In a maintenance plan, what is used to determine the items in a call object?

In a maintenance plan, acall object(e.g., a service order) is generated based on scheduling. Theitemsin this call object—such as spare parts or services—are determined by abill of material (BOM)(Option D).

A BOM with usage type "4" (Plant Maintenance) or "S" (S4 Service) defines the components (materials or services) required for the maintenance task. When the maintenance plan triggers a call, the system references the BOM assigned to the technical object (e.g., equipment or functional location) or task list to populate the call object’s items.

Product bundle (A):Used for grouping products, not for maintenance plan items.

Service order template (B):Defines a structure for service orders but is not linked to maintenance plan scheduling.

Product proposal (C):Suggests items based on rules, not a source for call object items.
