Pierre Smits commented on OFBIZ-5307:
-------------------------------------
This is called Closed-End production run, as you know the expected outcome (the
quantity of end products as per bom). For both discrete and process oriented
manufacturing this is standard functionality.
What I guess you're talking about is being able to define an Open-End
production-run, whereby you know what the inputs are and the expected end
product. But what you don't know upfront is the (expected) quantity to produce.
A good example is waste separation as a manufacturing process. You know what
goes in, e.g. 1 ton of unsorted waste. And you know what come out of the
process as the end product, e.g. rest waste. The other products coming out of
the process are (in current functionality) by-products.
So in order to have Open-End production runs, the improvement should be able to
have users define the BoM without the quantities, and when generating the
production run be able to have a pre-defined output of 0 of the end product
plus be able to add other end products. During the execution of the production
the output of each defined end product must be equal to or greater than 0.
In current, closed-end productions it is not possible to produce more than the
quantity provided when defining the production run.

> Project: OFBiz
> Issue Type: Improvement
> Components: manufacturing
> Affects Versions: SVN trunk
> Reporter: Rupert Howell
> Assignee: Jacques Le Roux
> Priority: Minor
> Labels: bom, breeder, inverted, manufacturing, reverted
> Fix For: SVN trunk
>
>
> Currently the system only allows for 1 product to be made up from multiple
> other products.
> A common process in manufacturing is to either manufacture multiple parts
> from one part (e.g Chop a length of steel that has been ordered in from a
> supplier and manufacture your own washers) or to disassemble a returned
> manufactured item into its components and restock these components.
> The BOM/MRP/ Manufacturing and production run functionality should be changed
> to allow for production runs in both ways (assemble / disassemble)
