Check if ItemId is serialized

Hi folks!

Recently I've had a task in which I need to change visibility of particular button if Item number was serialized.
I found a way how to identify it by checking InventTrans statusReceipt.
But after that my colleague advised to me a way with checking Tracking Dimension Group and now I wanted to share this approach with you, guys!
Maybe it will be useful for someone in future.
Code below:

private boolean checkItemSerialized(ItemId _itemId)
{
    EcoResTrackingDimensionGroupItem        trackingDimensionGroupItem;
    EcoResTrackingDimensionGroup            trackingDimensionGroup;
    boolean ret;
    ;
    trackingDimensionGroupItem  = EcoResTrackingDimensionGroupItem::findByItem(curext(), _itemId);
    trackingDimensionGroup      = EcoResTrackingDimensionGroup::find(trackingDimensionGroupItem.TrackingDimensionGroup);
    if (trackingDimensionGroup.Name == #DimSerial)
    {
        ret = true;
    }
    return ret;
}
