product accessory

[snooky155]

Hi,

I'm running the latest versions of Joomla and Virtuemart.
I have the following issue for which I do not have an immediate solution.

I have product A and product B. A is the main product, B is an accessory to A.
A can be bought separately and B can be bought separately but they can also be bought together as product AB.
The main issue is the stock. When AB is bought, stock for A and B needs to be decreased with 1.
How can I do this?

To make things even more complicated, I have 6 models of A and 15 colors of B, but I guess I can use multi-variant for that.
Thank you.

Virtuemart core cannot do this.
You need a product customfield plugin for this.
