The class actor generated by the persistent objects wizard (CA_persistent) inherits from the abstract CB_persistent class.

This means you cannot inherit from another class into the persistent class because ABAP does not support multiple inheritance.

thank you for reply.

but i have used inheritance when defining the persistent class.

now when i try to call method create persistent of CA class it only creates the instance of subclass not the base class

any idea?
