Since there are currently no plans to downport the feature to 750 Sérgio Fraga plans to post his implementation as a blog post. After this i deleted DPC_EXT and MPC_EXT classes. we will not write any logic inside MPC and DPC classes. . Create a Gateway project: ZMEDIALNK_SB. With the use of annotations and Smart components like SmartTable you can minimize the UI View code to be written for conventional scenarios like listing and filtering data. commons. Right click on ZCL_ZTEST_MPC_EXT and select on Workbench option. But. you can use the method Define to create entity, properties etc using code based implementation. This documentation explains how an OData service can be created and deployed in an SAP system. Within the DEFINE method I set the entity type as aggregation. How to you treat in UI5 the return of insert data table?SAP changed from an internal to ISO standard currency code in the OData APIs to be compliant with ISO standards which led to the change of the property length from 5 to 3 in OData V4 services. in sap-ds-debug flag) and parameter aliases (defines aliases for use in entity keys).

Step 9: Now right click on data definition projection to create a new Service Definition. Create a table where we will have the package name stored. Step 4: Enhance Logic in Metadata using Class MPC_EXT and DEFINE Method. Model Provider Extension Class (suffix _MPC_EXT): This is the implementation class that inheritsWe are making use of importing parameter iv_slug to get some of the information. g. We can create dynamic entity using Define () method of MPC_EXT class. Entity Type 4 – ord_opr. Add following lines of code in method DEFINE of the MPC_EXT class. Step 2. To activate the SAP Gateway, go to Customizing for SAP NetWeaver under SAP Gateway OData Channel Configuration Activate or Deactivate SAP Gateway . New techniques. Go to Runtime Artifacts node, open the ZCL_ZGW_PRACTICE006_ MPC_EXT class in ABAP Workbench ( Right-Click: Go to ABAP Workbench) & click on the Types tab. After analyzing source code, unit tests and some intensive debugging sessions I managed to bind TreeTable to Odata. The below pop-up window will appear. Log onto the SAP NetWeaver Gateway system.

So we have to use the option to add additional metadata by implementing the DEFINE method in the model provider extension class. If we implement any code in DPC/MPC while generating runtime object the code gets deleted. This document provides details for generating MPC for two Project Types: This is the Implementation class that inherits Base class. The URL should include the entityset-name and filter-options when necessary like in the screenshoot above. SAP OData is relevant only if the SAP systems acts as a service or data provider. The Open Data Protocol (OData) includes standard CRUD (Create, Retrieve, Update, and Delete) operations that map to the HTTP methods POST, GET, PUT/MERGE, and DELETE. Entity Type 3 – ord_comp. Annotate the entity by redefining the DEFINE() method within the generated *_MPC_EXT Class. 11. Activate it. See rules 5, 6 & 7. You want to modify the service with custom code implementations. Direction: drag from tree and drop in ALV control. But it doesn't add an annotation to the metadata. Here is an example of the implementation for this class. T Fdo. Remember that at this stage your fully functioning OData service is a result of purely declarative definitions. Click Add assignment – Give the service name generated (in point 1) and click “Enter”. Business cases: 1. Example,*AE*,*AG41-1S*. The Wizard Step 1 of 2:. Entity Type 2 – ord_hdr. Underneath we find the “Data Model” node. BCALV_DND_01 – Drag ALV Row to Tree Folder. ), custom query options (extensibility mechanism, used eg. Create Deep Entity. A service can be called an API that SAP provides to their consumers. create a new complex type there. So we can define model as a ABAP class ZODATA_MODEL_CLASS inherited from super class IWBEP/CL_MGW_ABS_MODEL. ENDMETHOD. Value Help F4. You redefining existing (SAP standard) SEGW project where code based annotations are used. 2. My CDS views are shown below at the code section. Save it. Now, For example, If You have defined 3 Properties in your entity type. Select the entity type “ZFILE” you just created and Choose the check box media as selected. The Reference Data Source Wizard opens. String with a length 1000). In the sub nodes of the “Data Model” node the data definition and the relations between them will be defined. CDS View: Annotation. Below is the architecture of ABAP RESTful Application Programming Model to develop Odata services. dpc_ext class. SAP Gateway Deep Insert End to End Scenario. They also advertise capabilities that go beyond the base set defined by OData, e. Now go to menu Extras->Other Requests->Add. Create an entity ‘TEST’ with one dummy attribute (VBELN).

Generating the Runtime Artifacts redefines and implements the following operations in the data model provider base class: Create, Read, Update, Delete (CRUD), and Query. When using the generic framework support the following happens when using eTags. Step 1. But there are situations where you need to do this for example implementing form user exits in SD, creating objects as per sap notes etc. Figure 1.

Entity Type 6 – return (created to hold multiple messages of type BAPIRET2) Then I also annotated my Entity and properties with "aggregate" and dimension/measure through MPC_EXT(redefining DEFINE method). t. We will know how to pass this information from UI when we code for UI5. The Base Class CL__<Project Name>_MPC generated will have DEFINE() method. To enable transaction capabilities on the item set, I updated the CDS entity as sap:creatable="true" and sap:updatable="true" by overriding the MPC_EXT "DEFINE" method. 16 28 49,455.
