I cannot really find a clear simple answer as to the difference between By-Product and Disassembly Components and when to use each one. It would be helpful if there was a matrix with checkboxes on each describing what they can do.
In general vocabulary terms, By-Product is usually an unitnentional secondary product where disassembly would be parts… but in IFS terms, what is the difference? Are there limitations of one vs the other? Labor / part cost differences? Other?

Typically, disassembly components are part of a disassembly-type structure — i.e., where you disassemble a product and receive these disassembly components into stock using a disassembly-type shop order.
However, you can also include disassembly components in other types of structures. For example, you might remove a component and receive it into stock during a repair, or you might use a manufacturing structure to convert a product from A to B and remove a component during that process that should be received into stock.
A by-product can be produced in any type of process. Examples include scrap metal, sawdust, or slag.
From a system perspective, there are some differences. A disassembly component can have a scrap factor (and be reported as scrapped) and can be serial-tracked. You can also have a control plan inspection against a disassembly component.
if you describe your process I can try to help recommend what is most suitable to use.

Thanks, Bjorn! The last paragraph was very helpful, I’m more concerned with how IFS treats the two processes differently particularly since Disassembly Components is newer (23R1).
For a further explaination of what we’re trying to accomplish:
We buy several various fitting assemblies (bottom left of image) but it’s often taken apart and it’s components are sent to two different manufacturing areas of our plant. Currently when it’s taken apart, it’s happening on the finished good assembly line but we are also curious if it could be a sub process so we could disassemble these in advance and inventory them with the caveat of we don’t want to have to manually manage the creation of disassembly shop orders due to the volume and fitting variability.
Options:
Any thoughts on our options above or others that we didn’t consider are greatly appreciated.
+25You’re right, a disassembly shop order and requisition would need to be manually generated. It is only automatically generated when disassembly is used as part of a remanufacturing process.
I would suggest a setup like your option 2:
The Finished Good would have a BOM containing:
So to produce one finished good, you consume one fitting assembly. In addition to the finished good the shop order will also produce the nut, back and front ferrule.
You can use cost distribution to determine how much of the cost of the fitting assembly and operations that should go to the nut, back and front ferrule relative how much that should go into the finished good.
You can also choose to have the BOM in two levels. Then the body would have the BOM above and the finished good would have a BOM consuming the body.
Thanks for confirming! Always appreciate your insight, Björn. 🏆 We will proceed with additional testing.

Thanks and good luck testing. Please give an update whether it solves the requirements!
