结转需先加载当年数据，加载与结转代码有冲突，该怎么处理？

此主题相关图片如下：重合.png

代码：

Dim y As Integer = Date.Today.Year

Dim m As Integer = Date.Today.Month

Dim dt1 As New Date(y, 1, 1)

Dim dt2 As New Date(y, m, Date.DaysInMonth(y, m)) \'获取本月的最后一天

Dim Filter As String

Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"

DataTables("外协加工").LoadFilter = Filter

哦，好啦。
