Need to know which method will call for update product

[rvkvino]

I have created custom fields for my product price, I have created the fields in ps_product table and I have created the fields in classes/Product.php. And I have modified view inside the src\PrestaShopBundle\Form\Admin\Product\ProductPrice.php and everything is working fine to display and update the data into database table. But have an issue in while edit data not filled by previously updated. I don't know the exact path where the data get load. I need to know the path and files in which will get the data load. Any one could please help me to know the exact location of file path and how to show the values in edit page. Using prestashop 1.7.5 version currently.
