Ensuring data quality during migrations, ETL processes, or regular reporting cycles is crucial for maintaining the accuracy and integrity of business data. SAP Business Explorer (BEx) allows users to schedule reports that can help validate the data between source systems (e.g., SAP BW) and target systems (e.g., Data Lake). In this blog, we’ll walk through the process of scheduling a BEx report to validate data quality between a source and destination system.
What is a BEx Report?
SAP Business Explorer (BEx) is a comprehensive, web-based reporting and analysis tool that allows users to query, analyze, and visualize data in SAP Business Warehouse (BW). The BEx reports can be scheduled to run automatically and compare datasets between the source and destination systems, which is essential for data quality validation.
Why is data validation important?
Data validation ensures that data transferred between systems is consistent, accurate, and reliable. Whether you’re dealing with a data migration project or regular data synchronization, ensuring data quality between the source and destination is critical for accurate reporting, decision-making, and compliance.
Step-by-Step Guide to Scheduling a BEx Report for Data Validation:
Step 1: Log into the BEx Analyzer
Start by logging into your SAP Business Explorer (BEx) Analyzer. This tool within SAP Business Warehouse (BW) is used to create, execute, and manage reports.
- Navigate to the BEx Analyzer via SAP GUI.
- Log in with your SAP credentials.
- Go to Add-ins to get the login portal of SAP Analyzer
Step 2: Create or use an Existing BEx Query
Suppose you need a customized query to meet specific data validation needs. In that case, you can create a new BEx query using BEx Query Designer before utilizing it as a BEx report for Data Validation.
If a suitable query already exists, you can reuse it for this process. Open the BEx Analyzer, locate the query by its technical name or description, and review its structure to ensure it meets your current data validation requirements. If necessary, you can adjust the filters or selections without creating a new query from scratch.
Step 3: Schedule the BEx Report
Once your newly created query is ready or you have selected the existing query, the next step is to schedule it to run automatically at specific intervals.
- Save the query as a workbook to enable the BEx Broadcaster setting that helps in scheduling of the BEx Report for the data validation.
2. After the workbook is saved, open the workbook and navigate to tools in add-ins for the BEx Broadcaster. And Create the new Setting as per the requirement.
3. Once the new setting is created as per the requirement, then schedule the report at the specified interval for the data validation.
Step 4: Validate Data between Source and Destination
Once the reports are generated and sent to the required system, the next step is to validate the data between the source and destination systems.
- Use the report received via email to compare the data between the source and the transformed data at the destination.
- Use the scheduled BEx reports to compare key figures and characteristics between the two systems. For Example: Total Sales Amount in the source vs. destination.
- If discrepancies are found, document and track them such that can be worked on to avoid this type of issue in the future.
Step 5: Automate the Comparison Process (Optional):
You can also automate the comparison process using a data validation tool or by writing custom scripts in SAP/at the destination to compare the results from the scheduled BEx reports between the source and destination systems.
Benefits of Scheduling BEx Reports for Data Validation:
- Automation: No manual effort is required to compare data between source and destination.
- Consistency: Reports are generated at regular intervals ensuring consistent data quality checks.
- Scalability: The process can handle large datasets over time, making it suitable for complex data validation projects.
- Error Detection: Discrepancies can be identified early, reducing the risk of data quality issues in production environments.
Conclusion:
Scheduling BEx reports in SAP BI is a powerful way to validate data quality between source and destination systems. By automating these reports and comparing key data points, you can ensure that the data migration or synchronization process maintains the integrity of your critical business data. This approach not only saves time but also reduces the risk of errors in your data-driven decision-making process.
