Today, while referring to some forums, I came across the procedure (in bits and pieces) to save a XML spec of a Report Studio report to your local disk.
The screen shots below explain the process.
First the lfa.dll file available in Cognosc8bin folder has to be copied to any other folder.
Here, I copied the file to My Projects folder in My Documents folder.
Run the command at the command prompt: regsvr32 lfa.dll This will register the dll file into windows.
