Hi check the following sample code.

type-pools: slis.

field-symbols: <dyn_table> type standard table,

<dyn_wa>.

data: alv_fldcat type slis_t_fieldcat_alv,

it_fldcat type lvc_t_fcat.

selection-screen begin of block b1 with frame title text-001.

parameters: p_flds(5) type c.

selection-screen end of block b1.

start-of-selection.

*build the dynamic internal table

perform build_dyn_itab.

*write 5 records to the alv grid

do 5 times.

perform build_report.

enddo.

*call the alv grid.

perform call_alv.

************************************************************************

*Build_dyn_itab

************************************************************************

form build_dyn_itab.

data: new_table type ref to data,

new_line type ref to data,

wa_it_fldcat type lvc_s_fcat.

*Create fields .

clear wa_it_fldcat.

wa_it_fldcat-fieldname = 'name1'.

wa_it_fldcat-datatype = 'mara-matnr'.

wa_it_fldcat-intlen = 5.

append wa_it_fldcat to it_fldcat .

*

*clear wa_it_fldcat.

wa_it_fldcat-fieldname = sy-index.

wa_it_fldcat-datatype = 'CHAR'.

wa_it_fldcat-intlen = 5.

append wa_it_fldcat to it_fldcat .

*

do p_flds times.

clear wa_it_fldcat.

wa_it_fldcat-fieldname = sy-index.

wa_it_fldcat-datatype = 'CHAR'.

wa_it_fldcat-intlen = 6.

append wa_it_fldcat to it_fldcat .

enddo.

*Create dynamic internal table and assign to FS

call method cl_alv_table_create=>create_dynamic_table

exporting

it_fieldcatalog = it_fldcat

importing

ep_table = new_table.

assign new_table->* to <dyn_table>.

*Create dynamic work area and assign to FS

create data new_line like line of <dyn_table>.

assign new_line->* to <dyn_wa>.

endform.

*********************************************************************

*Form build_report

*********************************************************************

form build_report.

data: fieldname(20) type c.

data: fieldvalue(5) type c.

data: index(3) type c.

field-symbols: <fs1>.

do p_flds times.

index = sy-index.

*Set up fieldvalue

concatenate 'FLD' index into

fieldvalue.

condense fieldvalue no-gaps.

assign component index of structure <dyn_wa> to <fs1>.

<fs1> = fieldvalue.

enddo.

*Append to the dynamic internal table

append <dyn_wa> to <dyn_table>.

endform.

************************************************************************

*CALL_ALV

************************************************************************

form call_alv.

data: wa_cat like line of alv_fldcat.

do p_flds times.

clear wa_cat.

wa_cat-fieldname = sy-index.

wa_cat-seltext_s = sy-index.

wa_cat-outputlen = '6'.

append wa_cat to alv_fldcat.

enddo.

*Call ABAP List Viewer (ALV)

call function 'REUSE_ALV_GRID_DISPLAY'

exporting

it_fieldcat = alv_fldcat

tables

t_outtab = <dyn_table>.

endform.
