In the custom program there is a call to the function CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'.
This is part of the main program SAPLSLVC_FULLSCREEN.
Within this program there are Process Before Output ( PBO) and Process After Input modules ( PAI)
When the user double clikcs on the line it takes them to the detail report.
When the back button is pressed in 9001 the flow goes to PAI and then PBO and the double click does not work any more after the user gets back to the initial
screen 9000 for example.
Inputs will be appreciated.
