表达式的函数参数数量不正确 'LookupSet'

Question

我有这个 Loockup 自定义代码：

Function SumLookup(ByVal items As Object()) As Decimal
If items Is Nothing Then
Return Nothing
End If
Dim suma As Decimal = New Decimal()
Dim ct as Integer = New Integer()
suma = 0
ct = 0
For Each item As Object In items
suma += Convert.ToDecimal(item)
ct += 1
Next
If (ct = 0) Then return 0 else return suma 
End Function

现在我想在表达式中使用：

=Code.SumLookup(LookupSet(Fields!sJerarquiaNivel2.Value,Fields!Unidad.Value,Sum(Fields!InventarioSobreVentas.Value, "DS_DataInventarioDosAniosAnterior"))

问题是当我 运行 项目时我得到：

Expression has an incorrect number of parameters for the function 'LookupSet'

我做错了什么？此致

Answer 1

您需要关闭 SUM

末尾的括号

尝试

LookupSet(Fields!sJerarquiaNivel2.Value,Fields!Unidad.Value,Sum(Fields!InventarioSobreVentas.Value), "DS_DataInventarioDosAniosAnterior")
