This documents addresses interfacing through OData specifically. Download from the link and when creating a new form select "Import from a Form Definition File. In order to securely login to SAP, create a new system account with the login details for the target SAP system username and password.
As there are some really good tutorials on this subject in SCN and other blogs, initially we deferred the idea to write on the same topic. But now, with the repetitive request from our beloved subscribers, we would try our best to put the series on OData and NetWeaver Gateway in a simple and systematic way so that all the beginners on this topic can learn and benefit from our page.
The protocol is a set of rules which every player has to follow. To put it straight, OData interface is an open standard that can be consumed by any application, program, software or device of the Non-SAP World that can connect with SAP using the HTTP s protocol and can manipulate read, write, modify and understand i. In other words, OData is a Web protocol for unlocking and sharing data; freeing it from silos that exist in some software applications.
With OData, developers are able to build cross-platform Web and mobile Applications. With OData, organizations can develop services with the high levels of data integration and cross-platform interoperability that are required by the modern day complex business.
Also note, OData is an open source to exchange data over the Internet. But the scenario has changed with OData. Both of these formats are well known, plain text protocols for the transmission of information over the Web.
OData message is self-describing. It is understood by now that Server hosts the Data and Clients can call the Service to retrieve the resources and manipulate them.
Servers expose one or more endpoints which are Services that refers to the Resources. Clients or non-SAP World developers only need to know the Server side endpoints to call the service to query or manipulate the data. It is an Open book now. There is no cost or license agreement needed for the use of OData.
Not SAP. Surprise for an ABAPer. Citrix Systems Inc. Ans: OData offers database-like access to server-side resources. Similarly, OData acts like middleware between producers and consumers to communicate data. One application for two different organizations or platforms needed two different design in SAP. This led to duplication of work, effort, time and money. Check the below image. This mean there was poor scalability, increased system landscape complexity and increased administration effort.
Please check the image below. This approach provides one solution to any environment, any platform and any experience. This is particularly useful in cases where SAP specific values need to be described in this protocol; for instance, currency fields.
A currency field contains two separate values, the currency amount and the currency code. So it deserves a small mention. Web Servers do not remember or recall the previous request. This is called stateless. REST is an architectural style that uses simple and lightweight mechanism for inter-machine communication. So, the client does not need to know what the exact operation name defined in the service contract to call that method.
GET method is used whenever we need to get the representation of an existing resource. POST is used to add new resource into the system. Still confusing? Let us try to understand with the below real example Do not worry, how we created it.
We will learn how to create them in our next post. These verbs are uniform and standardized for all OData. It is also important to note here that it is possible to have multiple URIs pointing to the same Resource with the same output. Let us check it with the below example. Ans: At NW 7. After 7. In the subsequent parts, we will dive deeper in the actual practical scenarios of OData.
We will also check Navigations and Associations of Data Models and learn how to handle them. Nice post! I am really interested by the possibilities of Hi, nice blog Do you have any example of employee central Toggle navigation. Cash and Liquidity Management Configuration Mar 11, Mar 9,
There is so much information and seemingly new technologies available about developing mobile and responsive applications within SAP at the moment it makes it very difficult to know where to start. How do these all fit into the big picture for an SAP developer? Well let's start at the ground level i. Step 1 - SAP Netweaver Gateway Service Builder First go to transaction SEGW where you will be able to build your service Step 2 - Create project Next using the create button you have to create a project to store all your data models, implementtions, entity types, entity sets etc. Don't worry too much about the terminology at this stage, all will become clear.
Thank you for interesting in our services. We are a non-profit group that run this website to share documents. We need your help to maintenance this website.
This article should give a fair idea about the tit-bits of handling PDF printing in the gateway. Create a gateway project Follow the previous blogs for details of creating a project and subsequent actions. Create a separate entity to handle the media operations. Generate the runtime artifacts of the project. Basic method coding is explained below.
OData Service The service metadata document is a lot more detailed th an the service document and shows all metadata of the service. A short summary of this paper. Context A context represents a source of ODPs.
