Transfering Data from one object to the other

[Former Member]

Hallo all,

i have to move detaildata from one instance to an other instance.

Both are instances of IF_REBD_MEAS_MNGR but they have different partents.

i tried with an simple go_object_trg = go_object_src but that doesn't work because the parent of go_object_trg changes to the original one and so the Data can't be stored because the target object diddn't change.

Can anyone help?

Thanks a lot

Hello,

If they have the same parent/interface you can use the following:

TRY.
    go_object_trg ?= go_object_src.
  CATCH CX_SY_MOVE_CAST_ERROR.
    WRITE: 'Error during cast'.
ENDTRY.

Hallo,

no they don't have the same parent.

is it possible to cast the objects and replace the parent after that cast?

I think this could help.

Best regards

First, obj1 = obj2 assigns the REFERENCES to the objects. Not the attributes. Essentially you end up with two references to the obj2. As you've found.

If I understand you correctly, you have two instances of different classes, say CL_A and CL_B, that implement the same interface, say IF_I?

Do something like:

DATA: obj1 TYPE REF TO cl_a,
      obj2 TYPE REF TO cl_b.

...some code that builds obj1 and obj2.

obj1->if_i~attrib1 = obj2->if_i~attrib1.
obj1->if_i~attrib2 = obj2->if_i~attrib2.

Or you could write a method something like:

obj1->get_attributes_of( obj2 ).

where get_attributes_of is implemented like:

me->if_i~attrib1 = i_obj->if_i~attrib1.
me->if_i~attrib2 = i_obj->if_i~attrib2.

Hi,

thanks for the Info.

It looks like this:

DATA:.....
 go_rental_object_vw TYPE REF TO if_rebd_rental_object,
          go_rental_object_mdt TYPE REF TO if_rebd_rental_object,
          go_meas_mngr_vw        TYPE REF TO   if_rebd_meas_mngr,
          go_meas_mngr_mdt        TYPE REF TO   if_rebd_meas_mngr.

And my problem ist, that the go_rental_object_vw with its attributes from go_meas_mngr_vw has to be overwritten with the attributes of go_meas_mngr_mdt

Did you understand me now?

Thanks a lot

Stefan

You have to do it attribute by attribute. There's no other way.
