SubscribeController.m:63 SUPPersistenceException: SUPPersistenceException from synchronize:Message: Failure occurred while executing user supplie

Hi All,

I have downloaded sample app from http://scn.sap.com/docs/DOC-8803  (SUP 101 - iOS Project (2.1.3)) for SUP2.1.3 and I replaced generated code.But after running sample app I am getting following exception: [SubscribeController.m:63] SUPPersistenceException: SUPPersistenceException from synchronize: -- SUPSynchronizeException: Sync failed: -857 (ERROR) %1:[-10225] Message: Failure occurred while executing user supplie.

I do not know why I am getting this exception?Please help me to resolve this.

Thanks in advance!
