Create dynamic internal table

[Former Member]

Hi,

I am creating a dynamic internal table which has 164 columns. 34 columns (Sales area)repeating 4 times.I am able to form a field catelao, but the method CALL METHOD cl_alv_table_create=>create_dynamic_table gives the short dump 'LOAD_PROGRAM_NOT_FOUND' Program " " not found.

here is my code:

FORM get_dynamic_table .

DATA:

my_data TYPE ty_general_data,

my_data1 TYPE ty_sales,

descr_ref TYPE ref to cl_abap_structdescr,

descr_ref1 TYPE ref to cl_abap_structdescr.

FIELD-SYMBOLS:

<comp_wa> TYPE abap_compdescr.

descr_ref ?= cl_abap_typedescr=>describe_by_data( my_data ).

descr_ref1 ?= cl_abap_typedescr=>describe_by_data( my_data1 ).

*DATA: v_fieldname TYPE char30.

*DATA: v_char TYPE numc3.

DATA: it_fldcat TYPE lvc_t_fcat.

DATA: wa_it_fldcat type LVC_S_FCAT.

DATA: gp_table TYPE REF TO data.

DATA: v_char TYPE numc3.

DATA : DREF TYPE REF TO DATA.

data:dyn_wa type char2000 .

DO 65 TIMES.

v_char = sy-index.

if sy-index le 62.

read table descr_ref->components ASSIGNING <comp_wa> index v_char.

CLEAR wa_it_fldcat.

wa_it_fldcat-fieldname = <comp_wa>-name.

wa_it_fldcat-datatype = 'CHAR'.

wa_it_fldcat-outputlen = <comp_wa>-length.

wa_it_fldcat-intlen = <comp_wa>-length.

APPEND wa_it_fldcat TO it_fldcat .

else.

Do 34 times.

v_char = sy-index.

read table descr_ref1->components ASSIGNING comp_wa> index v_char.

CLEAR wa_it_fldcat.

wa_it_fldcat-fieldname = <comp_wa>-name.

wa_it_fldcat-datatype = 'CHAR'.

wa_it_fldcat-outputlen = <comp_wa>-length.

wa_it_fldcat-intlen = <comp_wa>-length.

APPEND wa_it_fldcat TO it_fldcat .

enddo.

endif.

ENDDO.

*Internal table creation..

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING it_fieldcatalog = it_fldcat

IMPORTING ep_table = gp_table.

ASSIGN gp_table->* TO <tb_file_data>.

ENDFORM. " get_dynamic_table

Could you please help on this.

I have tried to pass it_fldcat-inttype, but still getting the same dump.
