How to set a comment (chekin note) by SaveAs of a WTPart per API

Version: Windchill 13.0

Use Case: In our customization, we use the SaveAsHelper class to duplicate some WTPart (and structure) and would like to "tag" the function used by setting a comment on the new WTPart, for example: "created by Copy Machine". Then it would be easier to track whether the SaveAs menu of Windchill was used or if the customization was used.

Description:

I cannot find a mean to set this comment/note on an pass it the the SaveAs function. 

I have tried setting "iterationInfo.note" as attribute in the SaveAsObjectInfo, but without success (nor error message).

 final HashMap<RevisionControlled, AbstractSaveAsObjectInfo> saveAsObjects = new HashMap<>();
 for (WTPart wtPart : partsToCopy) {
 final AutoNumberingHelper helper = new AutoNumberingHelper(containerRef);
 final String newPartNumber = helper.getNumber(wtPart.getTypeDefinitionReference());
 final Map<String, String> ibas = new HashMap<>();
 // checkin Comment I try to set, but this has no visible effect.
 ibas.put("iterationInfo.note", "created by Copy Line & Machines"); 
 final AbstractSaveAsObjectInfo info = new PartSaveAsObjectInfo(newPartNumber, wtPart.getName(), folder,((WTContainer) containerRef.getObject()).getOrganization(), wtPart.getView(), null, ibas);
 saveAsObjects.put(wtPart, info);
 }

 final SaveAsHelper saver = new SaveAsHelper(saveAsObjects, null);
 saver.checkConflicts();
 saver.invokeSaveAsPreActionEvent();
 final Map<RevisionControlled, RevisionControlled> saveAsResult = saver.saveAs();

  Does someone have an Idea how to set the comment on the new object?
