请问老师如何在高效流水账计算中增加产品和库存组织条件进行计算，用 [产品] and [库存组织] 只能计算一次，在增加产品计算发生错误
Select Case e.DataCol.Name
Case "产品","入库","出库"
Dim dr As DataRow
Dim mr As DataRow = e.DataRow
Dim drs As List(of DataRow)
dr = e.DataTable.Find("[_SortKey] < " & mr("_SortKey") & " And [产品] and [库存组织] = '" & mr("产品") & "'", "[_SortKey] Desc")
'dr = e.DataTable.Find("[_SortKey] < " & mr("_SortKey") & " And [产品] = '" & mr("产品") & "'", "[_SortKey] Desc")
If dr Is Nothing Then
mr("库存") = mr("入库") - mr("出库")
dr = mr
End If
drs = e.DataTable.Select("[_SortKey] >= " & dr("_SortKey") & " And [产品] and [库存组织] = '" & dr("产品") & "'", "[_SortKey]")
'drs = e.DataTable.Select("[_SortKey] >= " & dr("_SortKey") & " And [产品] = '" & dr("产品") & "'", "[_SortKey]")
For i As Integer = 1 To drs.Count - 1
drs(i)("库存") = drs(i-1)("库存") + drs(i)("入库") - drs(i)("出库")
Next
If e.DataCol.Name = "产品" AndAlso e.OldValue IsNot Nothing AndAlso e.OldValue <> e.NewValue Then
dr = e.DataTable.Find("[_SortKey] < " & mr("_SortKey") & " And [产品] and [库存组织] = '" & e.OldValue & "'", "[_SortKey] Desc")
'dr = e.DataTable.Find("[_SortKey] < " & mr("_SortKey") & " And [产品] = '" & e.OldValue & "'", "[_SortKey] Desc")
If dr Is Nothing Then
dr = e.DataTable.Find("[产品] = '" & e.OldValue & "'", "[_SortKey]")
If dr IsNot Nothing Then
dr("库存") = dr("入库") - dr("出库")
End If
End If
If dr IsNot Nothing Then
drs = e.DataTable.Select("[_SortKey] >= " & dr("_SortKey") & " And [产品] and [库存组织] = '" & dr("产品") & "'", "[_SortKey]")
'drs = e.DataTable.Select("[_SortKey] >= " & dr("_SortKey") & " And [产品] = '" & dr("产品") & "'", "[_SortKey]")
For i As Integer = 1 To drs.Count - 1
drs(i)("库存") = drs(i-1)("库存") + drs(i)("入库") - drs(i)("出库")
Next
End If
End If
End Select
