Hi Adithya,
Below is a demo program can be used to upload the Excel data. The program uses the OO methods to do that. plz reward points if it helps.
* Defining Screen Container
DATA: obj_container TYPE REF TO cl_gui_custom_container.
DATA: o_error TYPE REF TO i_oi_error,
o_control TYPE REF TO i_oi_container_control,
o_document TYPE REF TO i_oi_document_proxy,
o_spreadsheet TYPE REF TO i_oi_spreadsheet.
* Data declarations.
DATA: t_files TYPE filetable,
