How to access MPC from DPC?

[Former Member]

hello.

i want to access the MPC from the DPC methods, i.e. ..._GET_ENTITYSET(). How to retrieve the instance of te MPC connected to the current DPC?

background info:

i want to use the labels assigned to ABAP structure components of an entity type without hard.coding them...

cheers

here comes the solution:

* determine name of OData property assigned to ABAP field VBELN
   data:
     facade      type ref to /iwbep/cl_mgw_dp_facade,
     model       type ref to /iwbep/if_mgw_odata_re_model,
     entity_type type ref to /iwbep/if_mgw_odata_re_etype,
     properties  type /iwbep/if_mgw_odata_re_prop=>ty_t_mgw_odata_properties,
     name        type string.

   field-symbols:
     <property> type line of /iwbep/if_mgw_odata_re_prop=>ty_t_mgw_odata_properties.

   facade ?= me->/iwbep/if_mgw_conv_srv_runtime~get_dp_facade( ).
   model = facade->/iwbep/if_mgw_dp_int_facade~get_model( ).

   entity_type = model->get_entity_type( |{ iv_entity_name }| ).
   properties = entity_type->get_properties( ).

   read table properties
     assigning <property>
     with table key technical_name = 'VBELN'.

   if sy-subrc eq 0.
     name = <property>-property->get_name( ).
   endif.

has anybody ever tried to retrieve the model instance /iwbep/if_mgw_odata_re_model while instantiation of the DPV? in my case it seems to create a dump....

i would like to retrieve the model in CONSTRUCTOR and store its reference in an instance attribute, so that all other methods can access it easily...

Mike,

What you require is model instance, not the MPC instance itself.

Here it is.
