CAST with deep structure

Former Member — Sun, 12 May 2013 20:42:38 GMT

I'm trying to do a generic code but I'm having trouble with deep structure,

I have different class with different deep structure exporting parameters,

It is possible to do a "CASTING" with deep structure? Or have another way to solve my problem?

Here is the problem:

FIELD-SYMBOLS: <fs_output> TYPE ANY.
DATA: obj_class TYPE REF TO object.

CREATE OBJECT obj_class TYPE (str_proxy).

<fs_output> = wl_output1-mt_confirma_proc_palete_transf-num_id .

      CALL METHOD obj_class->(str_method)
        EXPORTING
          output = <fs_output>. "--> CX_SY_DYN_CALL_ILLEGAL_TYPE

Hi,

I think the parameters passing can't be generic in nature in OO ABAP.

Hi Bruno,

I think you have different parameters in the method that you calling and the type of field symbol. Make sure that the type of output is ANY.

Yes, I have differente parameters, I need do a CAST for deep structure, something like that:

<fs_output> = wl_output1-mt_confirma_proc_palete_transf-num_id CASTING TYPE (str_ty_deep_structure).

But this code return a Illegal casting...

Hi Bruno,

When dynamically calling methods you must use parameter table instead of exporting/importing. Refer to online help for call method (<f1>) and this doco: http://help.sap.com/abapdocu_70/en/ABAPCALL_METHOD_SHORTREF.htm

Hi Bruno,

I have given a link on field symbol casting refer to that, you may get some ideas of casting and where you going wrong.
