Hello,

Task: [MRP] allow disassembling through manufacturing orders

In the Manufacturing Order, allow to use negative quantities in the Product Quantity field so that the selected product is dismantled and individual components are put back into inventory, with all appropriate stock moves.

More details on pad:

Thanks,
TTA
