检查LOGO是否存在

If you need to include a (lot of) graphic(s) on a layout, you need to check first if the object exists or this will cause errors when the output is triggered.?
To do this : (example from smartforms)?
- Define a variable 'GV_GRAPHICS_EXIST' in the global variables

- Add the following code to your smartform

data: ls_stxbitmaps like stxbitmaps.

select single * from stxbitmaps

into ls_stxbitmaps

where tdobject = 'GRAPHICS'

and tdname = gv_logo_zpicprod

and tdid = 'BMAP'

and tdbtype = 'BCOL'.

if sy-subrc eq 0.

gv_graphics_exist = 'X'.

endif.
