如何使用DAX在Power BI中执行SQL Windows功能

Question

请问，我如何在DAX中编写下面的代码，以获取4个列，它们代表唯一ID的先前textvalue？我将不胜感激

SELECT DISTINCT 
[UniqueIdentifier] [Prior 2] = LAG([TextColumn], 2) OVER (PARTITION BY [UniqueIdentifier] ORDER BY [NumberIndex])
    , [Prior 1] = LAG([TextColumn], 1) OVER (PARTITION BY [UniqueIdentifier] ORDER BY [NumberIndex])
    , [Next1] = LEAD([TextColumn], 1) OVER (PARTITION BY [UniqueIdentifier] ORDER BY [NumberIndex])
    , [Next2] = LEAD([TextColumn], 2) OVER (PARTITION BY [UniqueIdentifier] ORDER BY [NumberIndex])
