Accessing the Runtime Analysis Tool (RAT) 
The Runtime Analysis Tool (RAT) helps you determine the origin of the UI elements displayed in your application at runtime.
Prerequisites
Before you can use the Floorplan Manager (FPM) RAT, you must switch on the Web Dynpro Trace Tool. To do this, complete the following steps:
Run the transaction WD_TRACE_TOOL in the ABAP Workbench (transaction SE80).
Choose the Activate for this User button.
In the Selection of Trace Features dialog box, select the WD Component Configuration checkbox, and choose OK.
The message Tracing active for <USERNAME> (30 minutes still) appears.
You can now use the FPM RAT.
Procedure
To access the FPM RAT, complete the following steps:
Run your application.
Right-click on the UI element that interests you, and, in the context menu, choose Technical Help.
Navigate to the FPM tab.
The FPM tab shows various sections containing information related to the selected UI element.
Note
If the FPM tab page is not visible in the context menu, either the RAT is not available for that particular UI element or floorplan, or you have not opened the Web Dynpro Trace Tool application.
