To upload an Excel file into SAP using ABAP, you can follow these steps. This example demonstrates how to use the TEXT_CONVERT_XLS_TO_SAP function module to read data from an Excel file and store it in an internal table.

1. Create a Selection Screen:

   REPORT z_excel_upload.
   
   PARAMETERS: p_file TYPE rlgrap-filename.
   
   DATA: lt_excel TYPE TABLE OF alsmex_tabline,
         lv_file  TYPE string.
   

2. Select the File:

   AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.
     CALL FUNCTION 'F4_FILENAME'
       IMPORTING
         file_name = p_file.
   

3. Read the Excel File:

   START-OF-SELECTION.
     lv_file = p_file.
   
     CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP'
       EXPORTING
         i_line_header        = 'X'
         i_tab_raw_data       = lt_excel
         i_filename           = lv_file
       TABLES
         i_tab_converted_data = lt_excel
       EXCEPTIONS
         conversion_failed    = 1
         OTHERS               = 2.
   
     IF sy-subrc <> 0.
       WRITE: / 'Error in file conversion'.
       EXIT.
     ENDIF.
   

4. Process the Data:

   LOOP AT lt_excel INTO DATA(ls_excel).
     WRITE: / ls_excel-col1, ls_excel-col2, ls_excel-col3.
   ENDLOOP.
   

This code snippet will help you upload an Excel file into SAP and process its data. Make sure to adjust the field names (col1, col2, col3, etc.) according to your Excel file structure.

For more advanced scenarios, you might want to use the CL_FDT_XL_SPREADSHEET class, which provides more flexibility and supports both SAP GUI and WebGUI environments12.
