Hi Shu,
If I understand your need, necessarily must change the current program to add a new button, and when it is pressed then call the customized program "Cycle Count".(All this changes in ABAP)
For "Cycle Count" you should create a new Z program, taking care to fit the dimensions of the screen to the RF device.
Once programs are created in abap, you must convert the screens to HTML format
Best regards,
Alejandro López.
