After profiling an ABAP application, which tool do you use to analyze the sequence of procedural unit calls?

The Aggregated Call Tree is the correct choice for analyzing the sequence of procedural unit calls in an ABAP application after profiling. This tool provides a comprehensive overview of how functions and methods are invoked throughout the execution process. It visualizes the hierarchy and relationships between different calls, making it easier for developers to understand the flow of the application and identify performance bottlenecks.

When using the Aggregated Call Tree, you can see which units call which others, the time taken by each unit, and the total time spent in the application, which is crucial for optimization efforts. This detailed breakdown allows ABAP developers to efficiently trace execution paths and optimize the code by rearranging or modifying database accesses and data processing logic.

Other options serve different purposes in performance analysis. Database Accesses focuses on the database calls made during execution, whereas the ABAP Stack provides insights into runtime errors and supply debugging information. The Condensed Hit List gives a summary of the most frequently accessed procedures but does not provide the detailed call sequence that the Aggregated Call Tree does.
