DCO Rejection Error

I am trying to implement Express DCO into our V11 PLM.

We use simple ECOs for changes to the cad documents.

 

All of the functions seem to work except for the rejection.

Anyone at an administrator level can reject a document at voting but normal users get an error.

               Internal Error: failed to get the transition to promote the Document from In Review to Preliminary.

                               <faultstring>Internal Error: failed to get the transition to promote the Document from In Review to Preliminary.</faultstring>
