The second version of the OData protocol allows you to add annotations to the metadata document; the purpose of the annotations is to add information and hints to the EDM elements. OData MPC_EXT-DEFINE Code Collection; Mary Roopini A on SEGW – OData MPC_EXT-DEFINE Code Collection; Soko on How. We could implement a code block like so in the DEFINE method of the MPC_EXT class and add the desired term directly as an attribute of the produced oData property: The backend code would look something like: DATA(lo_entity_type) = model->get_entity_type( 'YourEntityType' ). Hello SAP Community, In the MPC_EXT of OData project we can add Data Dictionary Search Help using the class cl_fis_shlp_annotation=>create by specifying the SE11 search help as input parameter.

SEGW does not yet allow you to add most of the annotations. Class CL_GUI_TIMER raises event FINISHED after the timer has completed its INTERVAL in seconds. The CDS view created was used as a Data Source and transaction behavior were managed through Gateway methods overriding the MPC_EXT and making specific entity as sap:creatable. A CDS custom entity provides the signature of. Resolution. DPC& DPC_EXT; MPC & MPC_EXT; The mentioned above are four classes generated by SAP. 1] Re-define MPC. For OData version 2. Now click ‘Save’ and ‘Generate Runtime Objects’. datetime alone is not enough to ensure proper conversion during OData parsing.

We can then fetch data using get_entityset method of DPC_EXT class. . Step 2. I have set up the update stream (DPC_EXT class) and the MPC_EXT (Define method). The generated definition for the OData service is contained in this class: ZCL_ZODATA_SERVICE_MPC, however, to implement the desired logic, the ZCL_ZODATA_SERVICE_MPC_EXT class will be extended with the additional code. Here you can override the define( ) method in the MPC_EXT class as described here for another used case. If we implement any code in DPC/MPC while generating runtime object the code gets deleted. Odata service . 16 28 48,979.

Pankaj on SAPScript symbols and formatting options. lo_entity_type. We consume this RFC in oData Service in such a manner, so that in a single call via one EntitySet, oData Service should return multiple EntitySet output (which is mapped from multiple table output of RFC). To enable batch processing, in DPC_EXT class redefine method /iwbep/if_mgw_appl_srv_runtime~changeset_begin. Call the super->define method, which will create all the properties and the annotations already maintained. Collection of code snippets which I regularly use in MPC_EXT DEFINE method.
