Error with oBOM.BOMViews.Item("Structured")

[Alivibro]

I'm using Inventor 2019 with ILogic.  This code has one error in the last line

Dim oDoc As AssemblyDocument
oDoc = ThisApplication.ActiveDocument

' Set a reference to the BOM
Dim oBOM As BOM
oBOM = oDoc.ComponentDefinition.BOM
    
' Set the structured view to 'all levels'
oBOM.StructuredViewFirstLevelOnly = False

' Make sure that the structured view is enabled.
oBOM.StructuredViewEnabled = True

' Set a reference to the "Structured" BOMView
Dim oStructuredBOMView As BOMView
oStructuredBOMView = oBOM.BOMViews.Item("Structured")

and the error is:

System.ArgumentException: Parametro non corretto. (Eccezione da HRESULT: 0x80070057 (E_INVALIDARG))
   in System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
   in Inventor.BOMViews.get_Item(Object Index)
   in ThisRule.Main()
   in Autodesk.iLogic.Exec.AppDomExec.ExecRuleInAssembly(Assembly assem)
   in iLogic.RuleEvalContainer.ExecRuleEval(String execRule)

How can I solve the problem?

Thanks, Luca

Hi, in what language are you using Inventor?
This access error is generally displayed when you have an inventor installed in another language, here I leave you a code that captures the name regardless of the language. I have placed a dialog box with the name for each BomView so you can check it.

Dim oDoc As AssemblyDocument
oDoc = ThisApplication.ActiveDocument

' Set a reference to the BOM
Dim oBOM As BOM
oBOM = oDoc.ComponentDefinition.BOM
    
' Set the structured view to 'all levels'
oBOM.StructuredViewFirstLevelOnly = False

' Make sure that the structured view is enabled.
oBOM.StructuredViewEnabled = True

Dim oBVList As New ArrayList
For Each item As BOMView In oBOM.BOMViews
	oBVList.Add(item.Name)
	MessageBox.Show(item.Name)
Next

Dim BomStructName As String= oBVList(1)

' Set a reference to the "Structured" BOMView
Dim oStructuredBOMView As BOMView
oStructuredBOMView = oBOM.BOMViews.Item(BomStructName)

 The New ArrayList starts counting from number 0, that's why zero will be unnarmed and 1 will represent structured. Once you have found the correct name you can put your name and delete the part of the code that I have passed you. In updated inventor versions you can put an integer for the bomview, such as
oStructuredBOMView = oBOM.BOMViews.Item (2)
But in this case keep in mind that it starts counting from 1 and not from zero as in the new arraylist
In old inventor versions this could not be done

Hope this helps with your problem. Cheers
