3746231 - Parent–Child Item Hierarchy Restriction In Service Tickets

Incoming message fails with the error:

“Item ABC: The item being assigned as Parent is already a child item.” Note: ABC represents the line item ID.

SAP Cloud for Customer for core applications

When replicating service calls from SAP Field Service Management to SAP Cloud for Customer, the incoming message fails with the mentioned error.

To reproduce directly in C4C:

1. Go to Service Work Center
2. Open any Ticket
3. Navigate to the Items facet
4. Add an item (ABC)
5. Add another item (DEF) and set ABC as its parent
6. Add another item (XYZ) and try to set DEF as its parent

Result :-
Error appears:
“Item XYZ: The item being assigned as Parent is already a child item.”

• By system design, C4C does not allow multi-level hierarchies (grandchild relationships) in items.
• If an item is already assigned as a child (e.g., DEF is a child of ABC), it cannot be assigned as a parent to another item.

1. To avoid such issues, users need to ensure that the incoming payload uses only items without an existing parent as the parent item. Items that are already children cannot be reused as parent items for new entries.
2. This restriction is part of the standard system design for maintaining a single-level parent–child hierarchy.
