“Make Maintenance Aware” doesn't create underlying structure

Hi, My customer manufactured a Serial Tracked Inventory Parts in their factory (with shop order.)

And if checked with  “Part Serial” screen , you can see the underling structure.

Then, before shipping , they want to maintainace it with work order,

so we created a “Serial Object” with “Make Maintenance Aware” screen.

But when we check the “Equipment Object Navigator” just find that underling structure is NOT created automatially.

is there anyway to make IFS create underling structure?

(we are using APP10 UPD10)
