Hi,
There is a report that has a varchar field should show text values, and if NULL, I need it show blank space, and does in disco desktop, but on viewer, the same worksheet shows NULL.

Even I changed in the Tools - Options - Format menu(desktop), it still show NULL on viewer.
why?
please help! thanks!
