Whenever we wants to debug a program, function module, Web Dynpro application or any other object from external interface (other than GUI) like portal, web dynpro etc, we need to use external break-point. These are function keys, which are used to control debugging ex: go to next break-point, execute perform/function module which out going into it etc.F5 - When you press F5 in debugging, you will go to next step means you program control goes to next line.į6 - When you press F6 in debugging, it will execute the module without going into it.F6 works for performs (subroutines), Function modules, Class methods etc.Įx for F6: we have a program, we have some function modules in the program, when we click F5 in debugging control will go into function module source code, we don`t want to go into function module, in that case we use F6, it will not go into function module instead it will execute it in one step.F7 - When you press F7 in debugging, it will completes the current module/program in a single step.Įx for F7: We have a program, we have a function module in the program, we have put break point, when we press F7 it will completes the program if the control is in program, when we press F7 it will complete the module( FM) when the control is in function module.į8 - When you press F8 in debugging, control will go to next break point if any or completes the program execution. What are uses of F5, F6, F7 and F8 in debugging ? Now, we will learn and understand the real techniques of debugging. Now go to 'Desktop 3', which is friendly to see run-time variables and data, double click on any variable to see respected value and data in right pane. Now execute the program, provide input ex: FERT and execute (F8), breakpoint will trigger. Go to program source code, put cursor where you wants to set break-point and click on set/delete external break-point icon (see image below).

Go to SE38, create a program ZSAPN_DEBUG, and add below code Working with static break point.Go to SE38, create a program ZSAPN_DEBUGGING, add below code and activate.Save, activate and execute the program. When we put break-point in some ABAP code, control will stop at the specific place when executing the ABAP program, then it is debugging mode.We can control debugging using function keys F5, F6, F7 and F8 or using toolbar buttons in debugging screen. In this lesson we will discuss the behavior of breakpoints in each. These breakpoints have different behaviors in different types of coding blocks ex: Function Modules, Sub-routines etc. Session break-point: This break-point will be activated for call only within SAP system and its active till the User session is on.E.g.
Dynamic breakpoints can be set in active (activated) source code only.Dynamic breakpoints are of two types. These breakpoints will be deleted automatically when you log-off from SAP. We need to delete these breakpoints manually.ĭynamic Breakpoints: These breakpoints are user specific, these will trigger for specific user only. Static Breakpoints: These can be set by using statement BREAK-POINT in ABAP code, these breakpoints are not user specific, these will trigger for every user. In SAP Programming there are two kinds of breakpoints.
