Cannot we upload more than 10K records to internal table from excel multiple sheets data in sap abap

Hi Experts,

Read multiple sheets of an Excel file into SAP through ABAP - Code Gallery - SCN Wiki

Please check above link, i have written logic based on above link for uploading data from multiple excel sheets  to internal table. But the problem is the below internal table(I_DATA-ROW) row length is 4-Char. so the excel file sheet data is uploading only 9999 records  to internal table (I_DATA). But as per  my Excel per sheet more than 40K-Records has to upload to internal table. So anybody help me on this which is best way to achieve this functionality.

CALL METHOD iref_spreadsheet->get_ranges_data

        EXPORTING

          no_flush  = ''

          all       = ''

*        updating  = -1

*        rangesdef =

        IMPORTING

        contents  = i_data

          error     = iref_error

*        retcode   =

        CHANGING

          ranges    = i_ranges

Thanks
