ABAP Command Breakpoints • With the ABAP Cmnds tab, you can set a breakpoint on any of the variety of ABAP statements, shown to you in the F4 Help.

Just Press F4

Conditional Breakpoint • Right click on Breakpoint and choose Create Breakpoint Condition from the context menu(do it when • •

you are in a debugging only). You can use variables in the condition, as well as debugger symbols and functions. Use the Shift+F1 Help on the Breakpoint Condition popup to see the possible condition operands and syntax.

Software Layer Aware Debugging (SLAD) • We can temporarily define layers and jump from layer to layer instead of running though a complex application with small debugger steps. Activate Click on Configure Debugger Layer

Click on Next Object Set

Software Layer Aware Debugging (SLAD) • We can use transaction SLAD to create our own Debugger profile and object set and jump from •

layer to layer or from component to component instead of running though a complex application with small debugger steps. Create Object Set and then profile using transaction SLAD.

Request based Debugging • Go to Utilities Setting Debugging • Set the ID for which Debugging is requested. • Put External break-point at the point where debugger need to be started.

Remote ABAP Debugging(SRDEBUG) • Using SRDEBUG we can easily debug Remote function calls. • Helpful to debug from Portal to R/3 , SRM to R/3 . • To use this option

• Go to transaction SRDEBUG, activate debugging for the -id required. • We can debug with already set External break-points , also we can set break-point for Function modules and Methods.

Check point activation

• Checkpoint group can be used to control, analyse and test the flow of Abap Program • 3 types of checkpoints in ABAP. Break-point, log point and Assert. • Create Checkpoint Group • Go to transaction SAAB , Enter name and click on Create • Enter Description and click on continue • Save the Check point Group and use it in check point statement as shown below

• To activate the check point, go to transaction : SAAB, click on change with checkpoint group name. Navigate to activation tab as shown below.

Check point activation • You can activate the checkpoints for individual s using the button. • Now you can run the ABAP program that has checkpoints in the source. The behavior of the •

checkpoints will be determined by settings that you have defined in the checkpoint group. If you use the Log - Point statement or Assertion statement in log mode, you can open the checkpoint group, navigate to the Log tab, and analyze the log entries that you have created in the ABAP program using the Log – Point statement as shown Below.

Update Task Debugging

• Go into debug mode. Activate update debugging using option setting Change debugger profile • •

click on check box update debugging Ok. Update debugging will be triggered on commit work in another session. Please note one session should be available for update debugger session.

Background Task Debugging • Block TRFC during debug using option setting Change debugger profile click on check box •

TRFC: Block sending  Ok Goto Transaction SM58, select the blocked entry , Choose option Edit Debug LUW

Job Debugging Finished Job • Go to trxn: SM37, select the Job and enter JDBG in command field and click Enter.

Running/Active Job • Select the active job, go to Job Capture Active Job, it will enter into debugging

Tips and Tricks Of Debugging Debugging Endless Loop

• Just use the Process Overview (transaction SM50), select the running process, and choose from the transaction menu Program->Debugging.

Tips and Tricks Of Debugging Debug Popup Windows

• We can debug popup windows by creating an SAP Shortcut file for command /h and dragging this •

into popup window. (Or) Create a text file and write following text into the file. [Function] Command=/H Title=Debugger Type = SystemCommand

Saving Test Data for FM in ABAP Debugger

• In debug mode inside FM , click on tool then click on save parameter as Test data, provide suitable •

name and click Now The test data is saved and now you can access it via test data directory.

Tips and Tricks Of Debugging • Use the difference tool to easily compare variables to see the difference.

Tips and Tricks Of Debugging Handover a debugger Session

• use a debugger variant (menu Debugger->Debugger Session->Save) to store your debugger •

session. Later this session can be ed using Menu Debugger->Debugger Session->Load

Helpful Debugger OK-codes • • • • •

/h activate debugging /hs activate system debugging /ha skip dynpro (PAI, PBO) and directly debug ABAP code /hx detach debugger /hmusa create memory snapshot (can be used in the transaction S_MEMORY_INSPECTOR for memory consumption analysis) • jdbg in SM37 restart of a finished or crashed background job for debugging
