A disassembly component is a component derived from the disassembly process of a product. Disassembly components can be added to below structure types:
A disassembly component is technically included in the Bill of Material (BOM) of the main product with a negative quantity per assembly. In IFS/Manufacturing Standards disassembly components are defined with a positive quantity per assembly separately from the components on the Produced Parts tab on the Product Structure and Configuration Structure pages. When a shop order is created for the main part, disassembly components are copied to the Shop Order/Produced Parts tab according to the selected structure revision and alternate.
Disassembly components can be connected to the operation where they are produced and should be received to stock. If not connected, the system assumes it is produced and received in the last routing step.
IFS/Dynamic Order Processing (DOP) does not support the use of disassembly components.
By selecting the Use as Supply in MRP option for the given disassembly component, it can be defined as a supply to be used in planning engines like MS and MRP. Furthermore, by enabling Use as Supply in MRP, planning engines will use that component supply for future demands that comes for the part which was defined as a disassembly component.
After creating the shop order from the shop order requisition (created for the parent part), by enabling or disabling the Use as Supply in MRP option the planner has the option to consider using the disassembly component supply from the shop order in the next MRP/MS run. By default the Use as Supply in MRP option is getting the enabled status from the structure disassembly component line.
Note: A part cannot be added as a produced part (by-product,
co-product, or disassembly component) if it is already a parent to the main
product. For example, if the produced part has a structure and the main
product is already defined as a component or produced part at a lower level,
you cannot add the part as a produced part unless the Stop BOM
Explosion toggle is enabled in the produced part line of the
structure.
When adding such a part with the Stop BOM Explosion
option enabled, it is crucial to proceed with caution, especially
if the Use as Supply in MRP option is also being used.
One approach is to leave the Use as Supply in MRP option
disabled in the produced part line of the structure and manually enable it
after creating the shop order from a shop order requisition.
Alternatively, if both the Use as Supply in MRP and
Stop BOM Explosion options are enabled, the planning engines will
still identify the produced part supply. However, there may be instances
where the produced part supply generated from supply proposals of planning
engines includes a part that has already been processed in the MRP execution.
Consequently, this planned supply will not be included in the netting
process. Unnetted Planned Supply MS/MRP action message can
be used to identify when such occurrences happen.
The valuation of manufactured products can be determined by using cost distribution factors. The cost distribution factors provide a means of distributing costs of materials, operations and general overhead cost between the main product and the additionally produced parts (by-products, co-products and disassembly components). When not using cost distribution, the valuation of the main product is determined by removing the standard cost of the additionally produced parts from the sum of the material, operation, and general overhead costs.
