How do I get routings to of sub-assemblies to be linked to the top level assembly

Hi ​@AMP,

What you are seeing is standard behavior in IFS and IFS does not automatically roll up sub‑assembly routings into a top‑level shop order.

In IFS Manufacturing:

• Components of sub‑assemblies do roll up to the top‑level shop order (via the product structure)
• Routings do NOT roll up
  ➜ Routings are tied to the produced part of a shop order, not to the structure hierarchy

So when you print Work Instructions for a top‑level shop order:

• ✅ You get components from all sub‑assemblies
• ❌ You only get operations from the routing of the top‑level part

Further IFS cannot sequence or merge routings across parts automatically.

Sequencing (Operation No, Parallel, Sequence) only works:

• Within one routing
• Within one shop order

There is no standard function to:

• Link routing of Sub‑Assembly A
  → into routing of Top‑Assembly B
  → via sequence or operation dependency

Why IFS does not do this automatically (design reason)

IFS must preserve:

• Revision integrity
• Part‑specific operation history
• Accurate costing
• Independent scheduling

Merging routings across parts would:

• Break revision control
• Mix execution history
• Corrupt costing & lead time calculations

This is why IFS keeps structure and routing execution separate by design.

Hope this helps. Let me know your feedback.

Thanks & Regards,
