would be much appreciated.
IF
[CountDown] < [More than a week] then
'More than a week'
ELSEIF
[CountDown] < [Missed this week] THEN
'Missed this week'
ELSEIF
[CountDown] < [Second Warning] THEN
'Second Warning'
ELSEIF
[CountDown] < [First Warning] THEN
'First Warning'
ELSE
'No Warning'
END
Many Thanks

Hi L,
I hope your parameters are either whole number or decimal number. There is a latest function "what-if" may help.
Test = IF ( [CountDown] < [More than a week Value], "More than a week", IF ( [CountDown] < [Missed this week Value], "Missed this week", IF ( [CountDown] < [Second Warning Value], "Second Warning", IF ( [CountDown] < [First Warning Value], "First Warning", "No Warning" ) ) ) )
1. You can change these parameters dynamically.
2. Only three data types by now.
3. One table for one parameter.

That is not the correct syntax for an if statement, IF statements in DAX look like:
IF([CountDown] < [More than a week], 'More than a week', IF([CountDown] < [Missed this week], 'Missed this week', IF([CountDown] < [Second Warning], 'Second Warning', IF([CountDown] < [First Warning], 'First Warning', 'No Warning' ) ) ) )
That being said, I would go with a SWITCH statement.

Hi Smoupre,
is there any benefit having these items [More than a week], [Missed this week] etc as parameters in Power BI?
Also the if statement seems to be working, but what might be the advantage of a switch over if in this case.
Many Thanks

Developer types always tell me that a switch statement is preferred over an if statement for purposes of readability, logic flow, etc.
