Defining and using naming conventions ensure consistency in the names used by all the developers on a project. This posts summarizes the naming conventions recommended by SAP for the RAP Development Objects.

General Rules

The overall object name will be split into 3 parts.




For custom object, the namespace can just be Z. Your project can also have a namespace like ZAB_ etc.


Prefix is used to differentiate between different types of same development object. For example, Root Entity and Projection Entity can be differentiated using the prefix.

Meaningful Abbreviation

This can be any meaningful text separated by _ characters. For example, customer_name.


Suffix can be used for additional differentiation between different types of development objects. For example, a service binding with UI service can be named with suffix _V2 for OData version 2 and _V4 for OData version 4.

With this explanation, let us understand how the RAP development objects can be named. For the examples the namespace used is ZJP_.
