Hi Vracadom
I apologize for any inconvenience caused. I'm sorry but for now we don't have any setting to avoid this situation.
In any case, I can give you an alternative. Go to ATUM settings > Multi-Inventory, and enable this option:
If you enable it, if you write-off the inventories they won't be displayed in Stock Central and within the product.
Maybe this is not the most suitable option for you, but I tell you anyway in case it helps.
Another option is to use custom development to change the performance in Stock Central, but as we don't offer this service you will need to hire a developer.
Best Regards,
Andrea.
