CX_SY_MOVE_CAST_ERROR - Source type CLASS=CL_SRQM_INC_INCIDENTSRL_CN00 is

[Former Member]

Hi,

I added a Z field with AET. After adding AET field I generated Getter and Setter methods. After adding Getter and setter methods WEB UI started to give below error;

"CX_SY_MOVE_CAST_ERROR - Source type CLASS=CL_SRQM_INC_INCIDENTSRL_CN00 is not compatible, for the purposes of assignment, with target type CLASS=ZL_SRQM_INC_INCIDENTSRL_CN00 "

I know after generating Getter and Setter for Z fields, CL_SRQM_INC_INCIDENTSRL_CN00 now differs from ZL_SRQM_INC_INCIDENTSRL_CN00. I have copied super class of ZL_SRQM_INC_INCIDENTSRL_CN00, I changed class names from CL.. to ZL but it did not work.

How can i fix it up? Could someone help me? I need to use Getter and Setter methods of Z fields. What is your advice?

Best wishes,

Solution is

go to class ZL_SRQM_INC_INCIDENTSRL_IMPL

then go method WD_CREATE_CONTEXT

correct the code as the following;

method WD_CREATE_CONTEXT.

• create the context

super->wd_create_context( ).

context = cl_bsp_wd_context=>get_instance(

iv_controller = me

iv_type = 'ZL_SRQM_INC_INCIDENTSRL_CTXT' ).

typed_context ?= context.

ztyped_context ?= context.

• super->wd_create_context( ).

• Added by wizard

endmethod.

Hi Umit,

What is the super class of ZL_SRQM_INC_INCIDENTSRL_CN00?

Give the class CL_SRQM_INC_INCIDENTSRL_CN00 as superclass.

I wrote the issue to SAP OSS. They sent me a solution, it was helpful but incomplete. I completed the solution. Solution is as the following;

Go to class ZL_SRQM_INC_INCIDENTSRL_IMPL's method WD_CREATE_CONTEXT;

Code of method should be like this;

method WD_CREATE_CONTEXT.
*   create the context
  super->wd_create_context( ).

  context = cl_bsp_wd_context=>get_instance(
          iv_controller = me
          iv_type = 'ZL_SRQM_INC_INCIDENTSRL_CTXT' ).

  typed_context ?= context.
  ztyped_context ?= context.

endmethod.

First thing u dont hv to copy super class. when u enhance it SAP automatically manage it everything. Just simply create Setter Getter method. It sud work.

Where exactly do you have an error? I mean exact peace of code.

It seems that you try to call some method which return standard class.

Hi Joshi,

I applied that before. It resolves only the problem of generating getter and setter for fields created EEWB and AET. My problem is different from this.

Hi Andrei,

I tell you what i did exactly;

Firstly, I created a Z field with AET. The name of field is ZZAFLD000008.

Secondly, I extended SRQM_INCIDENT_S's IncidentSRL view.

After second step there is no problem I can use view wthout any problem.

Thirdly, I generated getter and setter of ZZAFLD000008.

After third step I get error

"CX_SY_MOVE_CAST_ERROR - Source type CLASS=CL_SRQM_INC_INCIDENTSRL_CN00 is not compatible, for the purposes of assignment, with target type CLASS=ZL_SRQM_INC_INCIDENTSRL_CN00 "

Then my intention is adding a Z field and change its value when listing service request.

Thanks

Ümit Yılmaz,

when the error is generated it's also shown the place (class and method) and the code line of the error (line number). I've asked what exactly in the line which is generated the error.

endmethod.

The above method is standard method, I think I did something wrong or incomplete.

First of all put a break-point in this method (CL_BSP_PAGE_BASE=>IF_BSP_PAGE~SET_ATTRIBUTE). And check the call stack. You'll see from where it is called.

Seems that for some reason you (or generated code in Z-class) call a SET-method.

I've actually checked the component and it seems that this is search result view. If so you do not need to have SET-method at all because it's only a list and get-methods only are required.
