I am sending you the idea with an example how you can upload data from an EXCEL file into an internal table. I am not sure if you can take data from different sheet in the same EXCEL file. I think that this is not possible (try it )
Upload the data into an internal table, like the way that I am describing in the above:
  DATA: L_MAX_COL_NB TYPE I.
  DATA: l_file_name LIKE RLGRAP-FILENAME.
Just to be sure that is the correct type for the FM.
  l_file_name = P_FILE_NAME.
  L_MAX_COL_NB = 58.  "Maximum nb of colums that the FM can read.
  CALL FUNCTION 'ALSM_EXCEL_TO_INTERNAL_TABLE'
       EXPORTING
            FILENAME                = l_file_name
            I_BEGIN_COL             = 1
            I_BEGIN_ROW             = 2
            I_END_COL               = L_MAX_COL_NB
            I_END_ROW               = 9999
       TABLES
            INTERN                  = PT_EXCEL
       EXCEPTIONS
            INCONSISTENT_PARAMETERS = 1
            UPLOAD_OLE              = 2
            OTHERS                  = 3.
  IF SY-SUBRC <> 0.
  ENDIF.
Now you should upload the data into your own itab. The Function Module will return to you all the an itab
from all fields and columns. Define the structure of the uploading file into SE11 - Data Dictionary. Then read the fieldcatalog of this structure. In the code that I am sending to you, I am insearting an empty line into the internal table and then I am assigning this line into a corresponding field-symbol. Then I am able to change the working area - so and the line of the itab. Propably you could you the statement APPEND INITIAL LINE TO (your_table_name) ASSIGNING <your_field_symbol>, but the example was written in an old SAP version.
  FIELD-SYMBOLS:
                 <F_REC> LIKE WA_UPLOAD_FILE,      "working are of the uploading file
                 <F_FIELD> TYPE ANY.
  DATA: COLUMN_INT TYPE I,
        C_FIELDNAME(30) TYPE C.
  PERFORM GET_FIELDCATOLG TABLES FIELDCAT
                           USING 'ZECO_CHARALAMBOUS_FILE'.
  LOOP AT PT_EXCEL.
    AT NEW ROW.
      ASSIGN WA_UPLOAD_FILE TO <F_REC>.
    ENDAT.
    COLUMN_INT = PT_EXCEL-COL.
    READ TABLE FIELDCAT INTO WA_FIELDCAT INDEX COLUMN_INT.
    CONCATENATE '<F_REC>-' WA_FIELDCAT-FIELDNAME INTO C_FIELDNAME.
    ASSIGN (C_FIELDNAME) TO <F_FIELD>.
    <F_FIELD> = PT_EXCEL-VALUE.
    AT END OF ROW.
      APPEND WA_UPLOAD_FILE TO GT_UPLOAD_FILE.
      CLEAR WA_UPLOAD_FILE.
    ENDAT.
  ENDLOOP.
With Regards
George
