Change management on ATO Order

Dear All

We have a requirement to change configuration of ATO model (increase/decrease qty or add/delete option) after order is booked. However, when we make such configuration change, the star item gets delinked from sales order and there is no change on downstream IR-ISO/PR-PO/WO. We want to understand if the ATO configuration change can be cascaded to downstream IR-ISO/PR-PO/WO.

Thanks in advance.
