Dear ejazahmed4162,

Looks like the mentioned error 'CX_SY_DYN_CALL_ILLEGAL_TYPE' is coming due to SYST-CPROG and SYST-DYNNR fields in the CALL FUNCTION 'F4_FILENAME' statement. Please try using a fixed program name and screen number instead of dynamic fields.

Please edit your post and use the CODE button around your code. It will then be nicely formatted and easier to read and people are more likely to help you.

Don't use those old fashioned FM, better use class CL_GUI_FRONTEND_SERVICES, methods such as FILE_OPEN_DIALOG and GUI_UPLOAD (Use the link to find sap provided samples)
