Create a dynpro 0100 for the program as follows:
- add custom container named GC_HTML_VIEWER
- add flow logic as follows:
PROCESS BEFORE OUTPUT.
MODULE create_viewer .
*
PROCESS AFTER INPUT.
MODULE user_command.
Finally, create a GUI status named SIMPLE, with nothing but EXIT, BACK and CANC functions enabled:
Activate everything and program should run. Then create a report transaction for it and test it under ICF services.
cheers
