Simulating the data update and debugging a data transfer process request (DTP request) help you to analyze an incorrect DTP request.
In this way you can also simulate a transformation prior to the actual data transfer if you would like to check whether it provides the desired results.
Simple Simulation and Debugging
The simulation request is started. The request is processed synchronously in a dialog process. If you defined breakpoints, you go to the ABAP Debugger.If you defined a breakpoint for the transformation, you can jump directly to the corresponding data in the ABAP source code from the Data section.
The result of the simulation is displayed in the DTP monitor.
Simulation and Debugging in Expert Mode
In addition to setting breakpoints, expert mode enables you to specify selections for simulating the request and for defining the substep after which you want to write to temporary store during the simulation.
The Debug Request screen appears.
When you call the simulation from the DTP monitor, the filter settings that are displayed as initial are copied from the request displayed in the monitor. When you call it from the DTP maintenance, the filter settings displayed as initial are copied from the next "real" request of the DTP.
You can define if and when to write data to temporary storage during processing and set breakpoints at different times.
