Problem creating the proxy - PRD

Gentlemen,

I'm having an unusual problem.

I'm developing a SOAP synchronous interface. She is working perfectly in DEV/QAS.

I carry the objects of the IP and when I climb the requests of the ECC, the proxy gets a red circle, leaving use the same in PRD environment.

I noticed a difference between the environments, the Enterprise Services Builder PRD, the following message appears: Invalid Objects with References.

I've tried retransportar the requests that create the proxy, I tried working in a new namespace, clear cache ... however the problem persists.

Have you seen this problem?

Thx!
