Enhance oData service

[Former Member]

Hello. I extended oData service /IWPGW/TASKPROCESSING v.2 and added new property "Ext" to entity Task. Service generated whithout errors. But when I try to run the service in gateway client, then I get error "Property 'Ext' of data object 'Task' has no Internal type assigned". In my model class this field is exist and has data type "string". What did I do wrong? If I delete new property, then service run correctly

Hi Pavel,

May be you can try to assign internal type to the new property using the following code in DEFINE method if MPC_EXT.

data: lr_tntity_type type REF TO /iwbep/if_mgw_odata_entity_typ,
      .r_property TYPE REF TO /iwbep/if_mgw_odata_property.


  super->define( ).


  lr_tntity_type = model->get_entity_type( 'ENTITYNAME' ).


  lr_property = lr_tntity_type->get_property( 'PROPERTYNAME' ).
  lr_property->SET_INTERNAL_TYPE( cl_abap_typedescr=>TYPEKIND_STRING ).

Thanks all! I Redefined DEFINE method and added internal property type like Atanu in his replay. Issue solved

Hi Atanu,

On redefining gateway service, the date field type in child service changed to Packed (21,7) /Packed (15,0).

I want to change the date type from Packed (21,7) /Packed (15,0) to Internal Type Date(D).

Please suggest a way to change the same.

Regards,

Priyanka.

Hello Pavel,

This may be because you have added a new property to the GW Model but missed adding the same to the structure which is bound.

At the runtime internally there would be a check which maps properties to the structure which is bound to it.

In the MPC class you will see a structure which is bound as below.

lo_entity_type->bind_structure( '<Your Structure Name>' ).

You need to add the field in this structure as well.

Check this structure and add that particular field.

Ashwin

I remember having this error earlier and did not find anything wrong. I somehow did not need that enhancement later.

I would suggest raising it to SAP.
