In the context ofOperational Data Provisioning (ODP), theoperational delta queue (ODQ)is a critical component that manages delta records for incremental data extraction. The management of the ODQ depends on the specific ODP context, particularly whether the target system or source system is responsible for maintaining the delta queue.
* ODP_BW (Option A):
* In theODP_BWcontext, theoperational delta queue (ODQ)is managed by thetarget system(SAP BW/4HANA).
* This means that SAP BW/4HANA takes responsibility for tracking and managing delta records, ensuring that only new or changed data is extracted during subsequent loads.
* This approach is commonly used when the source system does not natively support delta management or when the target system needs more control over the delta handling process.
* ODP_SAP (Option B):In theODP_SAPcontext, thesource system(e.g., SAP ERP) manages the operational delta queue. This is the default behavior for SAP source systems, where the source system maintains the delta queue and provides delta records to the target system upon request.
* ODP_CDS (Option C):TheODP_CDScontext is used for extracting data from Core Data Services (CDS) views in SAP HANA or SAP S/4HANA. In this context, delta handling is typically managed by the source system (SAP HANA or S/4HANA) and not the target system.
* ODP_HANA (Option D):TheODP_HANAcontext is used for extracting data from SAP HANA-based sources. Similar to ODP_CDS, delta handling in this context is managed by the source system (SAP HANA) rather than the target system.
* ODP_BW:
* Delta queue is managed by the target system (SAP BW/4HANA).
* Suitable for scenarios where the source system does not support delta management or when the target system requires more control.
* ODP_SAP:
* Delta queue is managed by the source system (e.g., SAP ERP).
* Default context for SAP source systems.
* ODP_CDS and ODP_HANA:
* Delta handling is managed by the source system (SAP HANA or S/4HANA).
