Hi,

Create the fieldcatalog using FM 'lvc_fieldcatalog_merge.'

and pass it to CALL METHOD cl_alv_table_create=>create_dynamic_table

Dynamic internal table is internal table that we create on the fly with flexible column numbers.

For sample code, please look at this code tutorial. Hopefully it can help you

Check this link:

http://www.saptechnical.com/Tutorials/ABAP/DynamicInternaltable/DynamicInternalTable.htm

For this purpose,

in my program,

there is an INDEPENDENT FORM

whose inputs are

TABLE NAME / STRUCTURE NAME

and from those, it consructs dynamic table.

2. Here is the program.

the dynamic table name will be

<DYNTABLE>.

3. U can use this program (FORM in this program)

to generate any kind of internal table

by specifying TABLE NAME .

REPORT abc.

*----

COMPULSORY

FIELD-SYMBOLS: <dyntable> TYPE ANY TABLE.

FIELD-SYMBOLS: <dynline> TYPE ANY.

DATA: lt TYPE lvc_t_fcat.

DATA: ls TYPE lvc_s_fcat.

FIELD-SYMBOLS: <fld> TYPE ANY.

DATA : fldname(50) TYPE c.

*----

parameters : iname LIKE dd02l-tabname.

*----

START-OF-SELECTION.

*----

PERFORM

PERFORM mydyntable USING lt.

BREAK-POINT.

*----

INDEPENDENT FORM

*----

FORM mydyntable USING ptabname.

*----

Create Dyn Table From FC

FIELD-SYMBOLS: <fs_data> TYPE REF TO data.

FIELD-SYMBOLS: <fs_1>.

FIELD-SYMBOLS: <fs_2> TYPE ANY TABLE.

DATA: lt_data TYPE REF TO data.

data : lt TYPE lvc_t_fcat .

DATA : ddfields LIKE ddfield OCCURS 0 WITH HEADER LINE.

*----

CALL FUNCTION 'DD_NAMETAB_TO_DDFIELDS'

EXPORTING

tabname = iname

TABLES

ddfields = ddfields.

*----

CONSTRUCT FIELD LIST

LOOP AT ddfields.

ls-fieldname = ddfields-fieldname.

APPEND ls TO lt.

ENDLOOP.

ASSIGN lt_data TO <fs_data>.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = lt

IMPORTING

ep_table = <fs_data>

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

IF sy-subrc <> 0.

ENDIF.

*----

Assign Dyn Table To Field Sumbol

ASSIGN <fs_data>->* TO <fs_1>.

ASSIGN <fs_1> TO <fs_2>.

ASSIGN <fs_1> TO <dyntable>.

ENDFORM. "MYDYNTABLE
