Overview

^Top of page

Ensuring optimal performance and stability of your ABAP Cloud-based extensions is crucial to long-term success. Learn techniques and best practices for troubleshooting and optimizing custom code in the Cloud ERP. Use powerful tools like the ABAP Cross Trace to get deep insights into execution flows and resource consumption. This session introduces attendees how to analyze custom extensions in SAP Fiori Apps within ABAP Cloud using tools like ABAP Debugger, Feed Reader, ABAP Cross Trace, ABAP Trace, SQL Trace, Memory Analyzer, Table Comparison Tool.

In the Getting Started section we outline how to logon to the system and to access your package for these exercises. We shortly introduce the Fiori App to use in the exercises.

In Exercise 1 a runtime error occurs for specific input data. With the tool Feed Reader and the ABAP Debugger we examine the root cause. Here a specific case is not handled correctly in a single line of ABAP code.

In Exercise 2 after a change in the ABAP code an Out-Of-Memory error is thrown. This runtime error is usually not related to the call of a single line of code. We analyze with the Memory Inspector the memory consumption and increase.

In Exercise 3 you will then use the ABAP Cross trace for tracing and analysing ABAP Cloud applications across different runtime components. The tool is useful to track down errors or unexpected behavior even without runtime errors.

The focus of Exercise 4 is on performance analysis using the ABAP Trace. There we learn different techniques to improve the runtime in ABAP code. In addition with help of the Table Comparison Tool we analye a functional error introduced with one of our optimizations.

In Exercise 5 we perform a code push down to the HANA Database using CDS views. Here we learn to create an SQL trace and analyze the execution plan in the HANA SQL Analyzer in Visual Studio Code.

So let us start and have a look at the Getting Started section: Getting Started - Mandatory, please check.
