Change of default bom of an issue - not changing in multilevel bom related

[F_Lage]

We have an item with a default bom filled with items, lets call them subitems

Subitems have also boms

We modifiied the existing boms by cancelling and duplicate (only way we found to do it)
Then a new default bom is set in those subitems

When we come to the principal item bom and we try to update cost we got an error message asking the old boms from the subitems.

Need some advice to be able to be able to change things in items, boms, etc and the system updating the related documents

Thanks

A search of ‘multi-level bom’ may give you some ideas…

Multi-level BOM with Production Planning Tool

Hello, When creating Bill of Materials, please create Bill of Materials for the sub-assemblies first. The Bill of Material for the finished item should be made in the end. In the finished item’s BOM, with the sub-assembly items, their respective BOM will be selected as well. If BOM is configured as suggested above, then finished item’s BOM will include all the raw materials required, even one’s in the BOM of sub-assembly items. https://frappe.github.io/erpnext/user/manual/en/manufacturing/art…

This correct. The thing is what happens if I change a Bom in the
subassembly items, changing the default one and deleting the old school
ones. I found that the parent Item does not change.
