[Former Member]

Hi friends,

can anyone tells me how to access Structure component dynamicaly?

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
