BOM Dismantling
7+
===============
8+
9+
This module adds the ability to create a dismantling BOM by reversing a BOM.
10+
11+
12+
Usage
13+
=====
14+
15+
16+
* On BOM form view, click on "Create dismantling BOM" button and it will reverse your BOM.
17+
* In Manufacturing -> Products, there is a new menu "Dismantling".
18+
* In dismantling tree view, you can search by dismantled product.
19+
* On BOM form view, there is a new button "Create Manufacturing Order".
