How to create and save a new field in admin module in shopware 6?

Hi

I want to create and save a new field in product detail page in Shopware 6.

I don’t want to use the custom fields.

I want to create a new field in the products table and save the value from the admin product edit page.
 
How it is possible?

maybe with entity extension -> Shopware 6: Entity extension

 

this only shows, how to extend the entity.
but the actual question is:
How can i store the value of my new field on click of Save button in the product edit page.

I’m also stuck with the same problem, in your case, were you able to fetch your input text in your backend?
