Debugging Logic Modules in SAP VIM is rarely straightforward. Setting multiple breakpoints, stepping through code execution, and still failing to reach the relevant section can quickly become frustrating and time-consuming.
However, there’s a little-known approach that can make this process far more efficient.

The Hidden Program That Simplifies Debugging
Within the SAP VIM development packages, there is a program that can be executed via transaction SE38:
/OPT/DR_BPF_TESTThis program does not appear in the standard OpenText documentation, which means many consultants are unaware of its existence. Yet it provides a structured way to analyze and debug Logic Modules.
Key Capabilities
- Display a list of all Logic Modules executed for a given document
- View the sequence of module calls in detail
- Decide whether to simulate the process start, rerun business rules, or both.
- Set a breakpoint in the code and execute the program in SE38 to jump into the debugger without detours
This transforms debugging from a trial-and-error exercise into a transparent, manageable process. Instead of relying on chance to intercept the correct module, you can work systematically through the exact logic that is being applied.
How to use it
- Execute the program in SE38
- Enter the corresponding VIM DP document ID, decide if you want to check the process start, the re-run of business rules or both and decide if you want to show the modules only or process them:
- Benefit from a clean list that gives all relevant information for debugging Logic Modules. You can pick up the class name, set a breakpoint in the code and repeat.
Why This Is Valuable
Effective debugging is essential in every OpenText Vendor Invoice Management for SAP Solutions (VIM) project, whether for customizing workflows, implementing enhancements, or analyzing issues in production support. By providing direct insight into the sequence and behavior of Logic Modules, /OPT/DR_BPF_TEST can significantly reduce the time spent on troubleshooting.
Because this tool is not part of the official documentation, knowledge of it can provide consultants and project teams with a clear advantage when working on complex VIM implementations.
