selecting filtered data from 'REUSE_ALV_GRID_DISPLAY'

Hello All,

I have a need where i need to be able to use a 'select all' logic on a filtered subset of data using the ALV 'REUSE_ALV_GRID_DISPLAY'. I have added the 'Select all' button to the GUI Status and in the I_CALLBACK_USER_COMMAND section of code in my program, but I can't find the filtered subset of data from the report. Please let me know how you have accomplished this.

Thanks.
