2715644 - Language Key Inconsistent in OData of Custom CDS View

The value of any Language field of a custom CDS view is only a single character, but in the OData service for that view, the Language field is 2 characters

SAP S/4HANA Cloud Public Edition

1. Create a custom CDS view using the Custom CDS Views app
2. As the primary data source pick a source that has a field called Language
3. Ensure that OData API is selected for this CDS view so that an OData service is created for the view
4. Publish the view, and preview the data
5. At this point you will see that the value of the Language field is always a single character
6. Set up a communication scenario and arrangement so the OData service can be accessed via a browser
7. Now access the OData service to see the data that is in the view
8. Notice that the values for the Language field are now displayed as 2 characters

• For views with the Language field there will be a built in association to the _Language view
• This _Language view contains the Name for the Language, as well as the ISO Code for the language
• It is the ISO Code that is displayed in the OData service

• This is working as expected, the ISO Code is more valuable to most users, so it is the one displayed in the OData service
• The single character language code is called te SAP Language Code
• The relation between the ISO Code and the SAP Language Code are described at Supported Languages and Code Pages
