Populating dynamically added components

Shky — Tue, 29 Apr 2008 08:16:27 GMT

Hi,

I have a structure Struc1 (Components A,B,C,D).

During my runtime, I add components to this structure and now it has (A,B,C,D, X1,X2) as follows.

DATA:

lr_struc TYPE REF TO cl_abap_structdescr,

lt_comp TYPE cl_abap_structdescr=>component_table.

ls_comp-name = 'X1'.

ls_comp-type ?= cl_abap_structdescr=>describe_by_name( 'OBJID' ).

APPEND ls_comp TO lt_comp.

ls_comp-name = 'X2'.

ls_comp-type ?= cl_abap_structdescr=>describe_by_name( 'OBJID' ).

APPEND ls_comp TO lt_comp.

Now I have the following to populate the data.

DATA: ls_struc1 type Struc1. "Defined above

Field-symbols: <Ls_data> type any.

MOVE CORRESPONDING ls_struc1 TO <ls_data>.

now the fields A,B,C,D are populated for <ls_data>.

But how do I do the same for fields X1 and X2. I see them as fields for <ls_data> in the runtime, but not sure how to populate that.

(ie., how to get <ls_data>-X1 and <ls_data>-X2. )

Can someone help me?

Regards,

Shalini.

u can use like this

FIELD-SYMBOLS: <eval_wa> TYPE pay_eval_period.

DATA: l_eval_tab TYPE pay_t_eval_period.

LOOP AT l_eval_tab ASSIGNING <eval_wa>.

Hi,

Thanks for the reply.

I need to populate a structure of type ANY ie., <ls_data>.

Thanks,

Shalini.

Hi,

Try to use the following syntax:

Field-symbols: <fs> type any.

DO.

Assign component sy-index of structure <ls_data> to <fs>.

if sy-subrc = 0.

<fs> = 'value to be populated'.

else.

exit.

endif.

ENDDO.
