cl_alv_table_create=>create_dynamic_table to use for duplicate fields

[Former Member]

hi all,

i used cl_alv_table_create=>create_dynamic_table for creating dynamic internal table. the fieldcatalog contains a field (ATWRT) multiple times. it is showing a dump. may i know how to dynamically declare an internal table with fieldcatalog contains a field with multiple occurence?

Thanks in advance

yes. actually i need an internal table with N number of columns which can be determined at run time. it needs 10 to 100 columns of ATWRT field depends on selection logic. when i use cl_alv_table_create=>create_dynamic_table it is showing a dump. the code is,

• Get the structure of the table AUSP.

ref_table_des ?=

cl_abap_typedescr=>describe_by_name( lv_ausp ).

idetails[] = ref_table_des->components[].

loop at idetails into xdetails.

if xdetails-name eq 'ATWRT'.

gs_alv1_fc-fieldname = xdetails-name .

gs_alv1_fc-datatype = xdetails-type_kind.

gs_alv1_fc-inttype = xdetails-type_kind.

gs_alv1_fc-intlen = xdetails-length.

gs_alv1_fc-decimals = xdetails-decimals.

endif.

endloop.

loop at gt_ausp reference into lt_ausp.

append gs_alv1_fc to gt_alv1_fc.

endloop.

• Create dynamic internal table and assign to FS

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_alv1_fc

IMPORTING

ep_table = gt_alv1_data.

ASSIGN gt_alv1_data->* TO <gt_alv1_data>.

• Create dynamic work area and assign to FS

CREATE DATA gt_alv1_line LIKE LINE OF <gt_alv1_data>.

ASSIGN gt_alv1_line->* TO <gt_alv_wa>.

How do you remove the dynamic table/clean up when you dont need the table anymore. F.ex. If I need to make a dymaic table in my program several times ?.
