how to birng the data in data sources for the first time

Dear Gurus,

For the Personnel Development (0PAPD) i installed the datasoures 0HR_PA_PD_1, 0HR_PA_PD_2 from ECC and checked in RSA3 I found 0 records.

My question is any configuration should be done to bring the data into datasources. But in ECC there module is implemented and gone live long back ago, they are telling data is there in tables also.

Regards,

Kiran
