IF statement with multiple DATEBETWEEN commands - new to DAX!

[jonclay]

Hi everyone

I'm very new to DAX and I'm getting quite a muddle with my DAX code below. What I want to achieve is the FinYear column to show Pre2000 if the date shown in 'dc1'[si_transactiondateofpayments is between 01/09/1900 and 31/08/2000, then show 2001/2002 if the date is between 01/09/2001 and 31/08/2002 and so on.

I know there should be an ELSE NULL type statement in there too (for those dates that don't fall into any of the parameters), but I'm well and truely stuck with the entire statement.

FinYear =

IF(

DATESBETWEEN('dc1'[si_transactiondateofpayment], DATE(01/09/1900),DATE(31/08/2000),

'Pre 2000',

IF(

DATESBETWEEN('dc1'[si_transactiondateofpayment], DATE(01/09/2001),DATE(31/08/2002),

'2001/2002',NULL

)

)))

Any help would be much appreciated!

Thank you
Jon

Do not avoid TI (time-intel) functions but USE THEM IN THE RIGHT CONTEXT. Then you'll be safe.

@jonclay Avoid TI functions if you can. You can do this easily with simple conditions. Also, use SWITCH TRUE instead of nested IF statements. And your DATE parameters are not correct and you want to use BLANK instead of NULL. Oh, and your quotes were wrong. Other than that, solid code. 🙂

FinYear =
  SWITCH(TRUE(),
    'dc1'[si_transactiondateofpayment] >= DATE(1900,1,9) &&
      'dc1'[si_transactiondateofpayment] <= DATE(2000,8,31),"Pre 2000",
    'dc1'[si_transactiondateofpayment] >= DATE(2001,1,9) &&
      'dc1'[si_transactiondateofpayment] <= DATE(2002,8,31),"2001/2002",
    BLANK()
  )
