Dump GETWA_NOT_ASSIGNED with REUSE_ALV_GRID_DISPLAY

Question

Hi All,
Today I observed that REUSE_ALV_GRID_DISPLAY gives dump GETWA_NOT_ASSIGNED if we pass a blank table for output. These days I am working with ECC6. Earlier when I use to work with ECC5 such thing never happened and ALV get displayed without any row.
Does anyone know is that correct that in ECC6 blank table in REUSE_ALV_GRID_DISPLAY gives dump. If so, any reason why in ECC6 and not in ECC5?
Regards,
Bhaskar

Hi Bhaskar Tripathi ,
I have an example that works in ECC 6 if you want you can compare it with your code.
