DAX with Lookup

[Anonymous]

Hello All,

I have to replicate an Excel formula in POWER BI 

I have 2 tables 

Unit_Table

UNIT NUMBER	Equipment Age	LTD USAGE	M&R %
R07320	15.6	182,996	295%
R05214	19.5	103,401	218%
R06318	17.8	101,181	200%
R06316	17.8	98,367	122%

Lookup table

Modeling Parameters:	Age	LTD	%M&R
(See Input Parameter Spreadsheet)
Weights	0.50	0.2	0.3
Proposed Replacement Cycle	12.00
Utilization Threshold		120000

the Excel Formula i need to replicate is life =(1-Equipment Age(unit_table)/{Lookup table-> Proposed replacement cycle-->age})*100

for Unit Number life should be (1-15.6/12.00)*100 = -29.67

UNIT NUMBER	Equipment Age	LTD USAGE	M&R %	life
R07320	15.6	182,996	295%	-29.67
R05214	19.5	103,401	218%	-62.26
R06318	17.8	101,181	200%	-48.71
R06316	17.8	98,367	122%	-48.55

Thanks

Hi @Anonymous ,

Please try this column:

life = 
VAR _age = CALCULATE(MAX('Lookup table'[Age]),FILTER(ALL('Lookup table'),'Lookup table'[Modeling Parameters:]="Proposed Replacement Cycle"))
VAR _result = (1-DIVIDE('Unit_Table'[Equipment Age],_age))*100
RETURN
_result
