Tracking overall stock/inventory by the gram

[Sean Kelley]

I've been using VM 2.0.20b on a variety of projects for awhile now and am very familiar with it.  However I currently have a project that requires a slightly different type of inventory tracking system.

It's for a herbal supplement company and they want to be able to track overall inventory of a given herbal remedy by gram.  For example, they are selling their "Ginkgo" product in a variety of sizes: by the gram, by 1/8 oz. (7.5 grams), 1/4 oz. (15 grams) and 12 oz. (30 grams).

They want to be able to define their overall inventory (say, 5000g).  Then whenever a customer orders a particular size (e.g. "1/4 oz., 15 grams") the overall inventory level is reduced accordingly: i.e. 5000g - 15g = 4985g.

I know how to set up child products and cart variants but it doesn't seem like those tools would really apply here.  Am I missing something?  How can I set up the type of inventory tracking I described above.  Is VM even capable of this?

Thanks!

In next version of Virtuemart there is a ability to choose the step of adding to cart current product.
In your case it's necessary to have choosable steps for each product (drop down box near add-to-cart-button):
1 grams
7.5 grams
15 grams
30 grams
I could imagine that each variant in this drop down box could be written with the own alias, like this:
by the gram
by 1/8 oz. (7.5 grams)
1/4 oz. (15 grams)
12 oz. (30 grams)

So VM inventory will become gram inventory then.

Thanks for your response.

I recall that in VM 1 there was the option to add custom "quantity steps" to a product.  So you're saying that in VM 2 does not currently have this ability?  And there is no other way to achieve what I'm looking to do with VM 2?

So you're saying that in VM 2 does not currently have this ability?

I said "next version" has this feature.

Current version is, as we all know, 2.0.20b.

BUT you could find on virtuemart.net more newer version.

Maxim,

When is the next release of VM scheduled?  I.e. the version that will contain this feature?

Thanx, for your question, Sean Kelley.

It seems that it's not so simply task to see more newer version of Virtuemart on virtuemart.net.
