Market share issue - Distribution over a single year

[JaouadZrhibi]

Hi,

I have tried different measures but I cant see the distribution over a single year.

My formula calculate the market share for all years from 2001 till 2018 but how to do it for only one year ?

one year for one direction (import or export) = 100% market share 

Market Share Import = DIVIDE(CALCULATE(SUM([Tons]));CALCULATE(SUM([Tons]);ALL('Details'); Table[Column] = "Import")) 

Market Share Export = DIVIDE(CALCULATE(SUM([Tons]));CALCULATE(SUM([Tons]);ALL('Details'); Table[Column] = "Export")) 

OR 

Market Share = DIVIDE ( CALCULATE ( SUM ( [Tons] ) ), CALCULATE ( SUM ( [Tons] ), VALUES ( Details[Direction] ), ALL ( Details ) ) )
