An attempt to show how we can reduce code lines using ABAP 7. In the next screen enter below inputs to create Soheaderdata entitytype and SoheaderdataSet entityset. Specify association name, principal entity type name, dependent entity type name, Cardinality and Navigation Property in below window. Specify referential constraints between Soheaderdata and Soitemdata and specify key relation in below window. Now create association and navigation property between Soitemdata and ProductHeaderdata similar way.
In the next steps, we will implement data provider class methods to retrieve data. In service implementation folder, for SoheaderdataSet entity set, we will implement method for GetEntitySet Query to retrieve all sales orders header data. Get Filter and orderby URI parameter values. Filter or selection URI parameters can retrieved using below method.
We can use below URL:. In the above code using sales order number and item number, getting corresponding product number. However, for the scenario stated above, it would never have a product and we should deduce the product from the information specified in the navigation path.

Here I will perform these operations on Z table. In real scenarios, you will use BAPIs.
RFCs to perform these operations. I recommend to read below documents and SAP documentation for deep understanding. Code Snippet — 3. Provide DDIC structure name. It will propose field and key mapping as well as object name which will be your entity name.
I want my field names in upper camel case format so I will change it accordingly. It will look as below. Press enter. I will go with UserCollection as my entity set name. Right click folder name Entity Sets and click create. It will display as below.
Click on generate runtime objects button. It will display popup as below. Keep the default class names as-is and click on enter button. On successful generation, you will see this kind of message log and generated artifacts.
Now register your service under service Maintenance folder. Click on Register button. Keep default values as-is and hit enter button. On successful registration, click Maintain button. This will open service catalog window along with option to call Gateway Client.
Click on Gateway Client button to test the service. Metadata provides information such as Entity type, key property, properties and Entity Set name. So far we just defined single entity type and entity set. First we will start implementing query operation. Observe the method signature. You will find important information in method parameters in debugging mode. Below table will provide brief explanation of method parameters, alternative approach to get the value of those method parameters.
Last column specifies if we need to code to implement query operation. Yes UserCollection? Below is the minimal code that we need to have in this method. Below is the code that will perform POST operation. In case you execute GET operation i.For this tutorial and the subsequent mobile tutorial please select the Neo Trial environment.

Nice Blog. There is one more way, where you can directly bind the CDS view to the entity. So we dont need to write the code to fetch the data. SADL layer will fetch the data for us with top, skip, filters.
In the service implementation, right click on the entity and map to data source, here map the same to CDS view. Hello, Mahesh kumar palavalli. You can even map a database table or view. I try to call method to include more data in entity while GET request is initiated for the entity. If the service is not generated from the CDS view then yes it is possible as you will be doing it via the reference odata source or entity set binding to individual cds view.
Yes I do. You confirmed something I only could guess about. Thank you very much for your valuable response! Is it possible to access data from a database table of another system in this method? What I need to achieve is to fetch data from another odata service and its entity. My solution is to the stuff on frontend, accessing two different OData services.

Any of you have an idea of how can I get these other operations? Or is there a documentation where I can follow how to build that? Please take a look herehere and here. I am not very expertized here, but in the 2nd link that you attached me, there is a step-by-step guide to create a UI5 App I close this question.
