To use the S/4 HANA CDS (Core Data Services) model using VDM (Virtual Data Model), you need to follow these steps:
Install the required tools and software: Make sure you have the necessary software installed, such as SAP Development Tools (ABAP Development Tools for Eclipse) and the SAP Cloud Platform ABAP Environment.
Set up your development environment: Configure your development environment by connecting to the SAP Cloud Platform ABAP Environment and creating a new project.
Define your CDS views: Create the CDS views that you want to consume using VDM. CDS views define the structure and behavior of your data models in the ABAP language. You can use annotations to enhance the metadata of your views and enable specific functionalities.
Generate the VDM classes: Use the ABAP Development Tools for Eclipse or the SAP Cloud Platform ABAP Environment to generate the VDM classes based on your CDS views. VDM classes provide an object-oriented representation of your data models and allow you to access and manipulate the data.
Write your application code: Start writing your application code by using the VDM classes. You can perform various operations such as querying data, creating or updating records, and executing actions defined in your CDS views.
Deploy and test: Deploy your application to the SAP Cloud Platform ABAP Environment and test it to ensure that it works as expected. You can use the provided testing tools or develop your own testing scenarios.
the specific steps and tools may vary depending on your SAP system version and setup. It's recommended to refer to the official SAP documentation, guides, and tutorials for detailed instructions on using S/4 HANA CDS models with VDM.
