Connecting SAP Analytics Cloud (SAC) to ECC data is possible, but it can be a bit involved depending on your ECC system's specifics. Here's a breakdown of the process and key considerations:
Prerequisites:
- SAP ECC 6.0 EHP 07 SPS 04 or higher: This is the minimum requirement for connecting SAC to ECC.
- Cloud Connector: This establishes a secure tunnel between your SAP Cloud Platform and your on-premise ECC system.
- SAP Agent: This facilitates communication between the Cloud Connector and your ECC system.
Connection Options:
- Import Connection: This involves importing data from your ECC system into SAC. You can use either:
- InfoSet Queries: These are predefined queries in ECC. However, they can be performance-intensive.
- SAP Queries: Another type of query in ECC, offering similar functionality to InfoSet Queries.
- No Real-time Data: Import connections don't provide live data. You need to schedule data refreshes to keep your SAC data up-to-date.
- Limited to Queries: You're restricted to using InfoSet Queries or SAP Queries as your data source.
- Live Connection (with Embedded BW): If your ECC system runs on HANA, you can leverage the embedded BW within ECC.
- Advantages:
- Real-time Data: Access live data from your ECC system.
- More Data Sources: You can utilize various BW objects and connections, offering more flexibility than import connections.
- Process:
- Create BW queries on your ECC system.
- Connect SAC to these queries using a live connection.
- Advantages:
- Live Connection (with Separate BW): If your ECC system doesn't run on HANA or you prefer a separate BW layer, you can:
- Set up a separate BW system: This can be a dedicated BW system or a BW system that also serves other purposes.
- Create Virtual Providers in BW: These virtual providers connect to your ECC data.
- Connect SAC to BW Queries: Establish a live connection between SAC and the queries built on the virtual providers in your BW system.
Important Considerations:
- Performance: For import connections, optimize your InfoSet Queries or SAP Queries for performance to avoid slow data refreshes.
- Security: Set up appropriate security measures in SAC to control access to your ECC data.
- Data Modeling: Once the data is in SAC, you can utilize SAC's modeling capabilities to transform and prepare your data for analysis and visualization.
Steps for Setting Up an Import Connection:
- Install and configure the Cloud Connector.
- Install and configure the SAP Agent.
- Create an import data connection in SAC.
- Select your ECC system and specify the InfoSet Query or SAP Query.
- Schedule data refreshes to keep your data up-to-date.
For live connections, the process will involve additional steps related to configuring BW and creating queries.
Remember that connecting SAC to ECC can be complex, especially for live connections. If you're unsure about any part of the process, it's best to consult with an SAP expert or refer to the official SAP documentation.
