3706767 - error: composite child object cannot be used as report object in story reports

• An error occurs when attempting to modify "Report Object Configuration Entity" to change "Is Root" to "Yes" and add the "Sub-Domain Schema List." The error message displayed is: "The object type (cust_**************) refers to a composite child object and therefore it cannot be used as report object."
• MDF child objects are not visible in Story Reports, while only the parent object is displayed.
• The issue involves making MDF child objects reportable in Story Reports, where the child object containing custom fields is not displayed.
• Documentation followed includes "Configuring Custom MDF Objects for Reportability Using Story Reports | SAP Help Portal" and "3042974 - Schemas missing in Story - SAP for Me," but the problem persists.

• SF Admin configurations (Admin Center, Provisioning)
