Question

두 개의 열이 있습니다. 하나는 사용자 이름이고 다른 하나는 고유 사용자 각각에 대한 결정입니다. 예를 들어 사용자 이름이 Rohit이고 모든 사용자가 10 % 무작위로 결정한 경우입니다. 행이 사용자 정의가 아니었다면 다시 예 아니오 10 % 동일한 사용자의 모든 행이 NO 인 경우이 행은 열 사용자 만의 고유 한 이름의 10 % 데이터를 제공합니다.

user3598756 당신은 어떤 변경을 할 수 있습니다를 그래서 IF 행 FROM VALUE = 결함 THAN COPY 10 %가 동일한 사용자와 결정을가집니다.

Sub test() 
Dim lr As Long, lr2 As Long, R As Long, ws1 As Worksheet, ws2 As Worksheet, n As Long 
Application.ScreenUpdating = False 
Set ws1 = Sheets("Sheet1") 
Set ws2 = Sheets("Sheet2") 
Sheets(2).Cells.ClearContents 
n = 1 
lr = ws1.Cells(Rows.Count, "D").End(xlUp).Row 
lr2 = ws2.Cells(Rows.Count, "E").End(xlUp).Row 
For R = 2 To lr 


If Range("D" & R).Value = "gadrooa" And Range("E" & R).Value = "NO_DEFECT" Then 
Rows(R).Copy Destination:=ws2.Range("A" & n + 1) 
n = ws2.Cells(Rows.Count, "A").End(xlUp).Row 


End If 
Next R 
Application.ScreenUpdating = True 
End Sub
