Internal error when redefinind service with entity types and associations

Dear gateway specialists,

I have created a gateway service with several entity types and several associations together with corresponding navigation properties.

Then I have created another service in which I want to redefine the first service with all the entity types and associations.

But the redefinition ends with an internal error (message no. /IWBEP/SBCM001) and the navigation properties are not imported (entities and associations seem to be o.k.).

What could be the reason for the error? And why might the navigations not be imported?

Thanks!

Regards,

Juergen

P.S. I found SAP note 2027049 "Service Builder Redefiniton - Extend of Odata service with Associations" which I've implemented, but without success
