I need to set up 2 stock level, one per customer group (one for custom and one for wholesale) can someone point me to the right direction plz? Thanks
You cannot change stock level or qty attribute for different Customer Group. Qty has Global scope! You cannot change it from Admin Panel. But you can change Scope of Qty attribute from Global to Website, or, Store-view Level programmatically. If you want to manage two different stock inventory, you could use two different store-views in your magento.
If someone is looking for something similar I menaged this buying this exstension https://www.wyomind.com/advanced-inventory-magento.html It worked really good
