Real-time Application level replication

• BW Extractors/CDSViews support
• accessible via ODP/SAPI
• supports incremental data ingestion

Pros

• low-level to high-level data models
• provides business and application logic
• the SAP Runtime license is sufficient
• lower cost of data ingestion, postprocessing, and storage for high-level data (fewer tables and pipelines needed)

Cons

• not suitable for (near) real-time data ingestion
• some legacy BW Extractors might be slow
• once-per-hour data update should be ok for most of the BW Extractors if the data size isn’t really huge
• creates a higher load on the primary SAP system
