Uploading exel file is not reading all records into internal table

Hello all,

I am fetching data from the excel file and putting into internal table. But I have problem there around 280 records in excel bit I am getting only 100 records in internal table y ?

Every time I run I am getting different number of entries in the internal table some times 0 entries in the table.

I have written below code to get data from excel :

PARAMETERS p_file TYPE  rlgrap-filename OBLIGATORY.

DATA : it_zhpsm TYPE TABLE OF ty_z070_hpsm,
wa_zhpsm TYPE ty_z070_hpsm,
it_type   TYPE truxs_t_text_data.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.

CALL FUNCTION 'F4_FILENAME'
EXPORTING
program_name  = syst-cprog
dynpro_number = syst-dynnr
IMPORTING
file_name     = p_file.

START-OF-SELECTION.


CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP'
EXPORTING
*   I_FIELD_SEPEDDRATOR          =
*   I_LINE_HEADER              =
i_tab_raw_data             = it_type
i_filename                 = p_file
TABLES
i_tab_converted_data       = it_zhpsm
EXCEPTIONS
conversion_failed          = 1
OTHERS                     = 2
.
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

Is there any bug in the above code ? I don’t think so then what is the problem why I am getting different number entries in the internal table every time.

My file contains following records in below attached file
