Thanks for your quick reply,
I used your logic like this.
data:
ls_component type abap_componentdescr,
lt_component type abap_component_tab.
*... (1) define structure components :
clear ls_component.
ls_component-name = 'NVALUE'.
ls_component-type ?= cl_abap_typedescr=>describe_by_name( <fs_seg_v>-fieldname ).
insert ls_component into table lt_component.
*... (2) create structure
data lr_strucdescr type ref to cl_abap_structdescr.
data lr_data_struc type ref to data.
lr_strucdescr = cl_abap_structdescr=>create( lt_component ).
create data lr_data_struc type handle lr_strucdescr.
field-symbols <fs> TYPE any.
assign lr_data_struc->* to <fs>.
your logic is working fine.
here I am getting feild name (<fs_seg_v>-fieldname) from internal table.
But I need to assign same field name structure to query parameter.
FIELD-SYMBOLS: <ls_query_params> TYPE lty_stru_input.
Please can you suggest how I can refer the field name structure?
