Loading the metadata for service failed - Data object not found

[Former Member]

Hello SAP Gateway Expert,

I'm using the Gateway for some times now and I encountered a strange error.

I created a service with Entities based on ABAP RFM and it was working fine. I added an association to manage a DEEP_ENTITY creation and now I have an error when I try to use the service.

From /n/iwfnd/maint_service, when I select my service and click the button "Load metadata", I get an error "Loading the metadata for service 'Z_PDE_CREATE_SRV' failed. Check the error log. "

And the error log is telling "Data object 'HeaderPDESet' not found" which strange because the object is existing !

I deleted and recreated the Entity and the EntitySet, I regenerated the project, I cleaned the caches /IWFND/CACHE_CLEANUP and /IWBEP/CACHE_CLEANUP.

For no effect... Any clue is appreciated !

Thanks,

Luc

Hello Ashwin,

Sorry for the delay answering I was really not available...

Thanks this was the major part of the problem !

The second part is that I put the EntitySet name inseatd of the Entity Name !

How can I reward you ?

Hello Luc,

Model looks fine.

Have you written any code in MPC_EXT class inside Define method ?

Hello Ashwin,

Yes I did.

Here it is :

method DEFINE.

DATA:

lo_annotation TYPE REF TO /iwbep/if_mgw_odata_annotation,

lo_entity_type TYPE REF TO /iwbep/if_mgw_odata_entity_typ,

lo_complex_type TYPE REF TO /iwbep/if_mgw_odata_cmplx_type,

lo_property TYPE REF TO /iwbep/if_mgw_odata_property,

lo_entity_set TYPE REF TO /iwbep/if_mgw_odata_entity_set.

***************************************************************************************************************

* ENTITY - Deep Entity

***************************************************************************************************************

lo_entity_type = model->get_entity_type( iv_entity_name = 'HeaderPDESet' ).

lo_entity_type->bind_structure( iv_structure_name = 'ZCL_Z_PDE_CREATE_MPC_EXT=>TS_DEEP_ENTITY' ).

endmethod.

And I created also the TS_DEEP_ENTITY

class ZCL_Z_PDE_CREATE_MPC_EXT definition

public

inheriting from ZCL_Z_PDE_CREATE_MPC

create public .

public section.

types:

begin of TS_DEEP_ENTITY,

include type TS_HEADERPDE,

headeritem type STANDARD TABLE OF TS_ITEMLIST with DEFAULT KEY,

headerpartner type STANDARD TABLE OF TS_PARTNERLIST WITH DEFAULT KEY,

END OF TS_DEEP_ENTITY .

methods DEFINE

redefinition .

Inside DEFINE method first please call the super class as below and then your custom code.

method DEFINE.

DATA:lo_entity_type TYPE REF TO /iwbep/if_mgw_odata_entity_typ.

super->define( ).

***************************************************************************************************************

* ENTITY - Deep Entity

***************************************************************************************************************

lo_entity_type = model->get_entity_type( iv_entity_name = 'HeaderPDESet' ).

lo_entity_type->bind_structure( iv_structure_name = 'ZCL_Z_PDE_CREATE_MPC_EXT=>TS_DEEP_ENTITY' ).

endmethod.
