From an SAP BW/4HANA perspective, what is the difference between SAP HANA Smart Data Access (SDA) and SAP HANA Smart Data Integration (SDI)? Note: There are 2 correct answers to this question

Question

Options

• ASDI provides options for data replication in real-time, while SDA does NOT provide this capability.
• BSAP BW/4HANA Data Sources of source system type "SAP HANA Smart Data Access
• CSAP BW/4HANA Open ODS Views can be modelled on SDI sources, but NOT on SDA sources
• DSDA is integrated into the SAP HANA Index server while you need to set up an additional SAP

• A
  81% (17)
• B
  10% (2)
• C
  10% (2)

Explanation

A is correct because SDI (Smart Data Integration) supports real-time data replication through its Data Provisioning Adapters, enabling continuous data movement from source to target - a capability SDA fundamentally lacks since it only provides virtual/federated read access to remote data without physically moving it.

D is correct because SDA is natively embedded in the SAP HANA Index Server, requiring no extra installation, while SDI requires a separately installed and configured Data Provisioning Agent (DP Agent) to function - hence "set up an additional SAP..." component.

B is wrong because BW/4HANA Data Sources can be created on SDA sources; SDA is a valid source system type in BW/4HANA. C is wrong because Open ODS Views in BW/4HANA can be modeled on both SDA and SDI sources - not SDI exclusively.

Memory tip: Think of the contrast as "SDA = Simple, Built-in, Read-only" vs "SDI = Separate Agent, Dynamic Replication". If a question mentions real-time replication → SDI; if it mentions no extra setup needed → SDA.
