Hi,
If you are using GUI_UPLOAD in 4.7 then the file path whatever you are using currently it won't work. Replace the file path like this.
P_FILE LIKE RLGRAP-FILENAME.
DATA: V_FILE TYPE STRING.
V_FILE = P_FILE.
Now take this v_file for function module.Then only it will open the file otherwise you won't get unable to open file error message.
I observerd that you are getting so many fields from the file to the internal table.
