Hi Manjusha,
please check out the Project Management Domain, it contains both project and some resource information for the ressources allocated to the projects.
Vice versa, the Resource Management Domain shows the resources and the investments they are allocated to.
Missing in both domains are the time sheets, which you will find in the Time Management Domain.
In case you would like to combine the time sheets with the Projet/Resource Management Domain data, you will have to extend the OOTB domains by joining in the missing tables from the Time Management Domain. For this, some SQL knowledge is required.
Regards
Georg
