Sql server 仅当上一个度量成员满足特定条件时才显示行

SELECT NON EMPTY {[Measures].[Income]} ON COLUMNS,
{
            SellDate.[year].Members
} ON ROWS
FROM [HD Kawiarnia]

WITH MEMBER [Measures].[MyMeasure] as 
IIF(
([Measures].[Income], [SellDate].[Year].currentmember) 
     <= ([Measures].[Income], [SellDate].[Year].CURRENTMEMBER.PREVMEMBER) 
, NULL, 
[Measures].[Income])

SELECT NON EMPTY {[Measures].[Income]} on COLUMNS
NON EMPTY {[SellDate].[Year].CHILDREN} on ROWS
FROM 
[HD Kawiarnia]

IIF(
（[措施][收入]，[出售日期][年度].当前成员）
