VBA Autofilter Sheet Name - excel

Question

When applying the macro auto filter, we would like to make it work on the sheet we are currently working on regardless of the sheet.
ActiveWorkBook.Worksheets("sheetname").Sheet.AutoFilter.Sort.SortFields.Clear
-> I changed to
ActiveSheet.AutoFilter.Sort.SortFields.CLEAR
but it does not work.

Try this:
Dim Nome_Planilha As String
Nome_Planilha = ActiveSheet.Name
ActiveWorkbook.Worksheets(Nome_Planilha).AutoFilter.Sort.SortFields.Clear
ActiveWorkbook.Worksheets(Nome_Planilha).AutoFilter.Sort.SortFields.Add Key:= _
Range("A1:A872"), SortOn:=xlSortOnValues, Order:=xlDescending, DataOption _
:=xlSortNormal
With ActiveWorkbook.Worksheets(Nome_Planilha).AutoFilter.Sort
.Orientation = xlTopToBottom
.Apply
End With
