Error in rule when changing BOM Structure to Phantom

[caspar.boetchiaerAYLML]

Hi 

As title mentions, I get the following error when changing BOM structure to Phantom.

Referenced and Default(Normal) works just fine.

Can anybody help me?

System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)

at Autodesk.iLogic.Exec.AppDomExec.ExecRuleInAssembly(Assembly assem)
at iLogic.RuleEvalContainer.ExecRuleEval(String execRule)

oCompDef = ThisDoc.Document.ComponentDefinition
Dim CheckValue1 As String = "MC-"

For Each oOcc As ComponentOccurrence In oCompDef.Occurrences
	If oOcc.Visible = True And Not oOcc.Name.Contains(CheckValue1) Then
			oOcc.BOMStructure = BOMStructureEnum.kDefaultBOMStructure
	ElseIf oOcc.Visible = True AndAlso oOcc.Name.Contains(CheckValue1) Then
			oOcc.BOMStructure = BOMStructureEnum.kPhantomBOMStructure
			
	Else
		oOcc.BOMStructure = BOMStructureEnum.kReferenceBOMStructure
	End If
Next

The Phantom enumerator of BOM is not accessible through the occurrence object. When you access the BOM Structure from Occurrence you can only change between reference and default. Default is the state you have set in your BOM (it could be phantom or purchased etc.). It is similar when you right click on an occurrence in your assembly and set BOM Strucutre, where you only see two options default and reference. If you set phantom to one of your parts and then check again by right clicking you will see, Default (Phantom).

You need to iterate through actual BOM of the assembly component definition and construct your logic if you want to access Phantom enumerator. Something like below.

Dim oDoc As AssemblyDocument = ThisApplication.ActiveDocument
Dim oDef As AssemblyComponentDefinition = oDoc.ComponentDefinition

Dim oBOM As BOM = oDef.BOM
Dim oBView As BOMView = oBOM.BOMViews.Item(1)

For Each oRow As BOMRow In oBView.BOMRows
	oRow.BOMStructure = BOMStructureEnum.kPhantomBOMStructure
Next

I hope this will help you.

it's because you cant change occurrence bom structure to phantom

and as far as i undertand you want to change part's bom structure not ocurrences? :

check this thread:

Thanks for the Reply.
The suggestion list, showing on your second picture, how is that turned on?

Thanks Dutt.

It's actually your code Im adding to.

So its fitting you're the one who gives the solution.

Ended up using another snippet I had in my notes only because it required less changes.

Here is final versions which seem to work as intented.

oCompDef = ThisDoc.Document.ComponentDefinition


For Each oOcc As ComponentOccurrence In oCompDef.Occurrences
	If oOcc.Visible = True 
			oOcc.BOMStructure = BOMStructureEnum.kDefaultBOMStructure
				
	Else
		oOcc.BOMStructure = BOMStructureEnum.kReferenceBOMStructure
	End If
Next

Dim CheckValue1 As String = "MC-"

Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = ThisApplication.ActiveDocument.ComponentDefinition

'Iterate through all of the occurrences
Dim oOccurrence As ComponentOccurrence
For Each oOccurrence In oAsmCompDef.Occurrences
	If oOccurrence.Name.Contains(CheckValue1) Then
		'set BOM Structure
		oOccurrence.Definition.BOMStructure = BOMStructureEnum.kPhantomBOMStructure 'Phantom 
	End If
	
Next

it was from vba not ilogic but you can get it in ilogic as well, but you must write word BOMStructureEnum first:
