ODS generated objects

Hi experts,

I have a custom created ODS, for which I have not set the option " Update data targets automatically". But when I see the generated Objects under the data mart, I am seeing new info source has been created and a new PSA table gets created for every load of the ODS. Why this happens. How to prevernt this happening. Infact, I donot have any design requirement to further update to any other data targets

thanks

D Bret
