代码比较长，请老师见谅！

以下代码用于某一个母卷号的投料量与成材率的DataColChanged运算，进行了修改，使并卷转入后的新钢卷投料量继承了转出的哪些卷的投料量合计数：
If e.DataCol.Name = "审核" AndAlso e.DataRow.RowState <> DataRowState.Detached Then
_dt工序合并表.LoadFilter = "母卷号 = '" & e.DataRow("母卷号") & "' Or 记录标记2 = '" & e.DataRow("记录标记2") & "'"

If drs投料量(0)("工序") = "并卷转入" Then '+++
drs投料量(0)("投料量") = _dt工序合并表.SQLCompute("Sum(投料量)", "工序 = '并卷转出' And 并卷对应卷号 = '" & drs投料量(0)("卷号") & "'") '+++

以下代码是用于全表投料量与成材率计算，主代码也是之前老师帮我写的，但在这里我不会修改了，不知如何修改能实现并卷转入后的新钢卷投料量继承转出的哪些卷的投料量合计数。
