I am having some trouble here. I need to extend private function getTierPriceStructure($tierPricePath) in class MagentoCatalogUiDataProviderProductFormModifierAdvancedPricing.

How do I achieve this?

PS: I am trying to add new field in tier_price section of product edit page.

This is what I want to do:

private function getTierPriceStructure($tierPricePath)

{

    //since below line is calling parent's private function, it will throw error.

    $result = $this->getTierPriceStructure($tierPricePath); //this is private function

    $newColumn = [

        'children' => [

            'record' => [

                'children' => [

                    'value_cost' => [

                        'arguments' => [

                            'data' => [

                                'config' => [

                                    'componentType' => Field::NAME,

                                    'formElement' => Input::NAME,

                                    'dataType' => Price::NAME,

                                    'label' => __('Cost'),

                                    'enableLabel' => true,

                                    'dataScope' => 'value_cost',

                                    'addbefore' => $this->locator->getStore()

                                                                 ->getBaseCurrency()

                                                                 ->getCurrencySymbol(),

                                    'sortOrder' => 80,

                                    'validation' => [

                                        'required-entry' => true,

                                        'validate-greater-than-zero' => true,

                                        'validate-number' => true,

                                    ],

                                    'imports' => [

                                        'priceValueCost' => '${ $.provider }:data.product.value_cost',

                                    ],

                                ],

                            ],

                        ],

                    ],

                ],

            ],

        ],

    ];

    $result = $result + $newColumn;



    return $result;
