for ex.passing structure name in parameter field of selection screen.

than loop through all it's component.

Thanks in advance

Here is some sample code:

FIELD-SYMBOLS: <fld> TYPE ANY.

DO.

ASSIGN COMPONENT sy-index OF STRUCTURE p_struc TO <fld>.

IF sy-subrc NE 0.

EXIT.

ENDIF.

do something with your component

ENDDO.

Hi,

Check this


PARAMETERS: str(40) type c.

DATA: lr_rtti_struc TYPE REF TO cl_abap_structdescr.
DATA: lt_comp       TYPE cl_abap_structdescr=>component_table.
DATA: ls_comp       LIKE LINE OF lt_comp.
 
    lr_rtti_struc ?= cl_abap_structdescr=>describe_by_name( STR ).
    lt_comp = lr_rtti_struc->get_components( ).
 
 "lt_comp as all the components of the structure.
loop at lt_comp into ls_comp.
write: ls_comp-name.
endloop.
 " execute this code by passing any structure
