How to get data from table reference into ITAB?

[martin_lehmann4]

Hello all,

I try to use methods cl_rssh_hierarchy_func=>get and cl_rssh_hierarchy_func=>update - in doing so both methods are working fine, i.e. the first delivers a subtree in parameter E_R_HTAB with Type Ref To DATA and the update method writes a subtree back to the hierarchy with parameter I_T_HTAB and Type TABLE. Unfortunately I have an issue transforming the hierarchy data from Ref To DATA into an ITAB for the TABLE parameter - one of my attempts amongst others was this one:

           DATA: lt_htab            TYPE rshi_t_rsnode1,
                    ls_htab            LIKE LINE OF lt_htab,
                    lr_htab            TYPE REF TO data,
                    dref               TYPE REF TO data,
                    lt_htab_dref   LIKE TABLE OF dref.

           FIELD-SYMBOLS: <ls_rsthiernode>  LIKE LINE OF mt_rsthiernode,
                                       <dpak_fields> TYPE any,
                                        <s_hieid>        TYPE rshieid.
             

    CREATE DATA lr_htab LIKE LINE OF lt_htab

           *

           * getting subtree with cl_rssh_hierarchy_func=>get here
           *

             GET REFERENCE OF lt_htab_dref INTO lr_htab.
             ASSIGN lr_htab->* TO <dpak_itab>.

            LOOP AT lt_htab_dref ASSIGNING <dpak_fields>.
               ASSIGN COMPONENT 'RSHIEID' OF STRUCTURE <dpak_fields> TO <s_hieid>.
               ls_htab-hieid = <s_hieid>.
               APPEND ls_htab TO lt_htab.
            ENDLOOP.

           *

           * writing subtree with cl_rssh_hierarchy_func=>update here
           *

Sadly no data is in structure c_t_srcpak ...

Can you show me an example which solves this task?

Best regards, Martin

Hello once more,

the problem is solved, it works like this:

  DATA:     lt_htab            TYPE rshi_t_rsnode1,
                 ls_htab            LIKE LINE OF lt_htab,
                 lr_htab            TYPE REF TO data.
  FIELD-SYMBOLS:

                 <dpak_itab>        TYPE ANY TABLE,
                 <dpak_fields>      TYPE LINE OF rshi_t_rsnode1,
                 <s_hieid>          TYPE rshieid.

  CREATE DATA lr_htab LIKE LINE OF lt_htab.

           *

           * getting subtree with cl_rssh_hierarchy_func=>get here
           *

  ASSIGN lr_htab->* TO <dpak_itab>.

  LOOP AT <dpak_itab> ASSIGNING <dpak_fields> CASTING.
    ASSIGN COMPONENT 'HIEID' OF STRUCTURE <dpak_fields> TO <s_hieid>.
    ls_htab-hieid = <s_hieid>.

    "further processing ...
    APPEND ls_htab TO lt_htab.
  ENDLOOP.

Hi Martin,

                 Hi Saw your post that with GETREFERENCE  and with out GETREFERENCE and you used CASTING when Looping, can you explain why you kept CASTING in Looping and i also tried but it is giving error and i declared <dpak_fields> type any , So i changed like line of lt_htab and i am not getting error .

So , Please explain the Purpose of CASTING .

Thanks,
