In the project we came across the challenge to find information within a list of objects in the debugger. in the ALV display you will only see all the objects instances. Using debugger scripts (basics here) you are able to iterate on the internal object table and work with the values. In the second example I will show you how to display object information in an ALV. Using conditional breakpoints helps if there is a loop over all these objects in the #ABAP code. In the first example we will have the same functionality using a script, but in the end this could be much more powerful using more feature of the ABAP language if the conditions are met. I wrote a demo Report that includes two other reports aka debugger scripts at the bottom to use with this report. It is based on the sflight table and should compile on >NW7.10. ( if not just change these fancy modern commands ). The report selects 50 lines of sflight and creates a table of simple POAOs where the data is stored inside the objects only. These objects are defined in the top of the report. One of the mayor issues / security features of debugger scrips is that you can not create them in a non open SAP System. If needed you should integrate them somehow in your Transports manually. Let’s start. 1. Copy the report at the end of the post into your system. 2. Run it and your debugger will stop: 3. Now we switch to the “Script” tab. Here we can do all the scripting. Copy the local class of the first script report below and remove 3 columns of * comments. Pay attention that “Debugger Single Step” is selected an run the script. 4. The debugger stopps within the loop at sy-tabix 27 where the object contains the requested payment_sum. Great! Ok, this is also possible using conditional breakpoints in such a simple scenario. Second Example Let’s make it a bit more complex. Now we want to see all the information of the object before we iterate over them. 5. Run the program again, when the debugger stopps you paste the code of the second local class. Run the script again and you will see an ALV with the listes information of the classes.
