How to use global classes and display returned data?

Question

Hello experts,
I have the following code in a program which accesses a global class (found in the class library). It executes one it's static methods. What I would like to do is to get hold of some elements of the returned data. How do I do that please?
Your help is greatly appreciated.
***Use global class CL_ISU_CUSTOMER_CONTACT
DATA: o_ref TYPE REF TO CL_ISU_CUSTOMER_CONTACT.
DATA: dref_tab LIKE TABLE OF O_ref.
DATA: begin OF o_ref2,
CONTACTID               TYPE CT_CONTACT,
P_INSTANCES             TYPE string,
P_CONTEXT               TYPE CT_BPCCONF,
P_CONTROL               TYPE ISU_OBJECT_CONTROL_DATA,
P_DATA                  TYPE BCONTD,         "<<<=== THIS IS A STRUCTURE CONTAINING OTHER DATA ELEMENTS
P_NOTICE                TYPE EENOT_NOTICE_AUTO,
P_OBJECTS               TYPE BAPIBCONTACT_OBJECT_TAB,
P_OBJECTS_WITH_ROLES    TYPE BAPIBCONTACT_OBJROLE_TAB,
end of o_ref2.
TRY.
    CALL METHOD CL_ISU_CUSTOMER_CONTACT=>SELECT  "<<<=== STATIC METHODE & PUBLIC VISIBILITY
      EXPORTING
       X_CONTACTID = '000001114875'   "Whatever value here
      RECEIVING
        Y_CONTACTLOG = o_ref
ENDTRY.
WHAT I WOULD LIKE TO DO IS TO MOVE o_ref TO o_ref2 and then display:
1) P_DATA-PARTNER
2) P_DATA-ALTPARTNER
How can I do this please?

I now have the following code. But when I check for syntax I get different error. They are at the end of the list.
Here is the code the way it stands now:
================================================
***Use global class CL_ISU_CUSTOMER_CONTACT
DATA: oref TYPE REF TO CL_ISU_CUSTOMER_CONTACT.
DATA: dref_tab LIKE TABLE OF oref.
DATA: begin OF oref2,
CONTACTID TYPE CT_CONTACT,
P_INSTANCES TYPE string,
P_CONTEXT TYPE CT_BPCCONF,
P_CONTROL TYPE ISU_OBJECT_CONTROL_DATA,
P_DATA TYPE BCONTD,      "THIS IS A STRUCTURE CONTAINING OTHER DATA ELEMENTS
P_NOTICE TYPE EENOT_NOTICE_AUTO,
P_OBJECTS TYPE BAPIBCONTACT_OBJECT_TAB,
P_OBJECTS_WITH_ROLES TYPE BAPIBCONTACT_OBJROLE_TAB,
end of oref2.
TRY.
CALL METHOD CL_ISU_CUSTOMER_CONTACT=>SELECT     " STATIC METHODE & PUBLIC VISIBILITY
EXPORTING
X_CONTACTID = '000001114875' "Whatever value here
RECEIVING
Y_CONTACTLOG = oref
ENDTRY.
field-symbols: <FS1>      type any table,
               <wa_oref2> type any.
create data dref_tab type handle oref.   " <<===ERROR LINE
assign dref->* to <FS1>.
Loop at <FS1> assigning  <wa_oref2>.
*use <wa_orfe2> to transfer into oref2.
endloop.
write: / 'hello'.
=========================================
Here are the errors I get:
The field "DREF" is unknown, but there is a field with the similar name "OREF" . . . .
When I replace itr by OREF I get:
"OREF" is not a data reference variable.
I then try to change it to dref_tab. I get:
"DREF_TAB" is not a data reference variable.
Any idea? By the way, must there be a HANDLE event for this to work?
Thanks for your help.
