Item Structure components missing from intercompany AR invoice

Summary:

Kit components missing from intercompany invoices

Content (please ensure you mask any confidential information):

We have created items structures combined with mandatory components (use configurator to automatically explode lines to SO)

Sales orders from business unit A are shipped from warehouse belonging to Business Unit B, therefore triggering standard intercompany sales orders based on transfer price list. We have noticed however that the component items are not being included and missed from the AR invoice.

There is no entry for these component items also in Monitor Financial Orchestration either.

Any advice welcome of what can be the reason in our item/structure set up
