I am unable to find the cause, But to resolve that i delete the Baseline from Draft and Publish Database , and its start working fine.

How to Delete Baseline Record from Database:



Delete
from MSP_TASK_BASELINES
where MSP_TASK_BASELINES.PROJ_UID ='GUID of Project' AND MSP_TASK_BASELINES.TASK_UID NOT IN
 (
select TASK_UID
from dbo.MSP_TASKS 
where PROJ_UID ='GUID of Project'
)

Replace  Project GUID According to your Project ID

Run this query for Draft and Publish DB , After Execution you will see n number of Rows deleted for DB.
go to Project Plan and Publish it again, You will see now its also populating data in Reporting DB AS Well.
