Unpublished product appear in the store!!?

Hi,

we work with an ERP System in the background. In the area inventory method "track inventory", Minimum stock qty = "1" and "Unpublished" at low stock activity are activated.
An interface put values into Stock quantity.
If the Stock quantity is set to "0", the product is nevertheless available in the shop, only "not in stock" appears.
I've test it with a non admin user.
Is there any adjustment possible, to let the shop act like entries in the product.
If there is nothing, we can do with settings - is a manual way existent, where the products really are unpublished?
When both not possible, is someone able to program this very important feature in our shop?

Our main problem is, that we will run several shops and one leading ERP-System with the complete stock quantity.
So if a product sold in one shop, it's very important, that it will be unpublished in the other shops after a several minutes. This was realized in this moment, only the shop don't work in this way.

regards

Development needed. :)

You didn't mention which version you are using, nor are the details of ERP product updates known.

But NOP settings will unpublish products with these settings enabled:

Inventory method:          Track Inventory
Stock Quantity:            (Actual number is here - test with 1 to see how this works)
Minimum Stock Quantity:    1
Low Stock Availability:    Unpublish
Backorders:                No backorders

Test by purchasing your product.  When the stock goes under minimum allowed quantity, product unpublishes

If you are adding products and/or quantities from your ERP system they must be published to show.  If quantity decrements occur to the product, whether in one or more stores, and the minimum is hit, this product will unpublish.  If you are using separate stores, and not the multi-store within NOP, then of course you would need additional programming.

But for straight up product publication in a multi-store environment, NOP will handle just fine.
