RTTS dynamic DB table reference, how?

Hello all,

Here is a very simple program that will capture and write a list of the fields and their definitions of a database table that I have explicitly assigned to a variable using the type statement. I have been playing with this code and attempting to dynamically associate a database table structure with a variable, and then using that variable to assign it's structure to a <FS>. Everything that I tried generated a syntax error.

Could somebody please tell me what syntax I need to dynamically associate a database structure with a variable, versus statically?

This is the code.

data: dr_dref type ref to data,

rf_descr_ref type ref to cl_abap_typedescr .

data: <b>wa_vbap type vbak</b>. " DB table reference

field-symbols: <fs> type any.



  • Assign every field of this structure to the untyped field symbol.

assign component sy-index of structure <b>WA_vbap</b> to <fs>.

if sy-subrc ne 0.



call method cl_abap_typedescr=>describe_by_data


p_data = <fs>


p_descr_ref = rf_descr_ref.

write: / sy-index, rf_descr_ref->type_kind,

    here is the code sample. I guess this is what you wanted. right?

    type-pools : abap.
    data: wa_vbak type vbak .
    data : it_details type abap_compdescr_tab,
    wa_comp type abap_compdescr.
    data : ref_descr type ref to cl_abap_structdescr.
    ref_descr ?= cl_abap_typedescr=>describe_by_data( wa_vbak ).
    it_details[] = ref_descr->components[].
    break-point .
