Dynamic Measures, Dax using Switch for Escalation Rates, CPI
Hi Community
I am relatively new to DAX - and hoping to get some help on this calculation (before I go back to SQL :) ) I am trying to create a dynamic calculation for Nomincal vs Constant dollars based on multiple rates.
I have 2 main formulas (but is not applying the way I was hoping)
- Step 1 - Find Rates by Category and Year
RateLookup2017 = SWITCH(VALUES('Escalation'[Escalation]),"Material 1", LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 1"),"Material 2",LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 2"),"Material 3",LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 3"),1) - Step 2 - Apply Rates based on Selection of Nominal vs Constant
2017 Dynamic = IF(HASONEFILTER('Escalation'[Escalation]), SWITCH( VALUES('Escalation'[Escalation]), "Constant", CALCULATE(Sum(Data[Amount]),Data[Year] IN {2017} ), "Nominal", [RateLookup2017]*CALCULATE(SUM(Data[Amount]),Data[Year] IN {2017} ) ,BLANK()),Blank())
MdxScript(Model) (14, 238) Calculation error in measure 'Measures 1'[RateLookup2017]: Function 'SWITCH' does not support comparing values of type True/False with values of type Text. Consider using the VALUE or FORMAT function to convert one of the values.OS Version:
Thanks in Advance for any help ( I can email PBIX)
Unfortunatly that didn't work with LOOKUPVALUE() function.......I just went back to IF as a Calculated Column which works fine.
Constant Amount = IF (AND(Data[Category] = "Material 1",Data[Year]=2017), LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 1")*[Amount], IF (AND(Data[Category] = "Material 2",Data[Year]=2017), LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 2")*[Amount], IF (AND(Data[Category] = "Material 3",Data[Year]=2017), LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 3")*[Amount], IF (AND(Data[Category] = "Material 1",Data[Year]=2018), LOOKUPVALUE('Escalation Rates'[2018],'Escalation Rates'[Category],"Material 1")*[Amount], IF (AND(Data[Category] = "Material 2",Data[Year]=2018), LOOKUPVALUE('Escalation Rates'[2018],'Escalation Rates'[Category],"Material 2")*[Amount], IF (AND(Data[Category] = "Material 3",Data[Year]=2018), LOOKUPVALUE('Escalation Rates'[2018],'Escalation Rates'[Category],"Material 3")*[Amount], IF (AND(Data[Category] = "Material 1",Data[Year]=2019), LOOKUPVALUE('Escalation Rates'[2019],'Escalation Rates'[Category],"Material 1")*[Amount], IF (AND(Data[Category] = "Material 2",Data[Year]=2019), LOOKUPVALUE('Escalation Rates'[2019],'Escalation Rates'[Category],"Material 2")*[Amount], IF (AND(Data[Category] = "Material 3",Data[Year]=2019), LOOKUPVALUE('Escalation Rates'[2019],'Escalation Rates'[Category],"Material 3")*[Amount], 0 )))))))))

Jim_brower this DAX seems need attention:
RateLookup2017 = SWITCH(TRUE(), "Material 1", LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 1"), "Material 2", LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 2"), "Material 3", LOOKUPVALUE('Escalation Rates'[2017],'Escalation Rates'[Category],"Material 3"),1)Highlighted above should return True/False value whereas you just have static value.
Thanks - I updated to values - not sure if that is correct.
Jim_brower i guess you updated the measure in original post. Did it worked? It should be fine thou.
