i have a transaction iview for uploading Xcel file to infotypes . I have called the F4_filename fn module ,so that users can select their file name .
CALL FUNCTION 'F4_FILENAME'
program_name = syst-cprog
dynpro_number = syst-dynnr
FIELD_NAME = ' '
file_name = file_path .
In R/3 it's working fine .But if i access it from the Portal .am getting one new page prior to window popup.
"Please Wait . You will be forwaded automatically.
This page had to be included for techinical reasons ."
How to avoid this page in portal .
