How to call the second entity set from first entity set

Hi ,

i have a header and item entities in my application .

i have dispalyed all header data in one view and i want to display  item data in another view.

Now ...i created a navigation between first entity and second entity . but i am not sure how to call/test the Odata to get the detailed item data from Header data.

pernrSet is my first entity and DetailSet is my second entity and my Navigation Name is - Association.

i am testing the Odata for Second Entity through the below link. Please tell me if i am wrong somewhere.

/sap/opu/odata/sap/ZEMPLOYEE_SEARCH_SRV/pernrSet('00000010')/Association
