In sales order you can not save a order line, when a new ASI is defined in that line. And (of course) the quantity ist not in stock. This works when no ASI is defined.
The validation makes sense, when the ASI defines a charge/lot. And there is no chance that new products with the same charge/lot will be produced again. But the validation makes no sense, when the ASI defines a attribute like the color. I would like to make the validation configurable with a checkbox for the table M_AttributeSet named "Allow overselling". Also the bug that saving the line with the qty of 0 and then changing the qty is allowed, must be corrected.
