As per my understanding:
Even though by-products themselves do not require routings for standard processing (since they are typically outputs of another part’s manufacturing process), they cannot be used to create interim orders in IFS Cloud.
This is because:
“A structure revision/alternative must be in the Buildable status for the configuration of the inventory part. The part type must not be Remanufactured, Disassembly, or By-Product.”
This means IFS Cloud does not allow interim orders to be created for by-products, regardless of whether a routing exists.
Summary:
By-products are not intended to be built independently; they are generated as part of another product’s routing.
Therefore, IFS Cloud does not support interim order creation for by-products, and the system will throw the error you encountered if attempted.
If the business process requires the by-product to be handled independently (e.g., tracked, stocked, or sold), you may need to:
