Activate External Debugging – Step by Step Approach

Mobile application or Interface calls from a different ERP system, makes traditional debugging difficult if you do not know this simple trick.

If the initial call originates from an outside application such as Fiori or other system or middleware, you can set up an external debug point for investigation.

Step 1- You need to know atleast one piece of code which is getting triggered. /H does not work in this case.

Step 2 – Set up external break points at any executable line. For example, any data declaration statement is not executable.

For example a perform statement is executable. Select the line and click on external breakpoint button.

A success message will confirm that break point is set.

Notice this message also contain the user name. So the difference between external breakpoint is that it is set for a specific user only.

Step 4 – Execute the transaction in the external system and breakpoint will open automatically where it was set. Please note, you should have SAP session open on your machine.

Also note, in some cases, external system calls the SAP system with a fixed user id or technical id. In that case, if you set the external breakpoint with your user id then it will not work. You need to change the id for debugging – read more over here.
