 Expression: 

Sum({<[dataset.field1]={'$(=GetFieldSelections([FilterOne]))'},[dataset.Year]={$(v_YEAR_FILTER)}>} [dataset.sales])

v_YEAR_FILTER  is variable which holds expression of unique value. 

v_YEAR_FILTER=Concat(Distinct If(Len(Trim(Aggr(Only({<year={$(=Concat(Distinct Chr(39)&[dataset.Year]&Chr(39),','))}>}year),year))) = 0,Null(),Chr(39)&Aggr(Only({<year={$(=Concat(Distinct Chr(39)&[dataset.Year]&Chr(39),','))}>}year),year)&Chr(39)),',')

QlikSense Casecade/ display only available values based on previous filter selection

 =Aggr(Only({<year={$(=Concat(Distinct Chr(39)&[dataset.Year]&Chr(39),','))}>}year),year)

Num(Sum(Percentage),'#,##0'),

//Num(Sum([Sales]),'$###,##0'),  

))

Use below expression in Show condition of the field. 

 If(GetSelectedCount([Level 1]) > 0 ,$(=SubStringCount(Concat([Level 1],'|'),'Field1')),0)
