Step by Step Explanation with exact Extract from SAP SuccessFactors Learning documents:

Understanding Sub-Curricula:

Sub-curricula are curricula nested within a main curriculum, allowing complex training structures. Their completion status can impact the main curriculum’s status.

Nested Structure (B):

Sub-curricula are embedded within a main curriculum to organize related training requirements.

Extract from SAP SuccessFactors Learning Documentation (Admin Guide, Curriculum Management):

"A sub-curriculum is a curriculum that is nested within a main curriculum, allowing administrators to group related training requirements under a single curriculum structure."

Impact on Main Curriculum (C):

Changes to the completion status of a sub-curriculum can affect whether the main curriculum is marked as complete.

Extract from SAP SuccessFactors Learning Documentation (Admin Guide, Curriculum Management):

"The completion status of a sub-curriculum contributes to the overall completion status of the main curriculum. If a sub-curriculum is incomplete, the main curriculum may remain incomplete until all requirements are met."

Why Other Options are Incorrect:

Option A (Recurring items have no impact):Recurring items in a sub-curriculum can affect the main curriculum’s status if they are required for completion.

Option D (Incomplete items have no effect):Incomplete items in a sub-curriculum can prevent the main curriculum from being completed.

Conclusion:

Sub-curricula are nested within main curricula (B), and their completion status can affect the main curriculum (C).
