REST API to Update/Revise/Modify The Star Item's Item Structure PIM In Oracle Cloud?

Ability to change one of the component ( in 2nd level of BOM onwards) of the selected configuration in PIM which does not impact the customer facing configuration.

• ‘C’ is one of the configuration that customer selected ( that goes in the star item )
• C as a subassembly has a standard BOM associated with it – C1 and C2
• But supplier replaces C2 with its substitution C2-S
• We want to bring it back in Oracle which in theory should not impact ‘Star item configuration’ as it’s a lower level BOM.
