[raghava99]

Hi Everyone,

Please suggest me how to enable create button.

You have to start the preview for the root entity. You then select the singleton entity to be able to edit the other entities of the RAP BO.

@raghava99: the generated business object checks the authorization object S_TABU_NAM with the CDS entity <your_entity> and the activity 03 (read) / 02 (modify). Check the generated Access Controls and the generated behavior implementation class for the authorization check. If you are not able to extend your user with the required authorizations, you could delete the Access Controls objects and disable the authorization check in the behavior implementation.
