WhyI’vecreatedFALV
SALV
• You cannot make standard SALV editable
• It happened too often that users wanted a report in display mode, but then
they’ve changed their mind
REUSE
• I don’t like it
• Procedural programming
• Not all cl_gui_alv_grid options are directly available
• I always ended with getting cl_gui_alv_grid object (so why don’t use it directly)
ALV
• Screen and GUI Status has to be created each time, even if you want a simple
full screen report
• Many times I was repeating the same methods when creating output
