What task can be performed using the SQL Performance Tuning Worklist tool (SWLT)?

The SQL Performance Tuning Worklist tool (SWLT) is specifically designed to assist in the analysis and improvement of SQL performance within SAP systems. Combining static ABAP code scans with runtime data from the SQL Monitor is advantageous because it integrates two critical perspectives: the static analysis of the ABAP code and the actual runtime behavior observed during SQL execution.

This combination allows developers and consultants to identify performance bottlenecks more effectively by correlating the code's structure (as determined by static analysis) with the actual performance issues experienced in a live environment. By using runtime data from the SQL Monitor, it becomes possible to see how the queries perform in practice, thus enabling more targeted optimizations.

The other options, while related to performance improvement tasks, do not specifically leverage the capabilities of SWLT in the same way. For instance, creating a graph comparing ABAP code runtimes does not align with the primary utility of the SWLT tool, which is focused more on SQL performance rather than direct ABAP code runtime comparisons. Estimating the new total runtime of optimized code and combining static scans with SQL Trace data also serve different operational needs that are outside SWLT's main functionality.
