When I add Vendor Invoice for Product "ABC" shouldn't it add Buying Price for "ABC" directly?

Dear @eldy,

Thank you for the response.
What I am looking to understand is that the if the reciprocal is also true.
So that when we enter vendor invoice for Vendor V, will it add buying price for Product P?
This way, it is all in sync, so that we don’t have to individually add buying prices. This way, whenever we enter the invoice, it add the buying price as well.

We are interested in this behavior for two reasons.

  1. We have more than 2K products, adding buying price individually is a pain. (When we make a purchase, the prices might have changed as well. So going back to changing that again is also a little difficult to maintain. If we get it in sync, we won’t have to worry about it.)

  2. We have selling price that is dependent on the buying price. We have customized it to work that way through a developer. So now, we need to maintain the buying prices for this main reason. And this would help us a lot.

Can you guide us on how to get this done?
