C4C Enhancing Quote Product Item with Embeded Component

Hi All,

I am enhancing Sales Quote Product Item with customer BO using EC following the guide Add custom BO to standards screen

provided by Stefan Krauth see below for detailed explanation how I created the BO and EC.

For some reason whenever I change the item it is not triggering the UIID change, from my perspective some initialization is missing but I am not sure how should I do it.

Thanks in advance.

Here is my BODL:

businessobject ProductVariant {
[AlternativeKey][Label("Varinat Identificator")] element variantID:ID;      //NUMC 10"
[AlternativeKey][Label("Quotation Item UUID")] element QuoteItemUUID:UUID;
[Label("Product Id")] element productID:apCommonGDT:ProductInternalID;
association ToMaterial[1,1] to Material;
node Characteristics [0,n]{                [Label("Internal characteristic")] element atinnInternalCharacteristics:ID; //NUMC  10                            [Label("Characteristic Name")] element atnamCharacteristicsName:LANGUAGEINDEPENDENT_MEDIUM_Text; //CHAR             30                            node CharacteristicValues [0,n]{                                [Label("Internal characteristic")] element atinnInternalCharacteristics:ID; //NUMC 10                                             [Label("Int counter")] element atzhlInternalCharacteristics:BusinessTransactionDocumentItemScheduleLineID;//NUMC 4                                [Label("Characteristic Value")] element atwrtCharacteristicsValue:LANGUAGEINDEPENDENT_MEDIUM_Text;//CHAR 30                                [Label("Characteristic value description")] element atwtbCharacteristicsDescription:MEDIUM_Name;//CHAR 30                }
}
}               

The screen looks like
