Sharing objects is a common requirement in SAP Data Fabric and SAP BW/4HANA environments to ensure reusability, consistency, and efficiency. Below is a detailed explanation of why the correct answers are A, B, and D:
Correct: Sharing a product dimension view across multiple fact models is a typical use case in data modeling. By reusing the same dimension view, you ensure consistency in how product-related attributes (e.g., product name, category, or hierarchy) are represented across different business segments. This approach avoids redundancy and ensures uniformity in reporting and analytics.
Option A: A product dimension view should be used in different fact models for different business segments
Correct: Time characteristics, such as fiscal year, calendar year, or week, are often reused across multiple DataStore objects (DSOs) in SAP BW/4HANA. Sharing a single time characteristic ensures that all DSOs use the same time-related definitions, which is critical for accurate time-based analysis and reporting.
Option B: A BW time characteristic should be used across multiple DataStore objects (advanced)
Incorrect: While source connections can technically be reused in different replication flows, this is not considered a primary use case for "sharing an object" in the context of SAP Data Fabric. Source connections are typically managed at the system level rather than being shared as reusable objects within the data model.
Option C: A source connection needs to be used in different replication flows
Correct: Centralized time tables are often created in a shared or central space to ensure consistency across different spaces or workspaces in SAP DataSphere. By sharing these tables, you avoid duplicating time-related data and ensure that all dependent models use the same time definitions.
Option D: Time tables are defined in a central space should be used in many other spaces
Incorrect: While remote tables in the SAP BW bridge space can be accessed across SAP DataSphere core spaces, this is more about cross-space access rather than "sharing an object" in the traditional sense. The focus here is on connectivity rather than reusability.
Option E: Use remote tables located in the SAP BW bridge space across SAP DataSphere core spaces
