Limit number of rows in Webi report in SAP BusinessObjects

When working with SAP BusinessObjects Web Intelligence (WebI) reports, you may need to limit the number of rows returned to improve performance and manage data volume effectively. There are several methods to control row limits depending on your data source and requirements.

Universe-Level Row Limits

If you are using a Universe as the data source, you can define row limits at the Universe level using the Universe Design Tool (UDT). Navigate to Universe Parameters ? Controls to set the maximum size of the result set. This approach provides centralized control and applies to all queries using that universe.

Query-Level Row Limits

In the WebI Query panel, you have the option to set limits on rows retrieved for each individual query. This setting is called Max rows retrieved and provides more granular control over data volume.

Multiple Query Considerations

The Max rows retrieved option is linked to each individual query, not with the WebI document as a whole. When your document contains multiple queries, you need to set the Max rows retrieved for each of them separately. This allows for different row limits based on the specific requirements of each query.

Best Practices

When implementing row limits, consider the following ?

• Set appropriate limits based on report requirements and system performance
• Use universe-level limits for consistent policies across all reports
• Apply query-level limits for specific performance optimization needs
• Test different limit values to balance data completeness with performance

Conclusion

Limiting rows in WebI reports can be achieved through universe-level controls or query-specific settings. Choose the appropriate method based on whether you need centralized control or granular query-level customization.
