How to configure this OWL?

Hi guys:

I create a BO like this:

businessobject Test{

element ID :IdentityID;

element name :LANGUAGEINDEPENDENT_MEDIUM_Name;

}

then I create screens.

However when i log on the tenant and click my work center,i can see all data created by other users! if i just want to see the data i created,what should i do?
