Bin Inventory issue on Invoices. We're seeing a potential issue on invoices I'm hoping someone may have insight on. We're using advanced bin management. We can apply a billable item to an invoice and save, and it works as expected. However, if we go back in to edit the invoice and resave it, we get a 'Please configure inventory detail for [item]' error. Yet if we go back into the invoice and try to configure inventory detail for the item we can't; the bin(s) no longer are available. It feels as if each save of the invoice NS is trying to remove the billable item from inventory. I disabled all scripts/workflows on the Invoice just in case, but that didn't resolve the issue. Any insight is appreciated.
