Print ALV grid
Hey, there.
I have an ALV grid report with a push button which updates the table content on the screen (num values at ALV).
The problem is that the printing itself comes out with the previous values.
I'm using the class CL_SALV_TABLE for the ALV.
Probebly the internal table's modification (modify itab from wa_tab) and the object's refreshing (GR_TABLE->REFRESH( )) is not enough.
Does anyone has an idea what's missing ??
Thanls in advance,
Reb
