read field value from table inside nested structure.

Hi Team

i need to read value of field (Check) from the below deep structure ,

HRDATA.STAR_CHEQUE-CHEQUE_FPAYHX-CHECK..

here HRDATA is structure of /1PYXXFO/ZHR_PAYSTUB.

STAR_CHEQUE is table type defined on /1PYXXFO/ZHR_PAYSTUB_____M0030.

CHEQUE_FPAYHX is defined on structure FPAYHX

CHECK is field of char13 field of FPAYHX.

i tried the below code ,

DATA table_descr TYPE REF TO cl_abap_tabledescr.
DATA struct_descr TYPE REF TO cl_abap_structdescr.
DATA columns TYPE abap_compdescr_tab.
FIELD-SYMBOLs
<column> LIKE LINE OF columns.
 table_descr
?= cl_abap_typedescr=>describe_by_data( HRDATA-STAR_CHEQUE ).
struct_descr ?= table_descr->get_table_line_type( ).
columns = struct_descr->components.

now i went a level where i see the fields of STAR_CHEQUE are moved to field symbol columns. now how do i read CHEQUE_FPAYHX structure then the filed CHECK?

Please help with this?

Thanks

Why do you use RTTI?

Hi Sandra ,

Thanks for the reply , the above code is reference from another post. now i tried the alternative way , but i see componet of <FS-STRCT2> is not assigning to <FS-STRCT2> . Please suggest

FIELD-SYMBOLS : <FS-STRUCT1> TYPE any,
                <FS-STRUCT2> TYPE ANY ,
                <fs_wa> type FPAYHX.
data: lv_comp_name(20) type c value 'CHEQUE_FPAYHX'.
ASSIGN HRDATA-STAR_CHEQUE[] to <FS-STRUCT1>.
ASSIGN COMPONENT lv_comp_name OF STRUCTURE <FS-STRUCT1>  TO <FS-STRUCT2>.

Same question for ASSIGN with dynamic naming, isn't your variable HRDATA typed statically? Do you mean that you don't have this line of code (or parameter)?

DATA hrdata TYPE /1PYXXFO/ZHR_PAYSTUB.

If so, you don't need ASSIGN, its components may be accessed directly.

PS: minus character in names is obsolete and forbidden in ABAP Objects.

If your ABAP release is >= 7.40, use:

LOOP AT hrdata-star_cheque ASSIGNING FIELD-SYMBOL(<line_of_star_cheque>).
  IF <line_of_star_cheque>-cheque_fpayhx IS INITIAL.
    ...
  ENDIF.
ENDLOOP.

PS: I advise using "good" names, bad practice in your code is to name <STRUCT1> a field symbol which refers to the internal table STAR_CHEQUE.
