Automatically pull up the purchase price

at the start step, add the action "copy process product fields"
Copy From - purchase price
Copy B - purchase price of the process product

Additional problem: a bunch of price categories in the interface settings. Kaa is called the price, which "humanly" is called the Purchase Price.
1. It is this price that should be displayed in the tabular section
2. It is this price that should be saved when it is entered manually in the tabular part and subsequently pulled up automatically.
3. It is this price that should be the base when calculating the cost
