Hi

is there a pre-defined folder or location where you have to download the report to,

then you can compare using the string.

Instead of validating path , u can give F4 help for that
 
PARAMETERS:p_file LIKE rlgrap-filename.
data : v_file type string.
 
 
*Input Help for the Download Directory
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.
 
  CALL FUNCTION 'F4_FILENAME'
       EXPORTING
            program_name  = v_repid
            dynpro_number = syst-dynnr
            field_name    = 'P_FILE'
       IMPORTING
            file_name     = p_file.
 
v_filename = p_file.
