3784540 - Replication Flow ABAP Integration Performance: Sizing, Optimization Guidance, and Support Scope - SAP Datasphere

One or more of the following symptoms are observed when using Replication Flow in SAP Datasphere:

• The initial load or delta load takes longer than expected or does not complete within the expected processing window.
• Replication throughput is lower than expected.
• The Replication Flow completes successfully without a functional error, but further performance improvement is requested.

• SAP Datasphere
• ABAP-based Source System

There are several factors that influencing Replication Flow performance, for example:

• Available resources in both ABAP system and Datasphere tenant
• Number and size of the replication objects, data volume and record structure
• Network throughput and latency
• Customer-specific throughput and completion-time requirements

As a result, there is no single configuration that provides optimal performance for every landscape.

Performance optimization normally requires interactive analysis, testing, measurement and adjustment. This type of interactive optimization, capacity planning and landscape-specific tuning is a consulting activity. It is distinct from the correction of a reproducible produce defect through a support case.

Nevertheless, the following SAP Note, Documents and Blogs may be helpful:

• 3360905 - SAP Data Intelligence / SAP Datasphere - ABAP Integration - Performance when using RMS / Replication Flows can help to understand technical details of the integration of ABAP-based sources CDS and SLT in Datasphere replication flow and what is influencing the performance of respective data transfer.
• 3784614 - Replication Flow from ODP Sources: Performance Analysis and Support Scope - SAP Datasphere assists ODP scenarios.
• Sizing, Capacity Planning, and Load Balancing for Replication Flows | SAP Help Portal explains capacity planning, load balancing, performance, and related aspects for replication flows.
• 3260185 - ABAP Data Integration - Runtime Parameters (DHBAS_RUNTIME / LTBAS_RUNTIME) provides information about runtime setting parameters for Datasphere ABAP Data Integration which can be used for performance tuning. 
• Below Support Content pages can help to understanding the extraction logic and which configurations can impact the performance:
  • DATA_NOT_READY Troubleshooting in Datasphere Replication Flows | SAP Help Portal
  • Stuck CDS Views | SAP Help Portal
  • Excessive Partition Creation and “Unable to Fetch Initial Data” During Replication Flow Initial Load | SAP Help Portal
• There are also Community Blogs talking about Sizing and Performance:
  • Replication Flow Blog Series Part 4 - Sizing - SAP Community
  • Replication Flow Blog Series Part 7 – Performance - SAP Community

In case further performance tuning is needed, customer can contact SAP Account Executive to request SAP consulting service, which can support this topic.
