Association Navigation not working - IW_BEP SP09

Hi ,

we have created association , association set and Navigation properly but still its not working.

Recently we moved our code from a system which has IW_BEP SP08 to SP09 , in SP08 it was working perfectly but not now.

Also i found that if i delete the associations and try to generate the project , still i can see the Associations in MPC class ( DEFINE_ASSOCIATIONS)

and if i create new ones , they are not getting reflected in the class as well.

Another problem is , sometimes the classes are shown locked by user and we have to go to SM12 and release the locks for the classes. this issue we are facing in IW_BEP SP09

Is there any sap notes released by SAP to solve this problems ?

Thanks
